Price Elasticity and Conservation Potential
Water conservation programs usually contain pricing incentives for users to limit water consumption. This analysis uses data from the Portland, Oregon water system as an example of both...
Seasonal Rates?The Pros and Cons: A Case Study
The Spring Valley Water Company, an investor owned water utility serving over 58,000 customers in Rockland County, New York, implemented a seasonal differential rate structure in 1980....
Urban Stormwater Runoff Control System?Village of Skokie, Illinois
Combined sewer systems in many communities lack the capacity to convey stormwater runoff from even small to moderate storm. This inadequate capacity, in turn, causes basement flooding...
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...
Storm Water Utility Experience in Bellevue, Washington
Surface water management is seen as a flood protector by most, a savior of the environment by some and a subversion of property rights by others. As recently as 20 years ago, there were...
Cross Section 90's?A Profile of User Fee Funded Stormwater Utility Practices in the U.S.
The task of securing adequate tax funding to support a stormwater drainage system regarding operating and capital needs is discussed. An innovative and practical solution was arrived at;...
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...
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...
Projecting Customers Using a GIS Land Use Forecasting Model
The Salt River project originally developed the Land Use Forecasting Model to understand the pattern of urbanization of agricultural and desert land in metropolitan Phoenix. The model...

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...
A Stochastic Cost Engineering System (SCENS) Applied to Estimating and Tendering for Bill of Quantities Contracts
In many countries, contracts based on bill of quantities are very common in construction industry. Although estimating and tendering are overwhelmed by uncertainties, the common practice...
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 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....
Computing with Objects: What Does Industry Hope to Gain from it
Although the need for an integration of engineering tasks has been stressed for a long time, the success that we see in this regard is very limited. We believe that there is justified...
