Glacial Icemelt in the Wind River Range, Wyoming
The Wind River Range of Wyoming contains the greatest concentration of glaciers in the American Rocky Mountains with two of the larger glaciers being Dinwoody and Gannett Glaciers. This...
Rehabilitation and Modernization of Irrigation Projects is Often a Cover-up for Poor Quality Construction and Maintenance
Decreasing land and water resources available for irrigation projects is placing greater empasis on rehabilitation and modernization of irrigation projects. Inferior quality of the initial...
Understanding Delivery Performance Before Rehabilitation
In the initial stages of project formulation, decisions are made regarding the method for allocating water, and the method for physically distributing water. Any major rehabilitation effort...
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....
Evaluating Groundwater Pollution Potential Using Geographical Information Systems
A procedure for developing groundwater pollution potential maps using a geographical information system (GIS) is introduced. The concept of pollution potential mapping is discussed, along...

Competition for Water in Southern Nevada - Local Needs Versus Federal Control
The impacts of lands in southern Nevada, withdrawn by the federal government for defense and defense-related purposes on the water supply, are discussed. Nevada is an illustration of an...
Drainage Manual for Clark County, Nevada
The development of a flood control district and its associated capital improvement and regulatory programs does not by itself address drainage standards for a community. While the capital...
Way Against Debris Flows at China's Mountain Towns
For important protected objectives, the measures against debris flow in mountain towns should ensure all-round reliability and adopt a comprehensive system of engineering projects combined...
Complex Geomorphic Response to Minor Climate Changes, San Diego County, CA
Precipitation in San Diego County, California over the past several hundred years has been characterized by excursions between periods of relatively low precipitation having durations...
A Value Engineering/Risk Analysis Approach to Operation and Maintenance of Hydraulic Structures
Value engineering is an objective, systematic method for minimizing cost of a system. Risk analysis is a method of quantifying uncertainties or probabilities of possible economic loss,...
Field and Model Studies of Ocean Outfalls
Field and laboratory studies of the behavior of wastewater discharged from the San Francisco ocean outfall are reported. Wastefield behavior was predicted by the mathematical models RSB...
Task Committee on Transport Processes at the Interface of Water Column and Bottom Sediment
The Task Committee on Transport Processes at the Interface of Water Column and Bottom Sediment was formed on October 1, 1989 under the Technical Committee on Hydrologic Transport and Dispersion...
Identification Techniques for Bank Erosion and Failure Processes
The Hydraulics Laboratory of the US Army Engineer Waterways Experiment Station (WES) has developed techniques to design small flood-control channels. A component of this research is the...
Optimal Design of Highway Drainage Structures
Hydraulic design of a bridge or culvert using a risk-based approach is to choose among the alternatives the one associated with the least total expected cost. In this paper, the risk-based...
Conservativeness in Hydraulic Engineering Studies
Hydraulic engineers routinely make a variety of assumptions during the course of a study. Assumptions, once made, usually become incorporated into the fabric of the study and are seldom...
Stability Criteria for Revetments
A simplified 'black box' approach is presented for a number of revetment systems for banks and shore protection. The design criteria, based on the physical similarity...
The Sediment Weighted Histogram Generator and Estimation of Sediment Transport Trends
Long term sediment transport trends may be evaluated using a sediment histogram generator program that was written for microcomputers. Flows can be extracted directly from a compact disc...
Operational Model Development for Salinity Control
The 800 km2 Breton Sound estuary and watershed in Louisiana is being modeled to characterize its salinity regime in terms of hydrometeorological...
Status and New Capabilities of Computer Program HEC-6: Scour and Deposition in Rivers and Reservoirs
Last year the Hydrologic Engineering Center (HEC) and the Waterways Experiment Center (WES) incorporated the results from more than ten years of research and development into a new version...
