Development of the Hydrology Criteria Manual for Harris County, Texas
The Harris County Flood Control District (HCFCD) was created in 1937 with the primary objectives of reducing potential damages from flooding in the Harris County area and of providing...
Potential Non-Traffic Benefits from a New Highway
The State of Delaware is now in the design/build phase of a major north-south relief highway. Expedient action included an Environmental Impact Statement adequate to show that the project...
Groundwater Loadings of Pesticides From Chemigation: A Gleams Model Simulation
This paper describes how, with slight modifications, the GLEAMS model (Groundwater Loading Effects of Agricultural Management Systems) was used to represent chemigation for herbicides,...
Agricultural, Meteorologic, and Hydrologic Drought Relations: Applications to Irrigation and Water Supply Planning
Meteorologic and hydrologic factors can combine to significantly reduce crop yields, leading to an agricultural drought. Agricultural and hydrologic droughts affect a large segment of...
The Water Erosion Prediction Project: Erosion Processes
The erosion process on hillslopes is conceptualized in the USDA Water Erosion Prediction Project (WEPP) as being divided into rill and interrill processes. Rill detachment occurs when...
Locating and Sizing Air Release Valves on Irrigation Systems
This writing is directed to persons involved in irrigation systems and describes the usage of air release and vacuum valves. Principles described are applicable to many other piping systems,...
Dam Replacement Insurance
Most dam owners recognize that the dams they operate are critical structures, both to water users as well as downstream floodplain occupants. Loss of the structure use has significant...
Water Resources Planning for the San Antonio Region
Water resources planning for the San Antonio region begins with the physical setting and the technical considerations - the science and engineering aspects. It proceeds to the economic...
World Bank's Role in Global Water and Related Environmental Issues
The World Bank provides loans and technical assistance to developing countries for improvement of the physical and economic well-being of the people. A major portion of its lending is...
Conflict Resolution in Regional Water Management
The experience with environmental dispute resolution (EDR) at South Florida Water Management has been largely one of changing the operating premises regarding the agency's...
Planning for Future Hydroelectric Power: A Myth?
The hydroelectric power industry in the U.S. is authorized and regulated by the Federal Government through the Federal Energy Retgulatory Commission (FERC) under the Federal Power Act....
Strategies for Planning Metropolitan Water Supplies
Metropolitan growth and increased concerns for water quality and environmental impacts have created challenges for the provision of water supplies within metropolitan areas. The paper...
Optimal Control of the West Parisian Area Water Supply Network
The West Parisian Area regional office of Lyonnaise des Eaux has been equipped with computer-aided optimal decision-making software, using daily water demand forecasts. This tool calculates...
Simulation Model for Economic Irrigation Project Planning and Design
The principle design parameters considered are: water supply configurations (quantity, source and storage); shapes and sizes of the area to be served; on-farm irrigation techniques; cropping...
The Los Vaqueros Model: A Microcomputer-Based Reservoir Planning System
This paper describes the development and application of a set of microcomputer models for the evaluation of a complex water resources project. The Los Vaqueros Model includes components...
Total Sediment Transport and Its Physical and Mathematical Modeling
Some main results in the field of sediment transport theories obtained by the author are presented. Based on these theories, the methods of physical and mathematical modeling for total...
Advances in Computational Mobile-Bed Hydraulics
A new conceptual approach to one-dimensional mobile-bed simulation is briefly described, along with two demonstrative examples. The approach is based on fully coupled solution of the unsteady...
Bed Waves Generated by Internal Waves in Alluvial Channels
The flow in an alluvial channel is conceived as a stratified flow both with respect to the velocity- and density-distribution. In such flows internal waves may occur which influence the...
Friction Slope Computation for Mathematical Models
The behavior of the energy flow gradient as function of depth and velocity is analyzed for three flow resistance methods. In the paper, the necessary modifications introduced to the methods...
Comparison of
Manning's n values were determined for three stream channels in two complex watersheds in North Mississippi. The study covered a wide range of channel conditions and flow...
