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The impacts of lands in southern Nevada, withdrawn by the federal government for defense and defense-related purposes on the water supply, are discussed.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...
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...
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...
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...
Municipal Stormwater Management Ordinance Development and Implementation in Pennsylvania
This paper discusses the critical planning and engineering components of a sound stormwater management ordinance and how they can be shaped to avoid commonly encountered basin-wide implementation...
Use of Linear Programming for Hydraulics Problems
Water is becoming a more and more precious commodity worldwide with each passing day. At the same time, the optimum and most productive solutions to water control and utilization are becoming...
Pump Selection Program and a Better User Interface
Numerous highly innovative computer solutions to engineering problems are of little use to the practicing engineer because these programs are not supported by adequate user interface....
Coronarization of the Autonomous Water pump
The conventional hydraulic pressure multiplier has been successfully used by Belgian technician Robert Houman (1986) to provide a dependable source of water supply to the NATO-base at...
Grid-Induced Errors in Depth-Averaged Flow Fields
A computer code called CH2D (Curvilinear Hydrodynamics in Two Dimensions) for computing depth-averaged free-surface flow fields has been used to assess the impact of the rate of change...
Effects of Tide on Variation of Beach Profile
Effects of tide on variation of beach profile are examined experimentally. It is clarified that tidal effect appears differently when it acts on beach of different profiles. Namely, in...
Mechanical Aspects of Intake Gates at John Hart Dam
As part of the John Hart Dam rehabilitation program completed in 1988, six new intake gates complete with guides and hydraulic operators were installed replacing the existing gates and...
Corps of Engineers Sediment Management Program
The existing sediment management program includes sediment investigations of reservoir, river and levee projects; gathering and maintaining sediment load records; providing sediment investigation...
Major Sedimentation (Erosion) Issues and Ongoing Research and Developments at the USDA-ARS
The U.S. Department of Agriculture, Agricultural Research Service (ARS) has research programs designed to produce techonology with which to predict, measure, and control erosion and sedimentation...
