Evaluating Sensitivity of Hydraulic Control Optimization Models
Sensitivity of hydraulic control optimization models to variation in gradient constraints is examined. Monte Carlo simulation is used in conjunction with repeated optimization runs to...
Joint Probability Distribution of Rainfall Intensity and Duration
Intensity-duration-frequency (IDF) curves are widely used for peak discharge estimation in designing hydraulic structures. Accurate interpolated and extrapolated intensity values are difficult...
Aquifer Remediation Design: Nonlinear Programming and Genetic Algorithms
Nonlinear programming and genetic algorithm solutions of a pump-and-treat aquifer remediation design model are presented and discussed. These models find the minimum cost design of the...
Integration of Reliability, Uncertainty and Optimization in Hydraulics Systems: Structural Reliability
The focus of this paper is to provide an overview of analysis and optimal design of systems in which the system reliability is dependent upon the structure of the system (such as the layout...
Designing Optimal Reliable Multiquality Water Supply Systems
A methodology which integrates optimal design and reliability of a multiquality water supply system is presented and demonstrated. The system constructed is able to sustain prescribed...
A Decision Support System for Reassessing the Operation of the Chungju Reservoir System
The Chungju Reservoir is a component of the Han River System in Korea. Chungju Reservoir consists of a main reservoir and a downstream smaller reservoir that serves as an after bay. It...
A Decision Support System for Multi-Purpose Reservoir Operations
A generalized decision support system (DSS) is presented for developing optimal operation policies for multi-purpose reservoirs. The model is designed for single reservoirs, although is...
A Physically Based Conceptual Model for Simulating Contaminant Levels in Subsurface Water
A conceptual physical model is developed to simulate solute transport and mixing in the vadose (unsaturated) and groundwater zones. The conceptual model couples lumped-parameters models...
Climate Change Impacts on Boston's Water Supply
The analysis of the climate sensitivity of the water supply system of the Boston area indicates that the water supply has the potential to be dramatically altered by global warming. The...
Wetland Loss Rates and Agricultural Drainage
The current paper uses National Resources Inventory data to document the relation between private on-farm agricultural drainage investment activity and wetlands loss. The paper presents...
Peak Runoff Prediction for Small Rural Watersheds
A regression model for peak runoff prediction from small rural watersheds was developed using the rainfall/runoff data collected from 43 watersheds in the front range of the State of Colorado....
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...
Plate and Frame Membrane Air Stripping
This paper examines utilization of a plate and frame membrane air stripping system for the removal of volatile organic chemicals (VOCs) and radon from a water supply. Previous work explored...
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...
Low-Flow Frequency Analysis with Censored Data
Log-linear regression models are often fit to low-flow quantile estimates from gauged sites to obtain a relationship for estimating low-flow quantiles at ungauged sites. In some regions...
Analysis of Missouri River System Operations Alternatives
The Corps of Engineers is conducting a study of alternative water control plans for the exiting Missouri River Mainstem System. Data on the effects of the alternatives on the various project...
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,...
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...
