The Strategic Development of a Sole Source Aquifer to Improve Water Quality While Minimizing Environmental Impact
A water supply project is currently underway which prevents future degradation of a sole source aquifer while providing a groundwater resource with limited usage restrictions. Salt water...
A Comparison of Short Term Forecast Methods for Municipal Water Use
Water utilities routinely develop long range demand forecasts for use in the normal planning activities. In recent years, many utilities have sought to develop more short-term demand forecasts...
Agricultural Water Conservation Technology Transfer
Efforts to implement computer programs which encourage water and energy conservation in the Columbia Basin, are described. Irrigators use the irrigation scheduling program to receive recommendations...
Flow Investigation for Landfill Leachate
A two-dimensional unsteady-state moisture flow model has been developed in order to describe the leachate flow process in a landfill. The unsteady variation of leachate mound head has...
The PULSEQUAL Model: Using Combinations of Simple Mathematical Equations to Evaluate Complex Storm Effects on Water Quality
Storm discharges (stormwater and combined sewer overflows) have transient and highly variable impacts on receiving waters. Simple water quality equations have been developed to accurately...
Combined Sewer Overflow Abatement Planning Based on SWMM EXTRAN Modeling
This paper discusses use of the Storm Water Management Model (SWMM), with the EXTRAN block as the hydraulic transport mechanism, as a tool for developing a facilities plan for abating...
Storage of Combined Sewer Overflow: How Effectibe is it Anyway?
The purpose of this paper is to illustrate the importance of modeling long term rainfall records to evaluate the effectiveness of combined sewer overflow storage. This paper will present...
Continuous Simulation Modeling for Sewer Systems
The peaking-factor method of sanitary sewer design was developed to simplify the calculations in determining design flow rates. This method of analysis is conservative to the point that...
Interactive Decision Support for Hydrologic, Hydraulic, & Instream Flow Criteria
Most often, impacts on natural resources from alternative river discharges are not quantified. The personal computer (PC) can provide access to useful techniques for analyzing multiobjective...
Alternatives Analysis Using Two-Dimensional Modeling for the Owensboro Bridge and Approaches
The Federal Highway Administration plans to design and construct a new bridge over the Ohio River near Owensboro Kentucky. A hydraulic model with two-dimensional capabilities was utilized....
Impact of Spatial and Temporal Data Limitations on the Modeling of Runoff Quantity and Quality
A small subbasin within an urbanized watershed (Reno, Nevada) was intensively monitored for runoff quantity and quality. The EPA Stormwater Management Model (SWMM) was applied to simulate...
Computer Analysis of Cable-Stayed & Suspension Bridges
The finite element structural analysis of long span bridges is an area of research that has been studied within the past thirty years since the development and emergence of the digital...
F. E. Everett Turnpike: An Application of MOSS
MOSS surface modeling software is being used successfully by Fay, Spofford & Thorndike, Inc., on a major project for the New Hampshire Department of Transportation to make improvements...
NOISE?A Comprehensive Software Library for Highway Noise Analysis
The Noise Software Library is a collection of highway noise analysis software tools that are arranged together under a powerful file management system which provides a transparent method...
The Application of AI in Highway CAD System
In a conventional CAD System, the process for solving a certain particular engineering problem is fixed stationary in the program. As a result, the program is often modified to fit different...
The 3D Approach to Design
Designing directly in three dimensions, including integrated analysis and information flow, is a powerful way to enhance civil engineering capabilities. Yet, relatively few have taken...
Designing in Three Dimensions for Manufacturing Facilities
Du Pont Engineering is using Three-Dimensional Design for the design of our manufacturing facilities. Our 3D design system was used on several projects in 1992, and full implementation...
Object Oriented Modeling of Structural Systems
Computational engineering in structural design is no longer restricted to numerical approaches. Increasingly, also non-numerical, in particular, cognitive problems can be implemented into...
Object-Oriented Modelling for Concrete Structures
The use of computers for the design process has reached wide acceptance. The use is developed in several fields such as CAD, CAM or programs for design of structural elements. Recent work...
Object-Oriented Data Exchange for the Integration of Design Processes in Structural Engineering
The computer integration of tasks, activities, tools, user and data exchange interfaces, management of knowledge etc. requires a new approach by object-oriented modeling in civil engineering....
