Risk Consideration in Water Supply Reservoir Capacity Design
This study develops a method for estimating the risk in reservoir capacity design by applying frequency analysis to the mass curve method. It provides a means for the engineer to use familiar...
Risk Management for Water Supplies During Droughts
This paper describes a method for deriving policies for the operation of public water supplies under impending and actual drought conditions. Unlike previous models based on optimization...
Determining Impacts of Sediment Using Cesium-137
Tecumseh Lake, in east-central Oklahoma, completed about 1934, has been identified by the Oklahoma Water Resource Board as a water supply critical to future development of the state. Aerial...

Water Distribution Systems Analysis Package
A computer software package for water distribution systems analysis has been developed for the city of Fort Worth, Texas, to overcome the problems of time consumption and human error,...
An Analysis of Hourly Water Use in Austin, Texas
While it is possible to calculate water use over a fairly short period of time, this only yields a single value for peak use. It does not give a comprehensive understanding of the frequency,...
Water Distribution Network Calibration Considering Multiple Loading Conditions
Through time a water distribution network's carrying capacity is reduced as material collects on pipe walls. The impact varies with each pipe in the system and occurs at an...
Methodology for the Optimal Reliability Based Design and Analysis of Pumping Systems for Water Distribution Networks
A methodology has been developed for the optimal (minimum cost) reliability based design of pumping systems. Two computer simulators, a reliability simulator and a hydraulic simulator,...
Optimal Pump Operation Using Nonlinear Programming
This paper focuses on the operational control problem of determining the optimal pump operation policy for a given distribution system. The optimal pump policy is defined as that schedule...
Trends and Emerging Issues: A Longitudinal Study of Government Agencies' Perceptions of Great Lakes Water Resources and Related Issues
The perceptions of government agencies with jurisdiction over Great Lakes' shoreline has changed over time with respect to important issues related to water quality and a...
Regional Assessment of Pumpage in Southeastern Virginia
A U.S. Geological Survey investigation was conducted, in cooperation with the Virginia Water Control Board, to analyze the hydrogeology and groundwater flow system in the Coastal Plain...
IWR-Main?Version 5.1?An IBM-PC or Compatible Water Use Forecasting System
The IWR-MAIN water use forecasting system is a sophisticated and flexible computer program designed for estimating and forecasting municipal water requirements. The IWR-MAIN system is...
CADD Applications in Water Resources Design
CADD can provide substantial benefits, in terms of speed and ease of revisions, in the design of civil engineering projects, including water resources facilities. However, current design...
Water Supply Critical Areas
Due to the serious overuse of groundwater resources which has led to the continued decline of the potentiometric surface of certain aquifers below sea level, and to real and potential...
Master Plan of a Reclaimed Water System
Arizona cities are under a state mandate to reduce water consumption as a result of the 1980 Arizona Groundwater Management Act. Since reclaimed water use is not included in the overall...
Instituting Increasing Block Rate Pricing as a Water Conservation Measure
The objective of this paper is to demonstrate the benefits of an increasing block rate pricing policy as a water conservation measure. By changing the pricing structure, demands will change...
Conflict Management Task Committee Approach
The Task Committee on Conflict Management (coordinated by the Social and Environmental Objectives and Impacts Committee, WRPMD), was established to develop guidelines for use by water...
Great Lakes Levels: Toward Systematic Decision Making
The International Joint Commission (IJC) has authority given by the governments of Canada and the United States to use existing works to regulate the lakes system according to agreed-to...
A Linear Dynamic Programming Model for the Optimal Allocation of Water in Groundwater Dependent Areas
The purpose of this paper is to describe an efficient computer-aided planning method using linear and dynamic programming together with a finite difference groundwater model to determine...
Daily Water Budget Model for Water Resources Management
A daily water budget model has been developed and tested for the Clinch and Powell watersheds located in SW Virginia and NE Tennessee. The model integrates available data and simulates...
