Event Tree Analysis of Lock Closure Risks
(American Society of Civil Engineers, 1997)The use of event trees and subjective probabilities in risk analysis is illustrated via a case study: the estimation of the probability of closure of Poe Lock on St. Marys River (Sault Ste. Marie, Mich.) because of vessel ... -
Genetic Algorithms for Least-Cost Design of Water Distribution Networks
(American Society of Civil Engineers, 1997)The paper describes the development of a computer model GANET that involves the application of an area of evolutionary computing, better known as genetic algorithms, to the problem of least-cost design of water distribution ... -
Multiobjective Analysis of Service-Water-Transmission Systems
(American Society of Civil Engineers, 1997)A multiobjective analysis technique is presented to determine the optimum operation of pumps and reservoirs in service-water-transmission systems. Three major objectives were identified as (1) economics in terms of energy ... -
California's 1995 Water Bank Program: Purchasing Water Supply Options
(American Society of Civil Engineers, 1997)In anticipation of a second consecutive critically dry year, the California Department of Water Resources (DWR) organized the 1995 Drought Water Bank Program. For the first time, DWR purchased water supply options from ... -
Optimal Operation of Regional System with Diverse Water Quality Sources
(American Society of Civil Engineers, 1997)A management model for optimal operation and control of a regional water system is developed and evaluated. The system consists of numerous water sources with various qualities and consumers with differing flow rates and ... -
Water Supply Planning Simulation Model Using Mixed-Integer Linear Programming “Engine”
(American Society of Civil Engineers, 1997)This paper presents a simulation model to be used for water supply planning by a metropolitan water utility. Water supply operations for a single, monthly time step are formulated as a mixed integer linear program (or more ... -
Estimating Flood Frequency and Average Annual Damage
(American Society of Civil Engineers, 1997)In the National Research Council (NRC) report, “Flood Risk Management and the American River Basin—An Evaluation,” the use of expected probability (accounting for sampling uncertainty) in estimating flood frequencies and ... -
Expected Probability and Annual Damage Estimators
(American Society of Civil Engineers, 1997)Controversy continues over the relative merits of traditional frequency estimators and the “expected probability” estimator of flood risk that incorporates an adjustment for parameter uncertainty. Both have solid theoretical ... -
Optimal Ground-Water Pollution Plume Containment with Fixed Charges
(American Society of Civil Engineers, 1997)Six ground-water management models were developed and compared to identify the best management alternative for the containment of a ground-water pollution plume in a hypothetical aquifer that is used for freshwater supply. ... -
Finding Robust Solutions to Water Resources Problems
(American Society of Civil Engineers, 1997)Water resources planners and managers are continually faced with decisions to be made under uncertainty. In planning problems such as water supply, flood control, and ground-water remediation, the trade-offs among expected ... -
Autoregressive Decision Rule in Aggregated Reservoir Operation
(American Society of Civil Engineers, 1996)Lag-1 correlation for inflow between consecutive periods is considered into reservoir model in many publications. This consideration greatly improves the reservoir models to incorporate the uncertainty of inflow. However, ... -
Network Flow Programming Model for Multireservoir Sizing
(American Society of Civil Engineers, 1997)The paper describes a network flow programming (NFP) model for sizing of reservoirs in a multiple reservoir design problem. It is a multiperiod model, where all single period networks, representing reservoirs, rivers, ... -
Optimal Stochastic Multicrop Seasonal and Intraseasonal Irrigation Control
(American Society of Civil Engineers, 1997)Optimal seasonal multicrop irrigation water allocation and optimal stochastic intraseasonal (daily) irrigation scheduling are carried out using a two-stage decomposition approach based on a stochastic dynamic programming ... -
Dynamic Optimal Ground-Water Reclamation with Treatment Capital Costs
(American Society of Civil Engineers, 1997)A dynamic optimal control algorithm for ground-water remediation was extended to incorporate treatment facility capital costs, as a function of the peak operating rate. Our approach to including the capital costs of treatment ... -

Multicriterion Design of Long-Term Water Supply in Southern France
(American Society of Civil Engineers, 1996)A multicriterion decision-making (MCDM) methodology is developed to design a long-term water supply system involving multiple actors. A 1989 regional development plan for augmenting water resources in the Adour-Garonne ... -
Mixed Optimization Technique for Large-Scale Water-Resource Systems
(American Society of Civil Engineers, 1996)Dealing with significantly large design problems for water-resource systems a mixed optimization procedure based on network linear programming and the subgradient method will be described. Using a linear problem formulation, ... -
Optimal Estimation of Storage-Release Alternatives for Storm-Water Detention Systems
(American Society of Civil Engineers, 1996)A heuristic optimization methodology is developed for obtaining the optimal allocation of storage capacity and release rate for the design of storm-water detention facilities. The nonlinear optimization procedure is ...
