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...

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...

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...

Land Management and Water Yield in the Appalachians
Watershed treatments on the Fernow Experimental Forest have included individual tree selection, commercial clearcutting, clearcutting upper and lower halves of watersheds, clearcutting...

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...

Fish Bypass Facilities - Tehama-Colusa Canal
Operation of the canal headworks has proven to be detrimental to migrating fish passing the Red Bluff Diversion Dam. Studies performed for the U.S. Bureau of Reclamation were undertaken...

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....

Comparison of ET Measured with Neutron Moisture Meters and Weighing Lysimeters
The neutron moisture meter (N.M.) method of determining crop water use is frequently used in research and irrigated agriculture. This study was conducted to compare crop evapotranspiration...

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...

Influence of Method of Fertilizer Application on Groundwater Pollution
Researchers at New Mexico State University have been looking for methods to improve the efficiency of fertilizer application in irrigated agriculture. Preliminary results obtained in the...

Treatment, Reuse and Disposal of Drain Waters
Treatment, reuse and disposal options of agricultural drainage water present formidable technical problems. Various treatment technologies and disposal methods have been studied. Reuse...

Movement of Triazine Herbicides and Metolachlor in a Sandy Soil
The movement of atrazine, cyanazine, simazine, and metolachlor was studied in an Evesboro loamy sand soil. Both no-tillage and conventional tillage treatments were used. Atrazine, simazine,...

Nonpoint Source Pollution from Agricultural Drainage: Impacts and Innovations in California
This paper provides an overview of the more significant impacts of agricultural drainage in California, and describes the role of the State's Agricultural Drainage Water Management...

Implemented Solutions to Wqter Supply Problems?The Tucson Experience
During the past 30 years Tucson Arizona has been one of the fastest growing urban centers in the United States. During this period, the population served by the municipal water utility,...

Future Transfers of Water and Conveyance Capacity Between the CVP and the California SWP
On November 24, 1986, the Bureau of Reclamation (USBR) and the California Department of Water Resources (DWR) executed an agreement known as the Coordinated Operations Agreement or COA....

Arid Zone Hydrologic Implications for the Proposed Yucca Mountain Repository
The U.S. Department of Energy (DOE) has chosen Yucca Mountain, Nevada for characterization to determine if it is suitable to become the Nation's first High-Level Radioactive...

Chemically-Enhanced Treatment: An Alternative to Biological Secondary Treatment for Ocean Outfalls
Chemically-enhanced treatment is a process whereby chemicals are added to wastewater in order to enhance solids removals through coagulation. This treatment process can obtain removal...

Iona Outfall Plume Characterization Study
Field studies were conducted in August 1988 to verify the performance of the new deep sea outfall for the Greater Vancouver Regional District (GVRD) Iona Island Sewerage Treatment Plant...
