High Recovery Desalting Of Brackish Water By Electrodialysis: Field Tests At Yuma Desalting Test Facility & At La Verkin Springs, United States Department Of The Interior, Bureau Of Reclamation
High Recovery Desalting Of Brackish Water By Electrodialysis: Field Tests At Yuma Desalting Test Facility & At La Verkin Springs, United States Department Of The Interior, Bureau Of Reclamation
Water
An ED (electrodialysis pilot plant achieved high desalting recoveries of nearly 95 percent at the YDTF (Yuma Desalting Test Facility, Arizona) and 92 percent at LVS (La Verkin Springs, Utah) during over 4000 hours of operation. Brine TDS (total dissolved solids) concentrations of nearly 100 000 g/m3 were obtained at LVS, which is a greater brine concentration than is possible using RO (reverse osmosis). The LVS required ED energy (while producing a product TDS concentration of about 1000 g/m3) is estimated to be about one-third the energy requirements of a commercially available distillation brine concentrator. Lowering product …

Plant Available Water And Plant Water Stress, Ronald E. Phillips
Soil Science News and Views
The 1983 growing season in Kentucky was a vivid reminder that water is essential for good plant growth. And the water used by plants is taken from the reserve or water stored in soil.

Sewage Sludge For Land Application, William O. Thom
Soil Science News and Views
Sewage sludge is a product of waste water treatment plants that function as environmentally acceptable pollution control facilities. In past years most of the sludge had been landfilled, dumped at sea or buried. But environmental and economic considerations have resulted in greater interest in its application on cropland.
The Historical Development Of The Yakima-Tieton Irrigation District And Its Present Effect On Life In The Area Encompassing The District, Werner E. Lemke
The Historical Development Of The Yakima-Tieton Irrigation District And Its Present Effect On Life In The Area Encompassing The District, Werner E. Lemke
All Graduate Projects
Irrigation played a very important role in the development of the Yakima Valley as we know it today. The Yakima-Tieton Irrigation District was chosen to show how an irrigation system functions and the part it plays on the lives of the plants, animals and people in its area. A brief historical study of the Tieton Division of the Yakima Project was made. The construction of the Tieton Unit was studied. A slide lecture with an accompanying tape was developed to acquaint junior high school students with the purpose, function and affects of the Yakima-Tieton Irrigation District.
Effect Of Small Aspen Clearcuts On Water Yield And Water Quality, United States Department Of Agriculture, Forest Service
Effect Of Small Aspen Clearcuts On Water Yield And Water Quality, United States Department Of Agriculture, Forest Service
Forestry
Streamflow and water quality were monitored in a paired watershed study involving the removal of 20 percent of the aspen (on 13 percent of the area) in five small clearcuts from a 217-acre (88-ha) catchment. There were no significant changes in peak flow, timing, or annual yield during the 4 years of posttreatment monitoring. Significant changes in pH, calcium, magnesium, and nitrates in the snowmelt streamflow from ephemeral subdrainages occurred the second year after cutting. At least some of the differences were attributed to the chemistry of the 1976-77 snowfall, which was also significantly different from snow sampled in the …

Water Erosion On Potato Land During The 1983 Growing Season Donnybrook, D J. Mcfarlane
Resource management technical reports
Soil losses over a three month period varied from 10 to 49 mm.. Soil loss was most highly correlated with length of slope of the plots. Other important factors appeared to be slope angle and soil textures. Grade furrows appear to be the best method of breaking-up long slope lengths. The low capacity of the furrows requires them to be on grades of about 4 to 4 per cent to prevent siltation and overtopping during high density storms.
