Modeling Hydrologic Components of the Upper St. Johns River Project
Off-line stormwater management areas and riverine marsh conservation areas are the major components of the Upper St. Johns River Project, Florida. Dimensions and operations of these components...
Modeling Water Supply Benefits of a Shallow Lake in a River Reach
Minimum flow and level requirements based on ecological, water quality, recreation and other needs are established and used as limiting criteria in the development of a riverine lake as...
Water Quality Assessment and Management System in Regulatory Environments
State water quality regulatory agencies need to prioritize water bodies for program actions so that agency workload can be determined and resources allocated in order to achieve positive...
Mass Transport Modeling of Pearl Harbor
The U.S. Navy is planning to implement the use of organotin antifouling paints into the fleet. Such paints are already in use by commercial vessels and private pleasure crafts. As part...
Spreadsheet Applications in Water Quality Management
The state regulatory environment requires simple, quick, easy to use and maintain water quality analysis tools. Therefore, for the evaluation of toxic substances, a new approach towards...
Reservoir Safe Yield Evaluation Using Simulation
The safe yield available from surface water impoundments serving the City of Portsmouth, Virginia, was evaluated, and the sensitivity of the reservoir system to several factors was investigated....
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...
Conjunctive Use Study of Groundwater and Surface Water in Chino Basin, California
The purpose of this paper is to study the effects of artificial recharge on an already contaminated unconfined aquifer and propose optimal recharging and pumping schemes to prevent the...
Managing Microcomputer Applications
The authors have recently completed a study of microcomputer usage in Corps of Engineers planning activities. The study developed a training document for Corps managers, entitled 'Managing...
Living with a Macintosh in an IBM World
The Macintosh computer is widely praised for several characteristics: high resolution graphics, common program user interface, user friendliness including extensive use of a mouse, and...
Review of the Nation's Water Resources Infrastructure Needs

Sewer Rehabilitation?Metro Chicago
After a number of public hearings in the late 1960's and early 1970's which focused on sewer backup problems in the Sanitary District's separate...
Rehabilitation Strategies for Urban Drainage Systems?A European Perspective
Rehabilitation of urban drainage system is needed in many old European cities. This is in part due to the required structural upgrading of the existing sewerage system. But rehabilitation...
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...
