Oilcrete
Threatened by probable tightening of hazardous-waste legislation, oil companies are searching for ways to dispose of or stabilize oil-drilling byproducts. One way is cementitious stabilization...
Stopping Waste at the Source
Contrary to popular belief, waste reduction at the source, rather than end-of-the-pipe waste treatment may the nation's best approach to the hazardous waste problem. Surprisingly,...
Bay-Wide Model Studies for the Boston Ocean Outfall Siting
Oceanographic data and numerical models were used to evaluate candidate diffuser sites to discharge effluent from Boston's planned secondary treatment plant. The study showed...
Multidisciplinary Hydrologic Investigations at Yucca Mountain, Nevada
Future climatic conditions and tectonic processes have the potential to cause significant changes of the hydrologic system in the southern Great Basin, where a nuclear-waste repository...
Natural System Issues in the OCRWM Program
Twenty four site characterization Issues, most of which pertain to the natural system, are presently defined in the Office of Civilian Radioactive Waste Management (OCRWM) Program for...
High Level Radioactive Waste Management 1990
The proceedings of the first annual Conference on High Level Radioactive Waste Management, held on April 8-12, 1990, Las Vegas, Nevada, provides information on the current technical issues...
Bridges Under Surveillance
Although bridge monitoring is still in its infancy, research, pilot studies and field work are underway across the country. While today it's still a pie-in-the-sky goal, the...
A Method for Estimating Peak Flows from Small Agricultural Watersheds
An attempt was made to develop a method for estimating peak runoff from agricultural watersheds by analyzing precipitation and runoff data, and incorporating the results into a procedure...
Method to Predict Cropland Ephemeral Gully Erosion
Erosion of farmlands due to concentrate flow is very severe on many unprotected fields across the county. Small channels can you in large gullies of not controlled. These small channels...
Soil Moisture Measurements in Oil Shale Waste Material Using a Neutron Probe and Time Domain Reflectometry
Five large scale lysimeters (7.3 ? 3.0 ? 3.0 m deep) have been constructed to collect information and data on hydrological factors which affect the movement of water through a large scale...
Optimizing Wet-Dry Precipitation Probabilities for Improving Plant Establishment
Studies have shown that the chances of achieving successful seedling establishment in arid and semiarid regions is dependent upon the pattern of favorable wet-dry precipitation sequences....
AGNPS: A Tool for Watershed Planning
The AGNPS model was developed to provide a means of assessing water quality impacts from agricultural watersheds. AGNPS simulates sediment and nutrient transport from the headwaters to...
Supplemental Irrigation by Runoff Farming: An Economic Assessment
A simulation model was used to evaluate the economic potential for using runoff farming techniques for growing grain sorghum at two locations in Texas. The results show that the yearly...
Modeling Erosion and Effects of Agricultural BMP's on a West Tennessee Watershed
The application of Hydrological Simulation Program FORTRAN (HSPF) to nonpoint source data was examined. The model is used to determine the effects of land management practices upon surface...
Measurement of Irrigation Water Use: Results of Two Case Studies in Illinois
Three methods of measuring and estimating irrigation pumpage were used during two research studies attempting to assess ground-water use. These three methods: (1) farmer estimates; (2)...
Research Needs in Movement of Agricultural Chemicals to Groundwater
Better prediction of the movement of agricultural chemicals to groundwater is necessary to permit development of best management practices to reduce adverse environmental effects of agriculture....
Neutron Meters in Statewide Irrigation Programs
These programs have ranged from University demonstrations of new technologies on through completely locally funded and operated programs. The most significant interest has been from those...
Delivering Appropriate Quantities of Water to the Farm
To study how well an irrigation district was able to meet farmer demand, water deliveries along two monitored lateral canals were compared to the orders and bills for these events. The...
Problems with Irrigation Technology Transfer in Latin America
Over the last thirty years there has been a significant drop in agricultural production in Latin America, despite the fact that agricultural, irrigation and drainage projects receive about...
Impact of Agriculture on Ground-Water Quality on the Delmarva Peninsula
Both pesticides and nitrates have been detected in the ground water on the Delmarva Peninsula. Highest nitrate concentrations have been found on well-drained soils. Poultry manure is one...
