Notes: Bioherms found in the Lower Permian Tyrrellfjellet Member of Central Spitsbergen contain bindstones produced by the ?hydrozoan taxon Palaeoaplysina. We briefly describe the bioherms’stratigraphical and environmental setting and note their development on hardground surfaces. The association of these structures with bituminous limestones is interesting in view of the petroleum resources of similar buildups in the USSR.

Notes: Aeolian deposits are described in terms of their areal distribution, sedimentary and pedological characteristics. These deposits, which have accumulated at the valley margins, result from deflation of fluvian sediments deposited in the valley bottom. Fine horizontal lamination in the upper horizons is tentatively attributed to winnowing of primary depositional units following partial cementation by salt precipitates. This stratification breaks down at depth and is replaced by a gleyed horizon, resulting from drainage impedance by permafrost. Proximal aeolian accumulations on flu-vially inactive areas of the valley bottom may typify many other valleys in Spitsbergen.

Notes: Occurrence of Salterella rugosa Billings on Nordaustlandet, Svalbard, is reported for the first time. The rocks that produced these fossils belong to the upper part of the Kapp Sparre Formation. This unit can be correlated with the Oslobreen Dolomite in Ny Friesland (Spitsbergen, Svalbard) from which the same species has been reported earlier; these fossils have not been illustrated previously. In both areas many specimens are poorly preserved, and it is becoming increasingly evident that the difference between Salterella and Volborthella simply may be the result of loss of the outer shell in the Volborthella.

Notes: Foraminiferal faunas were analysed from 22 cores (length 30-165 cm), three grab samples and one dredge sample taken from Spitsbergenbanken and the trenches Storfjordrenna and Bjørnøyrenna. The distribution pattern of selected taxa and eight assemblages are discussed in relation to water depth, currents and sedimentation. The assemblages found on Spitsbergenbanken where currents are particularly active, are clearly different from the assemblages occurring in the more quiet environments of the trenches.In the Quaternary evolution of the area three successive stages are distinguished: glacial shelf environment of the Weichselian; semiglacial, or transitional environment of the Late Weichselian and Early Holocene; open, or deglaciated shelf environment of the Holocene. Minor faunal changes in Storfjordrenna are explained by changes in the current pattern.In some assemblages marked postmortem changes have taken place which include solution of calcareous shells, breakage and abrasion by currents, and transport of shells out of the high energy bank area with assumed redeposition in deeper water.

Notes: The pre-Carboniferous miogeosynclinal sedimentary and volcanic sequences of south-central Prins Karls Forland belong to a suite of rocks known as the Forland Complex. During early Palaeozoic diastrophism the Complex of Prins Karls Forland experienced predeformational, low grade metamorphism. A knowledge of the stratigraphy and structure of the region, together with an analysis of metamorphic mineral assemblages and reactions enable the conditions of metamorphism to be determined within certain limits. It is found that temperatures during metamorphism were between 400°C and 500°C, and pressures were about 6 kb. These conditions provide an estimate of palaeogeothermal gradient, consistent with observed mineralogies, of 18 to 21°C.km−1. In addition, compositional variations within mineral phases are found to be largely dependent upon bulk-rock chemistry, and are of limited use in determining grade changes.

Notes: The Orustdalen Formation of Brøggerhalvaya is well exposed on two coastal sections and is 200–250 m thick. It consists dominantly of siliceous conglomerates and sandstones with subordinate shales and impure coal. One horizon low in the sequence yielded spores of uppermost Dinantian/lowermost Namurian age. Three sedimentary fades have been recognised. The fluvial channel facies (interbedded conglomerates and cross-stratified sandstones) are interpreted as braided stream deposits with flow directions to south and west. A shale facies, sometimes with drifted plant remains, is interpreted as overbank in origin. Highly quartzose, medium-to-coarse-grained, cross-stratified sandstones make up the reworked facies where palaeocurrents are bimodal or indicate movement to the NE. The Formation is thought to represent sediments shed from an early Carboniferous fault scarp eroding’a siliceous Lower Palaeozoic source terrain. The proximity of a nearby coastline led to the construction of fan deltas where fluvial deposits were reworked by waves and/or tides. Early diagenetic events include the local development of pyrite, kaolinite and calcite cements. Reddening’probably occurred during Middle Carboniferous times beneath an exposed land surface. Following burial, pressure solution and quartz cementation eliminated porosity at depths greater than 1000 m.

Notes: : Samples were collected upstream and downstream of Schwatka Lake, Yukon Territory, to examine nutrient transport through a small northern impoundment. Annual loads were estimated for total phosphorus, nitrate plus nitrite, total dissolved nitrogen, silicate, total inorganic carbon, and total organic carbon. Transport of these materials out of the impoundment was greater than estimated for the upstream location. Results of a short term temporal study confirmed that the output exceeded the input to the lake. There are several processes which might be responsible for this occurrence, of these, ground water contributions appear to be the active process.

Notes: : An evaluation of flood frequency estimates simulated from a rainfall/runoff model is based on (1) computation of the equivalent years of record for regional estimating equations based on 50 small stream sites in Oklahoma and (2) computation of the bias for synthetic flood estimates as compared to observed estimates at 97 small stream sites with at least 20 years of record in eight eastern states. Because of the high intercorrelation of synthetic flood estimates between watersheds, little or no regional (spatial) information may be added to the network as a result of the modeling activity. The equivalent years of record for the regional estimating equations based totally on synthetic flood discharges is shown to be considerably less than the length of rainfall record used to simulate the runoff. Furthermore, the flood estimates from the rainfall/runoff model consistently underestimate the flood discharges based on observed record, particularly for the larger floods. Depending on the way bias is computed, the synthetic estimate of the 100-year flood discharge varies from 11 to 29 percent less than the value based on observed record. In addition, the correlation between observed and synthetic flood frequency estimates at the same site is also investigated. The degree of correlation between these estimates appears to vary with recurrence interval. Unless the correlation between these two estimates is known, it is not possible to compute a weighted estimate with minimum variance.

Notes: : Winter heat budget and frazil ice production in the St. Lawrence River between the Ogdensburg-Prescott Boom and the Moses-Saunders Power Dam are analyzed. Contributions of each heat exchange component, and spatial distributions of heat exchange rates are calculated for three typical winters. Based on the calculated heat budget, the amount and distribution of frazil ice generated in the study reach is analyzed. The result of this study indicates that the thermal energy contained in the river water flowing into the study reach is a dominate factor in the heat budget analysis. The heat flux from the channel bottom accounts for an important portion of the total heat budget during the ice covered period.

Notes: : This paper discusses the economics, advantages, potential applications, and status and future research needs of porous pavements. Porous pavements are an available storm water management technique which can be used on parking lots and low volume roadways in order to reduce both storm water runoff volume and pollution. In addition, ground water recharge is enhanced. Also, cost reductions result due to elimination of curbs, drains, and small sized storm sewers. Porous asphalt pavements consist of a relatively thin course of open graded asphalt mix over a deep base of large size crushed stones. Water can be stored in the crushed stone base until it can percolate into the subbase or drain laterally. Other porous pavement types include concrete lattice blocks and a porous concrete mix.

Notes: : Municipal water supply restrictions and/or conservation policies are widely believed to affect urban growth, at least in Western states. An analysis of this issue, drawing upon a wide array of empirical water use research, casts doubt upon the presumed connection. Water availability seems likely to have little effect upon the amenities which draw newcomers to Western cities. It also seems to have little effect upon the locational decisions of industries which affect growth by creating new jobs. Consequently, there is little reason to oppose municipal water restrictions as prejudicial to urban growth or to favor such restrictions in the hope of constraining growth.

Notes: : Sequential water reuse by various users, i.e., municipal, industrial, agricultural, is common practice in all river systems. In the arid and semiarid western United States where streams are not large and water demands are high relative to the virgin water supply, the practice causes a reduction in stream flow and an increase in stream salinity. This paper outlines a quick and easy application of the materials balance principle to approximate the effects of increasing the level of sequential reuse on residual stream flow and salinity.

Notes: : The cost of sanitary facilities is a major cost item in recreation areas at water resources projects. Often planners wish to analyze the tradeoffs in providing different levels of service at these areas. Cost functions are presented in this paper to enable the planner to make quick comparisons between different types of buildings, sizes, exterior treatments, and number of fixtures.

Notes: : Three hydrologically different water bodies located at the urban fringe of Metropolitan Syracuse, New York, were monitored using field equipment to determine the effect of dilution on water quality in response to precipitation events during Summer 1980. Conductivity was the primary parameter since the portable meter used to obtain readings provided an immediate indication of dilution of the dissolved solids content of base flow. Results show that water quality is a complex function of hydrologic, precipitation, and watershed characteristics. In the ground water pond, dilutions ranged from 50 to 150 micromhos/cm as a result of direct precipitation and overland flow. These dilutions along with increasing conductance as evaporation losses increased were indicative of the role of the pond as a “sink,” as opposed to being a part of a flow through steady state system. Watershed orientation governed dilution of base flow in Butternut Creek. The westerly summer storm track moves across the narrow Butternut Creek. The watershed, the orientation of which is northerly, so that the drainage area exposed to precipitation was minimal. Dilution ranged from 50 to 200 micromhos/cm. In the Butternut Feeder Canal (created by withdrawal from Butternut Creek), extreme fluctuations reflected the localized land use, in particular the imperviousnes of adjacent urbanized hillsides. This investigation suggests guidelines to further assess the impact of Meadow Brook and storm sewer input on the Feeder Canal. The water level in a section of Old Erie Canal State Park is maintained by the Feeder Canal. Therefore, it is imperative that jurisdictional agencies complete this assessment. On a broader scale, this study demonstrated the value of field equipment as a viable alternative to expensive instrumentation if the data to be generated are of general, descriptive use.

Notes: : Transmissivity and storativity of an aquifer are usually determined by analysis of steady or nonsteady pumping test data. The classical methods of nonsteady pumping test analysis are mostly graphical in nature and are, therefore, subject to errors of judgment in curve fitting, interpolating, and reading graphs and charts. A method is described here which does not require construction of graphs or use of charts and tables. The transmissivity and the storativity are calculated using regression analysis of the nonsteady time drawdown field data. The calculations can readily be performed on a hand held calculator. The procedure is described using four examples, and the results are compared with those obtained from graphical techniques. It is shown that the method is a viable alternative to the type curve solution of Theis or Straight line solution of Jacob for nonleaky artesian aquifers. However, the regression method poses problem in the cases of leaky artesian and water table aquifers.

Notes: : Phytoplankton were studied in lakes augmented with water from the Floridan aquifer and in control lakes. Augmented lakes exhibited enhanced phytoplankton diversity which was believed to be related to chemical changes in the lakes brought about as a result of ground water addition. In particular, elevated concentrations of inorganic carbon appeared to influence phytoplankton populations.

Notes: : Site specific studies of water based recreation participation are intended to describe use at a particular recreation area. Two common strategies employed in site specific studies are the on-site “entry” or “exit” survey and the off-site mailed questionnaire to known users of an area. Previous research has reported differences in psychological perceptions of a recreation engagement depending on whether a survey was administered during or after a trip. If such bias exists for behavioral reports, then managers and planners must be cautious in interpreting results of survey based use assessments for a particular site. Findings may be affected by the particular survey strategy employed. In this study, entry point and post-trip mailed questionnaire measures of water based recreation participation were compared for a sample of reservoir users. For most activities, a high degree of consistency in measures was found. Inconsistent reports were most likely to occur among participants in activities sharing significant common behaviors, such as power boating and water skiing. Inconsistency was also observed for those reporting very generalized behaviors, such as relaxing. In general, the use of either pre- or post-trip measures of water based recreation participation was supported.

Notes: : In addition to offsetting water supply shortages, water conservation is recognized as serving many purposes, ranging from reduced energy consumption to lower capital costs. Since the discussion of these benefits has been a recent development and has generally excluded local water supply managers, a question arises as to whether supply managers are implementing conservation programs to exploit these benefits. A survey of the managers at 35 Maryland water utilities provides insight into the prevailing attitude toward conservation in a water rich eastern state. The results indicate that most managers continue to view conservation only as a short term response to temporary supply shortages. Only 12 Maryland utilities have undertaken any form of water conservation activity and just two systems have ongoing, comprehensive conservation programs. Institutional, perceptual, economic, political, and time constraints all contribute to the managers’attitudes and general inaction. If water conservation is to be widely practiced, these issues must be addressed and the benefits attributed to conservation must be better documented and articulated to supply managers.

Notes: : Hydrograph analysis of six streams on the south shore of Long Island indicates that eastward urbanization during the last three decades has significantly reduced base flow to streams. Before urbanization, roughly 95 percent of total annual stream flow on Long Island was base flow. In urbanized southwestern Nassau County, storm water sewerage, increased impervious surface area, and sanitary sewerage have reduced base flow to 20 percent of total stream flow. In an adjacent urbanized but unsewered area in southeastern Nassau County, base flow has decreased to 84 percent of total annual stream flow. In contrast, base flow in two streams in rural areas has remained virtually constant, averaging roughly 95 percent of total annual flow throughout the 1955-70 study period. Double-mass curve analysis of base flow as a percentage of total annual stream flow indicates that (1) changes in stream flow characteristics began in the early 1960's in the sewered area and in the late 1960's in the later urbanized, unsewered area, and (2) a new equilibrium has been established between the streams in the sewered area and the new hydrologic characteristics of their urbanized drainage basins.

Notes: : The relationship between chlorophyll u, total phosphorus, secchi disk depth, and trophic state were examined using data on U.S. lakes collected by U.S. EPA's National Eutrophication Survey. By comparing predicted secchi disk depths with observed summer secchi disk depths in 757 lakes, it was determined that in many lakes non-chlorophyll related light attenuation is important in controlling the amount of chlorophyll u produced per unit of total phosphorus. Ranking of 44 lakes by 18 different trophic state measurements and single and multivariable indices were compared with rankings provided by mean summer ambient total phosphorus and chlorophyll u. The trophic state measurements and indices were much more successful in ranking the lakes against total phosphorus than chlorophyll u, indicating that there are differences in the relative trophic rankings of many of the lakes depending upon whether primary nutrients or biological manifestations are used as the ranking mechanism. If the manifestations of nutrients rather than their absolute levels are the primary criteria for beneficial use of lakes, the use of many of the commonly employed trophic state measurements, which assume or imply that there is a constant relationship between total phosphorus or secchi disk and chlorophyll, can lead to erroneous conclusions and unnecessary costly management controls. Secchi disk measurements may be more useful as a predictor of ambient lake total phosphorus concentrations than of chlorophyll.

Notes: : The detection of change in a hydrologic varaible, particularly water quality, is a current problem. A method is presented for testing whether there has been a shift in the mean of a hydrologic variable based on the well established bivariate normal distribution theory. In this technique, the dependent, or target, and the independent, or control, variables are formed as weighted linear combinations of the mean values at a number of locations in a selected target and control area. The weighting factors are determined based on a mathematical programming technique which minimizes the conditional coefficient of variation thereby minimizing the number of observations required to detect a change of a preselected magnitude in the mean of the target area. The result is a situation where a savings in the number of observations required to detect a change is a consequence of adding more stations: the space-time tradeoff. Two applications of the technique are presented, the first using electrical conductivity (EC) data from two sets of river basins and the second using EC data from a set of basins as the target variable and annual discharge as the control. The results indicate that a significant savings in time can be achieved by using this method.

Notes: : A computer model was developed in order to establish a yield predictive relationship and to estimate the water requirements for supplemental irrigation of horticultural crops in the humid region. Alternative distribution systems were developed and designed using the results from the computer model and Wood's (1980) pipe network algorithm. The capital, operational, and maintenance costs of the distribution and recommended on-farm irrigation systems were determined and used to evaluate the economic feasibility of the alternative designs. Results show that the concentration of irrigated area along the distribution system, the length of the distribution system, and cropping system all have an important effect on the economic feasibility of supplemental irrigation in Wayne County, Kentucky.

Notes: : Specific annual suspended sediment yields and their standard deviations are presented for 47 basins of North Island, New Zealand. Most of the variance in yields is explained by catchment mean rainfall. Rivers with similar flow range have similar suspended sediment concentration ratings, independent of differing watershed lithology and regolith, except for six basins having an abundance of soft fine sediments. Prediction equations for yield and its standard deviation are derived for four essentially arbitrary regions. AU feature rainfall as the independent variable. Differences between regions may owe to variations in intensity, frequency, and duration patterns of storms and, in one area, to bed material size as well. The temporal distribution of annual yields from a basin m be modeled by a two-parameter lognormal function: the prediction equations above may be used to evaluate this function at a site for which suspended sediment data are unavailable.

Notes: : Trophic classification of the Canadian nearshore waters of the Great Lakes is attempted using summer, surface water quality data for the early 1970's. A generalized Composite Trophic Index is developed using paired linear relationships for total phosphorus, chlorophyll a, and Secchi depth data for 66 defined nearshore regions. The chlorophyll a and total phosphorus relationship indicates that the nearshore waters contain a low chlorophyll a concentration for a given total phosphorus concentration than observed for the open waters of the Great Lakes or for smaller Canadian lakes. The most eutrophic nearshore regions occur in areas of relatively restricted circulation and/or high nutrient loadings. These include the Bay of Quinte, Toronto and Hamilton harbours, and portions of Lake We's Western Basin. Lakes Huron and Superior are generally oligotrophic, except for some embayments. Although nearshore water quality is highly variable, this apprach represents a reasonable compromise with respect to analytical complexity. The Composite Trophic Index removes biases introduced through the use of a single trophic state indicator and uniquely describes the nearshore water quality in terms generally comparable to other water bodies.

Notes: Design freeboard is an increment of height added to a dam, floodwall, levee, or channel, above and beyond the design flood height, intended to serve as a safety factor to account for unforeseen errors in design. Current policies of the Corps of Engineers with regard to the handling of design freeboard for local flood protection studies in economic analyses lead to economic inefficiency. An analysis of these policies in the case study of a levee raising plan for Wyoming Valley, Pennsylvania, reveals that a $200 million project which is considered economically justified under anent policies is in fact not justified under strict economic efficiency criteria Congress has directed that water resources development projects be planned for the objective of National Economic Development. Under current policies that is not being done.

Notes: : A decision model for optimum cropping pattern and ground water manaement alternatives in canal irrigated areas is pre sented. Various ground water management alternatives in conjunction with optimum cropping pattern and based on water production functions are compared. The model developed also ensures optimum utilization of surface and poor quality ground water and proper soil conditions for plant growth.

Notes: : The history of the Milwaukee water pollution abatement program is examined as a case study to investigate the costs of conflicting environmental policy. The recent U.S. Supreme Court decision concerning the Milwaukee case is described as a milestone in U.S. water pollution abatement policy which will help preclude the type of environmental policy conflict which has been found to be so costly to Milwaukee. The implications to U.S. water pollution abatement policy of the 13-year history of conflict in Milwaukee are presented.

Notes: : In developing water quality models for lakes and reservoirs, the assumptions of one-dimensionality (i.e., water quality changes are significant only in one dimension – usually depth), as well as two-dimensionality (considering the length and depth of the water body), have been utilized to predict water quality. In both caws, the assumption of lateral homogeneity is made. A field study was undertaken to determine the change of water quality in the lateral dimension. The main study reservoir was Center Hill Lake in Middle Tennessee. Data were also obtained for Cherokee Lake in East Tennessee. Several water quality parameters (temperature, dissolved oxygen, pH, conductivity, and oxidation reduction potential) were analyzed over the length, breadth, and depth of these reservoirs from pre-stratification through post-stratification. The statistical and theoretical three-dimensional analysis showed the expected variation for each water quality parameter in each direction. The influence of the lateral dimension on water quality management and modeling was found to be negligible.

Notes: : Artificial recharge as a means of augmenting water sup plies for irrigation is a management alternative which policy makers in ground water decline areas are beginning to consider seriously. A conceptual model is developed to evaluate the economic benefits from ground water recharge under conditions where the major water use is irrigation. The methodology presented separates recharge benefits into two components: pumping cost savings and aquifer extension benefits. This model is then applied to a Nebraska case to approximate the value of recharge benefits as a function of aquifer response. discount rate, and commodity prices. It was found that recharge benefits vary from less than $2 to over $6 an acre foot recharged.

Notes: : A method of predicting annual flows is presented and is applied to the Fraser River catchment. Statistical tests show the annual flow records to be stationary and aerially independent and can be adequately approximated by Gaussian distributions. Estimates are made of the Gaussian parameters for each subbasin. The spatial variations of these parameters are described by third order trend surfaces. The fitted surfaces can then be used to predict parameters of ungaged basins using the latitude and longitude of the basin centroids. The predicted parametric values are substituted into the Gaussian distribution to generate flows of various return periods.

Notes: : Recovery of eutrophic lakes after nutrient diversion may be delayed if the lake experiences significant internal phosphorus (p) loading to the water column. A maximum dose of aluminum sulfate, defined herein, was applied to the anaerobic sediments of the hypolimnia of two dimictic Ohio lakes following septic tank diversion, with the objective of attaining long term control of the release of phosphorus to the water column from these sediments. The results were compared to a similar, downstream, untreated lake. Total phosphorus concentration declined sharply after treatment and has remained so through 1980 for both lakes, a period of 5 and 6 years of control, respectively. Internal P loading from anaerobic, hypolimnetic sediments was partially controlled by the treatment but there are other important sources, perhaps in the littoral zone, in these lakes. Algal biomass is Smaller and water transparency has increased. Both lakes became mesotrophic after treatment, as described by the Carlson (1977) trophic state index, and remain in that improved condition to date. No deleterious side effects were observed, although one lake experienced a significant decrease in diversity of planktonic microcrustacea and a lakeward extension of the macrophyte community. This method appears to be an effective and lasting means of accelerating the recovery of a eutrophic lake following nutrient diversion.

Notes: : Artificial substrates were designed using rock filled polyethylene bags which were perforated with holes. The substrates trapped waterborne sediment and detritus which enhanced microhabitat complexity. Colonization was compared in side-by-side tests with multiple plate samplers in mountain streams ranging from second to seventh order. After 41 days the bag samples contained more sediment and detritus and more animals than did multiple plates. Plastic bags exceeded multiple plate samples by a factor of nearly 8 for individuals and 1.5 for taxa expressed as numbers/sampler. Although detritus amounts differed significantly between samplers, catch composition was similar in habitat preference and functional groups. Most taxa were “lotic erosional” or “lotic erosional-depositional” detritivores. The plastic bags better represented the streambed fauna judged by their greater similarity to dip net samples. Bag samplers had 4.5 × the colonization area of multiple plates, hence would be expected to support more species. Catch/m2 of colonization area was not significantly different between samplers. Functionally the plastic bags act as detritus retention devices, offering a diverse, highly dynamic microhabitat for colonization. Results are interpretable in terms of research on microdistribution of stream benthos and the river continuum model. This study supports the conclusion that stream benthos abundance and diversity are related to the amount of detritus. Maximum diversity and numbers of individuals occurred in samples from third and fourth order streams. Grazers reached peak abundances in the same streams where the continuum model predicts P〉R Shredders reached maximum abundances in third and fourth order streams where the riparian canopy was greatest. Predator abundance changed little with stream size. Although bag samples required more sorting time, the samplers are catch effective, inexpensive, and adaptable.

Notes: : There are unpublished reports of rapid and large rises in the water table which are out of proportion to the infiltrated volumes of water. The phenomenon seems to result from the conversion of a tension saturated zone to phreatic water by one of several mechanisms. The effect could be triggered when the tension saturated zone intersects: the ground surface, a saturated soil horizon, or a coarse zone. The phenomenon could prove to be a common link in explaining several seemingly diverse phenomena which characterize non-Hortonian runoff in a humid environment. Under certain conditions storm peaks are dominated by flow from small, restricted, “variable source” areas that contributed runoff when saturated from below by rising water tables; for other streams, ground water input forms the major part of the flood peak. The explanation for these observations could lie in an understanding of the rapid water table rise phenomenon. Such a mechanism. if widespread, would provide the means for producing saturation at or near the surface shortly after rainfall commences. The phenomenon should be documented and closely analyzed from a number of perspectives to define its true role in the hydrology of humid environments.
