    UNDERWATER PHOTOGRAMMETRY IN THE NORTH SEA (1983)
    Oxford, UK : Blackwell Publishing Ltd
    The @photogrammetric record 11 (1983), S. 0 
    Details
    ISSN: 1477-9730
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Architecture, Civil Engineering, Surveying
    Notes: Underwater photogrammetry is being used in the particularly hostile environment of the North Sea where it has been put into commercially viable operation. The authors discuss underwater photogrammetry related to other means of inspection of oil platforms. They also deal with operational experience of 35 mm and 70 mm cameras, camera calibration, the provision of control and photogrammetric observations and data analysis. The demand for underwater photogrammetry continues to grow.

    A CHLORIDE BUDGET FOR THE MISSISSIPPI RIVER, HEADWATERS TO MOUTH (1984)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of the American Water Resources Association 20 (1984), S. 0 
    Details
    ISSN: 1752-1688
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Architecture, Civil Engineering, Surveying , Geography
    Notes: Mass budgets for chloride were estimated from 1975-1978 for the Mississippi River from headwaters to near the mouth to determine the magnitudes of natural and anthropogenic sources. Annual chloride input from precipitation ranged from about 200 kg mi-2yr-1 at Royalton, Minnesota, to about 350 kg mi-2yr-1 at Vicksburg, Mississippi. Mass export ranged from about 900 kg mi-2yr-1 at Royalton to about 8000 kg mi-2yr-1 at Vicksburg. As much as 80 percent of the residual, the difference between input and export, probably is contributed by anthropogenic sources. In particular, semi-logarithmic scatterplots of monthly total discharge against chloride concentration show that, during early spring, chloride elevations in the Mississippi River and Ohio River are elevated, possibly because of flushing of road salt and leaching of chloride from the accumulated snowpack.

    THE STABILITY IN WATER OF A NEW CHLORAMINE DISINFECTANT AS A FUNCTION OF pH, TEMPERATURE, AND WATER QUALITY (1984)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of the American Water Resources Association 20 (1984), S. 0 
    Details
    ISSN: 1752-1688
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Architecture, Civil Engineering, Surveying , Geography
    Notes: The stabilities in water and dry storage of two solid-state disinfectants (3-chloro-4, 4-dimethyl-2-oxazolidinone, agent I, and calcium hypochlorite) have been compared under a variety of conditions. Variables in the study included pH, temperature, and water quality. Agent I is considerably more stable in dry storage and in water, especially at pH 4.5 and 7.0, than is calcium hypochlorite. This is true for solutions of the two compounds in sterile, distilled, deionized, demandfree water or in a synthetic water containing heavy organic load. Prior work in these laboratories concerning use of agent I as a disinfectant for lake water in a laboratory-scale treatment plant had suggested that agent I has considerable potential for use as an alternative to cholorine gas for water disinfection. The present work suggests that agent I is of sufficient stability to be of use as a solid-state disinfectant for swimming pools and for potable water for remote areas.

    THE TENDENCY OF A NEW WATER DISINFECTANT TO PRODUCE TOXIC TRIHALOMETHANES (1984)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of the American Water Resources Association 20 (1984), S. 0 
    Details
    ISSN: 1752-1688
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Architecture, Civil Engineering, Surveying , Geography
    Notes: A new organic N-chloramine disinfectant (3-chloro-4, 4-dimethyl-2-oxazolidinone, agent I) has been compared with calcium hypochlorite as to its tendency to react with organic matter in water to produce toxic trihalomethanes. Agent I reacts much less readily with organic demand than does calcium hypochlorite. This study shows that agent I should be safe to use as a disinfectant for water containing appreciable organic load in either sunlight or darkness. On the other hand, calcium hypochlorite may not be a satisfactory disinfectant from the toxicity standpoint for water which contains organic load which must be stored for extended time periods in either sunlight or darkness.

    A NOVEL CHLORAMINE COMPOUND FOR WATER DISINFECTION (1981)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of the American Water Resources Association 17 (1981), S. 0 
    Details
    ISSN: 1752-1688
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Architecture, Civil Engineering, Surveying , Geography
    Notes: A new chloramine agent, 3-chloio-4, 4-dimethyl-2-oxazolidinone, has been tested in a laboratory scale water treatment plant as to its efficacy in water disinfection. The agent seems to be equally effective as compared to chlorine gas in this application. The results of preliminary toxicity studies on the agent are very encouraging. The agent has a long shelf life both in water solution and in the solid state. Being a solid, the agent is clearly less hazardous to handle than chlorine gas. The agent appears to inhibit oxidative corrosion of metals as well. The agent is less likely to produce toxic halocarbons (e.g., chloroform) in water than is chlorine gas. Possibly most important from the standpoint of water disinfection, the agent is a “slow release” one for its positive chlorine, which provides prolonged bactericidal activity.

    THE STABILITY IN WATER OF A NEW CHLORAMINE DISINFECTANT (1983)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of the American Water Resources Association 19 (1983), S. 0 
    Details
    ISSN: 1752-1688
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Architecture, Civil Engineering, Surveying , Geography
    Notes: : The stability in water of a novel new chloramine agent, 3-chloro-4, 4-dimethyl-2-oxazolidinone (agent I), which is an excellent water disinfectant, has been compared to the stabilities of several other water disinfectants. The agents tested in addition to agent I included N-chlorosuccinimide, 2, 4-dichloro-5, 5-dimethylhydantoin, tichloroisocyanuric acid, calcium hypochlorite, commercial grade HTH, and household bleach. The total chlorine content of a water solution of agent I in a demand free environment remains constant over a period of at least eight weeks, while that for all of the other agents declines markedly over that time period. An explanation for these observations will be offered. Prior work in these laboratories concerning use of agent I as a disinfectant for lake water in a laboratory scale treatment plant had shown that agent I has considerable potential for use as an alternative to chlorine gas for water disinfection.

    PHYSICAL PROCESSES AND EUTROPHICATION (1982)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of the American Water Resources Association 18 (1982), S. 0 
    Details
    ISSN: 1752-1688
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Architecture, Civil Engineering, Surveying , Geography
    Notes: : Biological responses to physical-chemical processes were examined in Toronto and Hamilton Harbours of Lake Ontario. Nutrient loadings to the harbors are large and are of similar magnitude, yet the trophic conditions of the harbors were considerably different. Lake oscillations were found to determine the flushing rates and environmental stability of the harbors. LOW residence times (〈10 days) resulted in homogenous chemical conditions in Toronto Harbour, and prevented the establishment of large phytoplankton crops. The longer retention time of Hamilton Harbour permitted the establishment of huger phytoplankton crops. There probably exists a critical retention time where nutrient input events persist for a sufficient period of time for the algal community to adapt to and exploit the environmental conditions of nearshore areas.

    Notes: Dye tracers have been used in Oregon in the Collection of hydrologic data on 2,350 miles of stream channels in the Long Tom, Umpqua, Willmette, and John Day River basins, and in the Carmen-Smith power tunnel. These investigations demonstrated the usefulness, of dye tracers for determining: (1) estimates of traveltimes and travel rates of water, (2) discharge where standard methods of measuring are not applicable, and (3) dispersion characteristics of streams. Illustrations are used to present the results of time-of-travel studies in simple, concise, and readily interpreted form.

    Notes: The literature was reviewed in order to determine the variables likely to be important in forecasting thunderstorms. A stepwise discriminant analysis was performed on these variables to determine those significantly related to thunderstorm occurrence. Eight variables were selected. These were then used to produce a forecasting equation by means of the linear discriminant analysis technique. This equation was then tested against the Showalter and Total Totals indexes for forecasting skill, and was found to have higher skill.
