Optimization, Simulation and Multiobjective Analysis of Operating Rules for Reservoir Systems
In this paper, three steps are proposed for establishing reservoir operating rules which can be used in real-time without flow forecasting. In the first step, optimization models are used...
Oxygenation of Releases from Richard B. Russell Dam
The oxygen injection system at the Richard B. Russell project has a continuous injection system located 1 mile upstream of the Russell damsite but also has supplemental injection capability...
A Perspective on Performance Variability in Municipal Wastewater Treatment Facilities
Excessive variability in effluent quality can cause wastewater treatment plants to fail to meet their discharge permit limits. This paper summarizes our understanding of the nature, causes,...
The Reliability of Treatment Systems
The purpose of this paper is to present the results of case studies of zero and first order reactor systems and an activated sludge treatment system consisting of a primary settling tank...
Computer-Aided Analysis of Treatment Plant Hydraulics
This paper describes software for the hydraulic analysis of water and wastewater treatment works. HADES (the Hydraulic Analysis, Design, and Evaluation System,) provides interactive analysis...
Regional Detention Basins as a Flood Control Solution
Through engineering studies the Harris County Flood Control District (HCFCD) has identified a feasible regional flood control project which can be constructed with local funding and would...
Financing Water Supply Infrastructure - A Public Works Perspective
The Massachusetts Water Resources Authority was established to ensure that the regional water and wastewater needs were properly addressed, removing the budget process from the legislature...
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...
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...
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...
Engineering and Policymaking: The Platte River in Nebraska
Substantial conflict exists over proposed water projects in the Platte River Basin of Nebraska. A computer simulation model, representing the engineering and environmental dimensions of...
Community Relations on Hazardous Waste Projects: A Successful Experience
Promoting good community relations is an integral part of hazardous waste projects. Before field investigations are conducted at a hazardous waste site, neighboring communities should...
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...
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...
Intense Storms and the Runoff Coefficient
During prolonged, intense storms the runoff coefficient increases in value and approaches one irrespective of the vegetation and soil characteristics of the watershed. As the runoff coefficient...
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...
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...
