Predicting Hydrologic Impacts of a Severe and Sustained Drought on the Colorado River Basin
We investigated the impacts of a severe and sustained drought (SSD) on the hydrology of the Colorado River Basin. The simulation was carried out using the Colorado River Network (CORN)...
Economic Impacts of Severe and Sustained Drought
A hydrologic-economic-legal impact model shows that a severe and sustained drought in the Colorado River Basin would cause acute economic damages to most instream water users, and to upper...
Missouri River Economic Impacts Model
The Missouri River basin recently (1987-1992) experienced a drought that affected project uses and environmental resources. This drought and the need to address changes that have occurred...
Stochastic Optimal Control for Determination of Freshwater Inflows to Estuaries
The objective of the research is to develop estuarine system management models based upon discrete-time stochastic optimal control. An analytical feedback control law is given. The control...
Multiobjective Models for Determining Freshwater Inflows to Bays and Estuaries
This paper presents four multiobjective models for the estuary management problem, including goal programming, the epsilon constraint method, the surrogate worth tradeoff method and the...
Differential Dynamic Programming for Estuarine Management
Differential dynamic programming (DDP) is applied to solve the estuarine management problem to determine the optimal amount of freshwater inflows into bays and estuaries in order to maximize...
Development and Application of Long Range Study (LRS) Model for Missouri River System
The Long Range Study (LRS) Model is a simulation model developed in the 1960's develop and test criteria for operation of the Missouri River mainstem reservoirs through an extended period...
Computer Simulation Model of the Integrated Local Water Supply Plan for the City of Wichita, Kansas
The City of Wichita, Kansas will require additional water supply sources to meet projected future water demands. A study of options identified a supply plan with integrated use of local...
Development of a Wetland/Riparian Resource Model for the Missouri River System
Wetlands and riparian areas are significant resources along the Missouri River, providing important fish and wildlife habitat. These resources required evaluation as part of the review...
Missouri River Least Tern and Piping Plover Model Development
As part of the update of the Missouri River Master Water Control Manual, the U.S. Army Corps of Engineers is evaluating the effects of numerous water management alternatives on endangered...
Development of Environmental Impacts Model for Missouri River System
The Corp of Engineers is reviewing the Missouri River Master Water Control Manual with the goal of determining the best plan for the Missouri River Basin. The Environmental Impacts Model...
Determining Optimal Parameter Dimensions for Water Distribution Network Models
Water distribution systems contain a large number of pipes whose roughness factors are unknown prior to model calibration. During the calibration process, pipe roughnesses for each link...
An Interactive Regional Regression Approach to Estimating Flood Quantiles
In Texas, a computer program has been developed which will estimate flood quantiles for an ungaged site based on data from gaging stations with similar watershed characteristics. The user...
WATSUP: A Simulation Model for Water Supply Cost and Reliability
WATSUP (Water Supply) is a computer model developed to provide a prototype modeling tool for planners to estimate the costs and reliability of urban water supply systems on a regional...
Parallel SDP for Multi-Reservoir Management
The use of stochastic dynamic programming (SDP) for solving water resources problems has been restricted to problems with low dimension due to the 'curse of dimensionality'. Algorithm...
Evaluating the Steady State Stochastic Dynamic Programming Model for the High Aswan Dam
The paper describes the results of a study to critically evaluate and test the Steady State Stochastic Dynamic Programming model (SSDP). Whenever a reservoir computer model is developed,...
Wet Detention Facility Pollutant Removal Modeling
This paper documents development of the WETPOND model, which simulates long-term pollutant removal by a wet detention facility. Pollutant removal is determined with an EPA procedure that...
An Integrated Approach to the Real-Time Control of Water Supply and Distribution Systems
In recent years, real-time automated operation and control schemes have been implemented for a number of water supply and distribution systems with varying degrees of success. This paper...
Reliability Analysis of a Multi-Reservoir Water Distribution System
A methodology for evaluating system reliability is developed to assist in the planning and management of a multi-reservoir water distribution system. The minimum cut-set approach is employed...
CAD for Small Hydro Projects
The quest to reduce design costs and improve design quality by raising productivity is familiar to every manager and designer. This article examines how CAD can play a role by examining...
