Water Infrastructure: Research and Education Needs
Problems with infrastructure have received considerable attention but not much has been written about implications for research and education. Education and research should be aimed at...
Verification of a Supply Reliability Model
Three versions of an analytical model for estimating the reliability of a water supply system including capacity components and small amounts of finished water storage are presented. Simplifying...
Drinking Water Distribution System Reliability: A Case Study
The purpose of this study was to present a tool useful to water utilities that not only could analyze historical distribution system reliability data, but also provide a flexible and expandable...
Hydraulic Reliability of Urban Water Distribution Systems
Conventional planning and design approaches for urban water distribution systems consist of trial and error procedures to select piping network configurations, pipe sizes, storage capacities...
Modeling Reliability in Water Distribution Network Design
The component failures in a water distribution system include pipe breaks, pump failures, valve failures, storage malfunctions, etc. The reliability of these components has an effect upon...
Model for Optimal-Risk Based Water Distribution Network Design
Various models using a variety of optimization techniques were developed for determining pipe diameters, network layout, pump capacities, and other design parameters. The objective function...
NID Water Supply and Hydropower Operation Model
A basic requirement of CH2M HILL's Raw Water Master Plan for Nevada Irrigation District (NID) was to determine the dependable water supply available from the District's...
Facilities Planning in the Caribbean a Case Study
Culebra has significant problems of water scarcity and poor wastewater treatment. In 1984-1985, a formal Environmental Impact Statement (EIS) was prepared for improved wastewater treatment...
Irrigation in Mexico
Mexico has a great historic tradition in the construction of works for irrigation; irrigated agriculture has been practiced since the pre-hispanic epoch. The development of hydro-agriculture...
Irrigation Development in Alberta, Canada
Agricultural production in the southwestern part of the Canadian prairie provinces is limited by insufficient rainfall for optimum crop production. To overcome this moisture deficiency...
Strategy for Ground Water Planning
Though the percentage of ground water development is only 40%, many areas of India are over developed, where water tables are falling rapidly, due to over pumping. In some areas the surface...
Colorado High Mountain Aquifer Study
This paper describes the potential for formulating water projects in Colorado using the storage capability of high mountain glacial aquifers. Although a terminal moraine provides a natural...
Hansen Dam Sediment Modeling Study Impact of Water Supply vs. Flood Control Operational Modes on Sediment Deposition in the Reservoir Area
The analysis of scour and deposition in Hansen Reservoir by modeling the interaction between the water-sediment mixture, sediment material forming the stream's boundary and...
Effects of Irrigated Agriculture on Groundwater Quality in the Corn Belt and Lake States
Irrigation of croplands has the potential to increase the rates at which water soluble substances are leached from soil into underlying aquifers. This paper evaluates the impact of irrigated...
Effect of Irrigated Agriculture on Ground-Water Quality in the Appalachian and Northeastern States
Irrigation acreage has more than doubled in Virginia, North Carolina, Delaware and Maryland in the last 10 years. Ground-water studies have been conducted in Delaware, Maryland and New...
Ground Water Pollution Potential from Irrigation?Eastern United States
The purpose of this paper is to present an evaluation method for determining the influence irrigation of agricultural land has on regional ground water quality. It integrates data on irrigation...
Impact of Irrigation on Groundwater Quality in Humid Areas
The GLEAMS Model (Groundwater Loading Effects of Agricultural Management Systems) was applied to estimate the effects of soil, planting date, irrigation level, and pesticide characteristics...
Interbasin Issues Related to Groundwater Management
This paper evaluates several options for settling disputes over sharing water and concludes in favor of well-conceived state compacts. More than other methods, such compacts offer continual...
