Use of Interactive Simulation Environments for the Development of Negotiation Tools
Interactive computer programs have been used successfully for many years to facilitate the planning and operation of water resources. Recently, advances in computer software have made...
Use of Interactive Simulation Environments for Evaluation of Water Supply Reliability
This paper investigates physical performance measures and their practical application to a regional water resource system for western Washington. Specific criteria for characterizing the...
Computer-Aided Support for Water Quality Modeling of the Russian River
A computer-aided support system for operation of the QUAL2E-UNCAS modeling packaged has been developed for modeling of the Russian River, California. The system has been created under...
A Decision Support System for Water Quality Modeling
A prototype Decision Support System (DSS) has been developed to evaluate the environmental and economic consequences of alternative farming practices. This system was developed to help...
Modified QUAL2E Modeling of a Stream Acutely Impacted by Photosynthesis and Respiration
The QUAL2E model was modified to account for time variable headwater conditions and the photosynthesis and respiration of attached aquatic plants. With these modifications, a stream that...
Hydrologic Investigation of the April, 1983 Flooding in New Orleans, Louisiana
During the rainstorm of April 6-7, 1983, a shell ramp was constructed over State Highway 406, closing the relatively shallow depression formed by the roadway passing over the levee which...
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'...
Computer Modeling Responsibilities for Municipalities
Municipal organizations are often faced with a complex set of water resource problems which can best be analyzed through the use of computer models. The development of such models can...
A Frequency Surface for Rainfall Intensity and Duration
A technique for developing rainfall intensity-duration-frequency surface is presented. With the aid of the Box-Cox power transformation raw data is transformed into a jointly near normally...
Prediction and Sensitivity of Recharges Due to Rainfall
This paper evaluates two models for predicting recharges due to rainfall: i) a simple mass balance model, and ii) a numerical model using the commercial software, UNSAT1. The models differ...
Highway Construction and a Trout Stream Relocation
In 1970, a ten-mile section of Traffic Route 15 in the northern portion of Lycoming County extending into Tioga County was under design as a two-lane limited access highway on four lane...
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...
A Demand Driven Decision Support System for Operation of Reservoirs
In this paper a stochastic optimization model, called Demand Driven Stochastic Dynamic Programming (DDSP) is developed and is compared with a Bayesian Stochastic Dynamic Programming (BSDP)....
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
