    Notes: Abstract. Currently there is growing interest in the restoration of drained peatlands in Britain. In order to investigate some of the effects of changes in land management practices on the biogeochemistry of peatlands, a field experiment was designed to manipulate the hydrological conditions in a naturally drained acid gully mire in Mid-Wales. We report preliminary results of the effects of experimentally rewetting the mire on the hydrochemistry of bromide in the peat-water. Results show that rewetting had a dramatic effect on the concentrations of bromide, which increased substantially. Peak values approached 1 mg/dm3 in some samples following rewetting, compared with typical values 〈 0.05 mg/dm3 under the drained conditions. Bromide was positively and significantly correlated with Dissolved Organic Carbon (DOC) in the peat-water, which suggests that Br- is derived from breakdown of organic matter in the reducing conditions following rewetting. The bromide mobilized by rewetting may be leached out of the system and/or re-assimilated by the wetland vegetation. Further monitoring is needed to determine whether the observed hydrochemical response of bromide to rewetting of the mire has any longer-term effects.

    Notes: Abstract. Recently, there has been interest in the occurrence of bromide (Br-) in natural waters since it has been demonstrated that Br-, in association with humic substances in raw waters, is readily incorporated into haloacetic acids in the form of organically bound bromine (Br) during water chlorination. We report results of the effects of experimentally rewetting a naturally drained gully mire on the hydrochemistry of Br-, iron (Fe) and dissolved organic carbon (DOC) in the peat water. Results obtained over a three year period showed that rewetting substantially increased the concentrations of these solutes in the pore water, with peak values of 1 mg dm-3 (Br-), 〉 60 mg dm-3 (Fe) and 〉 300 mg dm-3 (DOC) detected in some samples after rewetting, compared with typical values 〈 0.05 mg dm-3 (Br-), 〈 1 mg dm-3 (Fe) and 〈 15 mg dm-3 (DOC) under the drained conditions. Bromide, Fe and DOC release were highly seasonal, with the largest concentrations observed in late-summer to autumn. However, whereas seasonal peak concentrations of Fe and DOC have since remained at these higher levels, seasonal peak concentrations of Br- were progressively attenuated over time, suggesting the latter phenomenon is a flush effect, with no longer-term consequences for water quality.

    The cost of living, threshold bargaining and incomes policy1 (1973)
    Oxford, UK : Blackwell Publishing Ltd
    Industrial relations journal 4 (1973), S. 0

    Topics: Economics
    Notes: For trade union bargainers one of the infallible laws of political economy is that wages lag behind prices. This means that in an inflationary era the real value of the wage to which their members are entitled will be eroded, and some compensation will have to be made for this at the next round of wage negotiations. Therefore, changes in the cost of living since the last settlement will be regarded by trade unions as one of the most important factors to be taken into account in arriving at a new settlement. This is implicit in the statement made by the TUC in 1971 that “it requires pay increases of at least 10 per cent simply to restore the real disposable pay of a union's previous settlement 12 months earlier”. Economists, on the other hand, argue that once an inflation is under way, then economic agents will develop an inflationary psychology—that is, they will expect it to continue and will adjust their behaviour accordingly. If this is correct, trade union bargainers will attempt to anticipate inflation by trying to fix the money wage at a higher level than they would aim for if the price level were more stable.

    Using Thermal-Infrared Imagery to Delineate Ground-Water Discharge (1996)

    Ground water 34 (1996), S. 0

    Topics: Energy, Environment Protection, Nuclear Power Engineering , Geosciences
    Notes: On March 8 and 9, 1992, a thermal-infrared-multispectral scanner (TIMS) was flown over two military ordnance disposal facilities at the Edgewood Area of Aberdeen Proving Ground, Maryland. The data, collected by the National Aeronautics and Space Administration, in cooperation with the U.S. Army and the U.S. Geological Survey, were used to locate ground-water discharge zones in surface water. The images from the flight show areas where ground-water discharge is concentrated, as well as areas of diffuse discharge. Concentrated discharge is predominant in isolated or nearly isolated ponds and creeks in the study area. Diffuse discharge is found near parts of the shoreline where the study area meets the surrounding estuaries of the Chesapeake Bay and the Gunpowder River. The average temperature for surface water, measured directly in the field, and the average temperature, calculated from atmospherically corrected TIMS images, was 10.6° C (Celsius) at the first of two sites.Potentiometric surface maps of both field sites show discharge toward the nontidal marshes, the estuaries which surround the field sites, and creeks which drain into the estuaries. The average measured temperature of ground water at both sites was 10.7° C. The calculated temperature from the TIMS imagery at both sites where ground-water discharge is concentrated within a surface-water body is 10.4° C. In the estuaries which surround the field sites, field measurements of temperature were made resulting in an average temperature of 9.0° C. The average calculated TIMS temperature from the estuaries was 9.3° C. Along the shoreline at the first site and within 40 to 80 meters of the western and southern shores of the second site, water was 1° to 2° C warmer than water more than 80 meters away. This pattern of warmer water grading to cooler water in an offshore direction could result from diffuse ground-water discharge. Tonal differences in the TIMS imagery could indicate changes in surface-water temperatures. These tonal differences can be interpreted to delineate the location and extent of ground-water discharge to bodies of surface water.

    Notes: The alluvial aquifer underlying and adjacent to the Mojave River near Barstow, California, has been subjected to degradation from percolation of industrial and municipal wastes for more than 60 years. Effluents discharged to the aquifer have contained high concentrations of both organic (detergents, oil and grease, phenols, humic compounds, and others) and inorganic (chromium, chloride, phosphates, and others) substances. The concentration of dissolved organic carbon (DOC), as determined by a wet combustion technique, has been shown to be a definitive parameter in identifying ground water affected by waste disposal. DOC concentrations ranged from 0.1 to 0.8 milligram per liter in the nondegraded ground water and exceeded 6 milligrams per liter in the ground water affected by the waste discharge.The general distribution of DOC in the degraded ground water has been defined both areally and vertically. The vertical distribution of DOC and other constituents indicates that two plumes of degraded water occur at different depths. A comparison of the areal distribution of DOC and detergents (as MBAS) suggests that some organic compounds may have been adsorbed by the aquifer sediments.

    MODELING A CONCRETE BLOCK IRRIGATION DIVERSION SYSTEM (1998)

    Notes: : Concrete block irrigation diversion systems have been proposed as alternatives to permanent dams of concrete or rock or temporary gravel berms. Permanent dams can cause stream channel instability, bank erosion, sediment pollution, ice flow blockage, and safety problems for recreational floating craft. Temporary berms can require substantial streambed disturbance and can promote sediment pollution, stream bank instability, and bank erosion. A design procedure was developed based on a model of the hydraulic performance of concrete block diversion systems. The procedure was used to model a site on the Gallatin River in Montana. The method relies on HEC-RAS (Hydrologic Engineering Center -River Analysis System) software combined with analytical techniques in an iterative scheme. The hydraulic performance of different diversion configurations (the existing heavy-rock diversion system, concrete blocks oriented parallel to flow, and concrete blocks oriented diagonally) was assessed using the model under a range of flow rates. The minimum diversion dimensions (length, number, and size of blocks) that maintained block stability while diverting the requisite flow were determined for each model run. At the Gallatin River site, the block system oriented parallel to flow required less diversion material than the diagonal orientation. The recommended diversion length was 51.8 m (170 ft). Trapezoidal blocks with a top width of 20.3 cm (8 in), a height of 45.7 cm (18 in), and side slopes of 2 vertical to 1 horizontal were specified. This configuration minimizes the total block mass, diverts the required flow, and has a factor of safety of 2.0 against block displacement.

    Notes: This feature is in three parts: the first two are case histories of the contrasting experiences of two Western companies which expanded abroad for the first time in the mid-1990s, into different countries in Eastern Europe. One is so far successful, the other not. The third section draws out the implications of these experiences: although still quite risky, investment in Central and Eastern Europe can already be made to pay by firms that enter as part of a well-conceived and financed global strategy. Particular benefits are lower labour costs and access to untapped markets.
