Prescriptive Model for Missouri River Reservoir-operation Analysis
The six main-stem reservoirs of the Missouri river system are operated by the Corps of Engineers for flood control, navigation, irrigation, power, water supply, water quality control,...

Winter Nutrient Losses to Groundwater Associated with Various Tillage Manure Systems
Excessive nutrient leaching to groundwater in agricultural watersheds has initiated research to develop control systems. Loading of nutrients are enhanced during the non-growing season...

Loading of Nutrients to Groundwater From High Source Areas During the Winter Period
Nutrient loading to surface, subsurface and groundwater in agricultural areas is the focus of control programs throughout the United States. In certain cases, high source areas can be...

Fingerprint Identification of Groundwater Petroleum Contamination Using Synchronous Scanning Fluorescence
Synchronous scanning fluorescence spectroscopy, SSF, is a simple, cost effective method for the fingerprint analysis of many petroleum contaminates in groundwater and soil samples. The...

Modeling of a Large-Scale Water Distribution System
Metropolitan Water District of Southern California (MWD) imports water from the California State Water Project and the Colorado River, providing for supplemental water demands for six...

Energy Efficient Pump Station Operation with a Pump Switching Constraint
Pump operation scheduling has become a significant practical and research concern as utilities increase their computer usage. This paper presents an integer programming algorithm which...

Case Studies of Utilizing a Flexible Automated Supply in Developing Countries
The need is seldom questioned for a water supply that is available when the crop needs it - frequency; at a rate that can be satisfactorily used; and for a duration that provides just...

The Total System Solution
Most pipeline reconstruction programs carried out to date have been crisis driven or reactive instead of system wide approaches to problem solving. Two tools have been devised to change...

Reservoir System Reliability Constrained by Natural Salt Pollution
A generalized reservoir system simulation model, which incorporates salinity considerations, has been developed and is presently being applied to a system of 12 reservoirs in the Brazos...

Development of a Phase I Prescriptive Reservoir Model
The U.S. Army Corps of Engineers Hydrologic Engineering Center (HEC) has recently developed a Phase I generalized prescriptive reservoir model referred to as HEC-PRM. The purpose of the...

Reliability of Operating Rules with or without Uncertain Forecasts
In this study the reliability indices are calculated for operating policies generated by three Stochastic Dynamic optimization models: a classical Stochastic Dynamic Programming (SDP);...

The Challenge of Kissimmee River Restoration
Between 1962 and 1971, the Kissimmee River in central Florida was channelized by the Corps of Engineers as part of a flood control project. Channelization has resulted in degradation of...

Usefulness of Low-Cost Watershed Monitoring: A Case Study
A one-year monitoring study was conducted for Harford County, Maryland to identify water quality problems and sources in the 98 mi² Bush River watershed....

Water Main Rehabilitation Needs for the 1990's
Distribution systems represent the major portion of water utilities capital assets. There are growing concerns about water quality deterioration within distribution systems, and hydraulic...

A Review of Current UK Techniques for Rehabilitating Water Mains
This paper describes the main techniques used in the UK Water Industry to rehabilitate water mains, highlighting their advantages and disadvantages....

Cost of Rehabilitation of Water Distribution Systems
The Chester Water Authority was established in 1868 and supplies water to residential and industrial customers in three counties in Southeastern Pennsylvania, and in addition, wholesales...

Water Main Rehabilitation Using Silicote Lining
In an attempt to find a cost effective rehabilitation alternative for over 320 miles of unlined distribution water main, the Louisville Water Company has evaluated a new rehabilitation...

Use of Contaminant Mobility and Transport Parameters to Determine Water Testing Protocol
By 1994, EPA plans to regulate 83 contaminants in public water supplies. For rural communities and individuals who are not classified as public systems, the cost to monitor all 83 contaminants...

Expert System for Operating A Treated Water Supply System
This paper presents a systematic approach to the development of an expert system to operate a treated water supply system for meeting daily water requirements. A treated water supply system...
