Extended Experience with a Short-Term Hydropower Scheduling Model in New England
The New England Power Exchange (NEPEX) is responsible for the central dispatch of power throughout New England. To assure the maximum benefits of power pooling, the electric facilities...

Planning and Operation of a Multi-Reservoir Water Distribution System
A water supply distribution system planning model (DSPM) is developed using a directed graph algorithm as its pre- and post-processors and a linear programming (LP) procedure as an `intelligent'...

Water Availability and Water Demand Study for the Citanduy River Basin, West and Central Java, Indonesia
This paper will discuss the water availability and water demands in the Citanduy River Basin located in West and Central Java, Indonesia. A program of development of water and other natural...

Alternative Methods of Drainage Management in San Joaquin Valley, California
The subsurface drainage and drainage-related problems in the San Joaquin Valley cost millions of dollars to the State and local economy every year. A number of actions have been proposed...

Feasibility of Water Supply for City of Houston Subsidence Zones Five and Six
The purpose of this paper is to evaluate the feasibility of providing surface water to the Harris Galveston Coastal Subsidence District (HGCSD) Zones Five and Six (located in North Houston...

Information Theory and Multi-Objective Evaluation
The evaluation of alternatives with scarce knowledge is a common decision-making situation. This situation contrasts with decision-making in the presence of abundant knowledge, which is...

Dry Weather Field Screening as an Indicator for Urban Drainage System Rehabilitation
In November 1990, EPA published final rules governing National Pollution Discharge Elimination System (NPDES) Permit Application Regulations for stormwater discharges. The rules affect...

Design and Maintenance of Rural Water Supply Systems for Improved Performance
During the period 1980-1990 the United Nations sponsored a comprehensive effort to bring potable water supplies throughout the world. For many urban and rural areas in developing countries...

Coupled Water-Wastewater Management Issues
The concept of coupled alternatives is an emerging engineering issue in master planning for water resources management. Coupled alternatives involve the concurrent evaluation of water...

On-Line Optimal Control of Urban Water Supply
There has been some interest in optimizing water delivery systems, but as yet, no one has developed an on-line optimal control algorithm. This paper explains the approach Memphis State...

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...
