Engineering and Policymaking: The Platte River in Nebraska
Substantial conflict exists over proposed water projects in the Platte River Basin of Nebraska. A computer simulation model, representing the engineering and environmental dimensions of...

Modeling to Generate Alternatives: A Review
Modeling to generate alternatives (MGA) is a species of multiobjective programming in which some relevant objectives and perhaps some constraints are deliberately left unquantified. The...

Integrating Policy Factors in Stream-Aquifer Models
One of the main issues appearing today in the field of water resources is the management of complex hydrologic systems consisting of surface streams and aquifers. The management problem...

Prediction of Sediment Yield for Southern California Watersheds
The objective of this paper is to present a scientific method based on multiple linear regression analysis between the sediment yield per square mile and a number of physically realistic...

Hansen Dam Sediment Modeling Study Impact of Water Supply vs. Flood Control Operational Modes on Sediment Deposition in the Reservoir Area
The analysis of scour and deposition in Hansen Reservoir by modeling the interaction between the water-sediment mixture, sediment material forming the stream's boundary and...

Annual Sediment Loads of Illinois Streams
Incorporation of sedimentation surveys for 24 Illinois lakes was needed to provide somewhat long-term average sediment yields of Illinois streams. For each suspended sediment station a...

Storm Dynamics in the Lake Ontario Region
A program package, RAINPAK, was written to develop appropriate rainfall input, based on concepts of the physical processes behind the temporal and spatial distribution of storm rainfall...

Hydrodynamic Simulation of the Upper Potomac Estuary
Hydrodynamics of the upper extent of the Potomac Estuary between Indian Head and Morgantown, Md. , are simulated using a two-dimensional model. The model computes water-surface elevations...

Hydraulic Modeling for Ecological Research
Because of the problems and expenses of a continuous data collection program for large rivers, it was decided to develop an integrated hydrodynamic and biological model for the Illinois...

Computer Aided Drafting in the Water Resources Environment
The movement from traditional mechanical drafting to computer aided drafting in the small consulting business/research environment while necessary from the viewpoint of productivity and...

Interactive simulation of Water Resource Systems
This paper outlines some of the research currently underway at Cornell aimed at the design of an interactive simulation methododology. It describes the general approach to simulation modeling,...

Continuous Modelling of Downstream River Erosion Caused by 40 Years of Urbanization
The US EPA Stormwater Management Model (SWMM3) was installed on an IBM-PC compatible network. The adapted program, known as PCSWMM3, and incorporating a simple algorithm for modelling...

Converting a Mainframe Erosion Simulation Model to a Microcomputer Software
In this paper, techniques for mainframe to micro conversion are discussed. As a practical case, an erosion simulation model was used. The created software predicts distribution of erosion...

Advection Calculations Using Spline Schemes
The calculation of advective transport in one and two dimensions is done by the method of characteristics using spline interpolating polynomials at the forward time step. The method has...

A Computer Model for Oil Slick Transport in Rivers
A computer model for simulating oil slick transport in rivers is presented. In the model the effects of advection, spreading, evaporation, and dissolution on the transformation of an oil...

Orleans Parish Drainage Improvements
A case study of the development of an urban drainage master plan for Orleans Parish, Louisiana is presented. The Parish, which occupies an area of approximately 98,000 acres, lies entirely...

Water Resources Strategy - Chicago
Starting in the 1960's, a series of water quality and water resources studies focused on the problems of the Chicago metropolitan area. Some of these studies were among the...

Hale Cycle and Indian Drought and Flood Area Indices
The Indian Drought (DAI) and flood (FAI) area indices have been argued to be related to the hale cycle of sunspot number by H. N. Bhalme and D. A. Mooley. They studied the dependence between...

Development of Two- and Three-Dimensional Modeling Systems for Open Channel Flow and Sedimentation
Two- and three-dimensional numerical modeling systems have been developed to address questions of open channel flow and sedimentation for the Corps of Engineers. These systems are complete,...

Taming a Pipe Network Analysis Computer Program
The use of a conventional network analysis computer program as an effective evaluation tool for routine operation of an existing water distribution system has several practical limitations...
