Water Data Bank of the Hashemite Kingdom of Jordan
The Hashemite Kingdom of Jordan and the United States of America have jointly undertaken an investigation of the ground-water resources of Northern Jordan. An initial step in the investigation...
State-of-the-Art Pipe Network Optimization
Within the next decade water distribution system optimization models should become everyday tools of practicing engineers. This paper examines existing models and discusses some of the...
Optimal Operation of a System of Lakes for Quality and Quantity
A methodology is presented combining simulation and optimization techniques for determining operation strategies for a system of lakes in the presence of quality and quantity constraints....
Real-Time Reservoir Operations by Quadratic Programming
A quadratic programming model is developed for real-time reservoir operations. It is assumed that convex penalty functions that relates the deviations of storage levels and downstream...
User-Friendly Reservoir Routing on Minicomputers
Two models for routing reservoir releases and computing reservoir elevations for the TVA reservoir system are described. The models are designed for use on a 16-bit minicomputer with a...
Conceptual Framework for Regression Modeling of Ground-Water Flow
The author examines the uses of ground-water flow models and which classes of use require treatment of stochastic components. He then compares traditional and stochastic procedures for...
Prior Information in the Geostatistical Approach
An overview of recent work on the geostatistical approach to the inverse problem of groundwater modeling is presented. A method which allows utilization of prior information about the...
Groundwater Modelling
The numerical simulation of groundwater flow and transport has evolved from a technical curiosity to an established method of hydrological analysis. In this brief review the progress that...
Numerical Modeling of Groundwater-Lake Systems
Groundwater inflows can have important effects on the chemistry and biology of a lake ecosystem. For example, studies of lakes in Northern Wisconsin documented localization of ferromanganese...
Utilization of Numerical Models in Groundwater
For many years numerical models have been used in groundwater hydrology. In a recent assessment of the availabilty and use of models, a number of problem areas were identified. Some of...
Risk Assessment for Groundwater Contamination: I
This paper constitutes Part I of a two-part article. Both parts focus on the risk assessment and management process in terms of the ever-present problem of groundwater contamination and...
Risk Assessment for Groundwater Contamination: II
This paper constitutes Part II of a two-part article. Both parts focus on the risk assessment and management process in terms of the ever-present problem of groundwater contamination and...
The Water Resources Models of the Instream Flow Group
The Instream Flow Group of the US Fish and Wildlife Service has five analytical systems designed to assist in the development of instream flow criteria for water resources projects. Models...
Digital Simulation of Flows in Hawaiian Soils
In attempting to numerically solve the nonlinear equation for flows in porous media, the Galerkin process, which bears a great similarity to direct methods of the calculus of variations,...
Use of a Two-Dimensional Flow Model to Quantify Aquatic Habitat
This paper describes the use of a numerical two-dimensional flow model to evaluate the impacts of potential hydropower retrofits on downstream flow distributions at Lock and Dam No. 8...
BAKWATR (3)--Computation of Gradually Varied Flow
The BAKWATR computer program computes profiles of gradually varied flow in open channels of irregular shape using a microcomputer. Channel cross sections are defined by a series of points...
Optimal Muskingum River Routing
The Muskingum method of river routing is well established and frequently used. An attempt is made to improve the method by optimal selection of the model parameters. The common linear...
Ground-Water Flow Model of Soda-Ash Waste Beds
A recent application by a steel manufacturing plant to obtain a permit for an industrial landfill located on top of abandoned soda-ash waste beds in the City of Syracuse, New York, resulted...
Groundwater Models in Choosing Water Treatment Methods
This paper presents an example of the use of groundwater models to identify the source of contamination and then design a treatment scheme. Included is a discussion of several different...
