Response To Freshwater Inflow In The Rappahannock Estuary, Virginia : Operation Hiflo '78, Maynard M. Nichols, L. Eugene Cronin, William B. Cronin, M. Grant Gross, Bruce W. Nelson, Jack W. Pierce, Robert E. Ulanowicz

Reports

More sediment, nutrients and pollutants are discharged into an estuary during a few days of flood inflow than during many months or years of average inflow (Meade, 1972; Schubel, 1977), but few observations document the sedimentary response of an estuary to high freshwater inflow. Such inflows are usually unexpected and estuarine water charact~ristics change too rapidly to permit systematic measurements. Moreover, the expenditure of effort and number of sampling vessels required on short notice is beyond the resources of a single research group or institute. Yet, freshwater inflow observations are a key to improving water quality; especially to ameliorate the …


Landsat Analysis Of The Dynamics Of The Chesapeake Bay Plume On The Continental Shelf, John C. Munday, Michael S. Fedosh Apr 1981

Landsat Analysis Of The Dynamics Of The Chesapeake Bay Plume On The Continental Shelf, John C. Munday, Michael S. Fedosh

Reports

The dynamics of the Chesapeake Bay plume have been studied by examination of 81 dates of Landsat images with color additive enhancement and single-band density slicing. The "plume" was interpreted from surface turbidity discontinuties as revealed in images from multispectral scanner (MSS) bands 4-7. Results show that the Chesapeake Bay plume usually frequents the Virginia coast south of the Bay mouth. Wind and tide vectors are the principal variables affecting the plume dynamics. Southwestern (compared to northern) winds spread and disperse the plume easterly over a large area. Ebb tide images (compared to flood tide images) show a more dispersed …

Update On Estimation Of Water Surface Elevation Probabilities For The Great Salt Lake, L. Douglas James, David S. Bowles, W. Robert James, Ronald V. Canfield

Reports

The techniques of operational hydrology, employing an autoregrssive moving average (ARMA (1,0) model were used to replicate historical patterns of streamflow into, precipitation on, and evaporation from the Great Salt Lake. The results were combined with a lake water balance model to simulate lake stage sequences beginning with known initial conditions and extending up to 125 years into the future and used to generate probability distributions for future lake stages. Starting with a spring 1980 high stage of 4200.45 ft msl, the best estimate is that the 1981 spring high will be 4200.19, but there is one change in four …


Hydrosalinity Impacts Of Conservation Measures In The Sevier River Basin, Eugene K. Israelsen Jan 1981

Hydrosalinity Impacts Of Conservation Measures In The Sevier River Basin, Eugene K. Israelsen

Reports

The Sevier River Basin is a water short basin wherein upstream diversions not consumptively used become the water right for downstream users. The diversion-return cycle occurs several times as the stream travels from its mountain source areas to the terminal lake at the lower end of the basin. This study dealt with the proposed implementation of conservation measures which would wawste less diverted water and allow for irrigation of additional acres. The objective was to predict the hydrosalinity impacts of the implementation of these measures. The results indicated that increased consumptive use in the upper areas would decrease the water …

Calcium Carbonate Precipitation As Influenced By Stream Primary Production, Gretchen L. Rupp, V. Dean Adams Jan 1981

Calcium Carbonate Precipitation As Influenced By Stream Primary Production, Gretchen L. Rupp, V. Dean Adams

Reports

The potential influence of periphyton photosynthesis on calcium carbonate precipitation was studied for the Logan River, Bear River Mountains, northern Utah. The water chemistry, hydrology, and benthic primary production of the river were monitored for one year. periphyton photosynthesis and calcium carbonate precipitation were measured concurrently in laboratory experiments utilizing radioisotopic tracers. These experiments investigated the effects of water temperature, velocity, and macronutrient concentration on photosynthetically induced calcium carbonate precipitation. In these experiments, the biologic induction of calcium carbonate precipitation was not correlated with water nutrient level. It did, however, reflect water temperature, and was greatest at approximately 10 degrees …

Natural Salinity Removal Processes In Reservoirs, Jay J. Messer, Eugene K. Israelsen, V. Dean Adams Jan 1981

Natural Salinity Removal Processes In Reservoirs, Jay J. Messer, Eugene K. Israelsen, V. Dean Adams

Reports

A small but significant amount of salinity removal has been reported by various authors to occur in mainstem Colorado River reservoirs. Recalculation of some of these salinity budgets, together with a review of the data bases used, usggests taht removal has not often been conclusively demonstrated. Laboratory microcosm experiments and field data indicate that calcium carbonate precipitation, perhaps with some coprecipitation of magnesium carbonate, is the mechanism responsible for most of the salinity removal in Oneida Reservoir, Idaho. Coprecipitation processes (including ion exchange), coagulation, and bioassimilation do not appear to be important natural salinity removal mechanisms. Finally, loss of calcium, …

Design Considerations In The Use Of Glauber Salt For Energy Storage, Duane G. Chadwick, Kim H. Sherwood Jan 1981

Design Considerations In The Use Of Glauber Salt For Energy Storage, Duane G. Chadwick, Kim H. Sherwood

Reports

Various design concepts for the utilization of the latent heat of Glauber salt at temperatues between 25 degrees C and 50 degrees C were studied. Consideration was given to system economics and what particular heat storage system if perfected would be most cost effective. The problems of limited crystal size and heat transfer into and out of salt crystals is discussed. Crystal size is affected by the degree of agitation the salt solution experiences during the salt cooling process. Consequently, crystal size was moderated in a favorable way by introducing air bubbles at the bottom of the salt container. As …

Economic Impacts Of Irrigation Technologies In The Sevier River Basin, Theodore R. Frickel, Rangesan Narayanan Jan 1981

Economic Impacts Of Irrigation Technologies In The Sevier River Basin, Theodore R. Frickel, Rangesan Narayanan

Reports

The economic well-being of the semiarid intermountain area requires efficent use of available water supplies. Agriculture, the major water-consuming industry, depends on irrigation water. The adoption of sprinkler systems that increase on-farm irrigation "efficiencies" and the area which can be irrigated from upstream diversions may interfere with the "tenure" of downstream water rights. These downstream effects need to be evaluated before allowing farmers to use the water "saved" to irrigate additional acreages or crops to obtain greater profits. The problem in letting farms expand their irrigated acreage is that the individual farmer increases his profits through increased consumptive use. The …
