Expert Systems for Drought Management: A Case Study
This paper describes the development and application of a computer model used by the Seattle Water Department (SWD) for operations during drought. This model provides guidance for initiating...

An Operations Advisor for Regional Water Management
The application of artificial intelligence techniques was evaluated for implementation for water control structure operations at the South Florida Water Management District. After an analysis...

Design of the Oasis Advisory System
Once the decision was made to develop an advisory system for the operation of water control structures within the South Florida Water Management District, a schedule of activities leading...

Assessing WQ Impacts Using a Hydraulic Model
Engineering projects may cause water quality impacts in estuarine systems. It is important to assess those impacts during the planning phase of the project so that mitigation measures...

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...

Sanitary Sewer Model with Database Management
While numerous water supply and stormwater system models existed, the few sanitary sewer models that were readily available were too simplistic for engineering design and master planning...

Sanitary Sewer System Modeling for Operation and Planning
Development of a Steady State Sanitary Sewer Simulation (S⁵) computer model helped Newport News, Virginia, enact an efficient sanitary sewer management...

Computer-Aided Wastewater Master Planning
Computerized wastewater collection system modeling is a tool now used by city planners and engineers to efficiently and accurately analyze present and future conditions. Once a model has...

An Intelligent Design Support System for Computer-Aided Site Development
This research proposes an intelligent design support system (DSS) integrated with a CAD environment for building site planning and development. The DSS is used for providing a good initial...

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...

Revising a Reservoir Rule Curve for Multiple Uses
The Jackson Hydroelectric Project generates power, supplies municipal water, provides flood control, maintains anadromous fishery minimum instream flows and studies various reservoir rule...

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....

Stochastic Model for the Management of a Stream-Aquifer System
The management of a system of groundwater and surface water requires that the hydraulic connection of the two sources be investigated. The inherent uncertainties that exist in the data,...

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...

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,...

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,...

Hydrologic and Hydraulic Calibration?A Case Study (a)
The Addison Creek watershed is in Cook and DuPage Counties just west of Chicago, Illinois. Because the watershed has a history of major flooding, eight major stormwater and flood control...
