Seasonal Water Quality Management Given Sparse Data
An approach for designing robust seasonal water quality management programs for river basins with sparse or short flow records is presented. This approach uses Markov chain modelling and...
Groundwater Contaminant Transport at a Hazardous Waste Disposal Site, Pullman, Washington
Groundwater contamination at a hazardous waste site near Pullman, Washington is simulated by a numerical model. The aquifer at the site is classified as an unconfined valley aquifer. Solute...
The West Point Story?Chapter 1: Overview and Planning
The West Point wastewater treatment plant is the Seattle metropolitan area's largest wastewater treatment plant, and it is being upgraded to provide secondary treatment. The planning,...
The West Point Story?Chapter 2: Project Management Approach
In 1985, serving as the program lead, Metro contracted with Lewis Zimmerman Associates to conduct a formal facility planning effort for the West Point wastewater treatment plant. It was...
The West Point Story?Chapter 4: Design
Metro's approach to design was one of integrated environmental and plant design. The project team, with guidance from the community and the city's parks department, established goals before...
The West Point Story?Chapter 5: Construction
As design of the West Point plant neared completion, the municipality of Seattle addressed construction of the facilities. The challenge was to build a complex wastewater treatment plant...
Low Flush Plumbing Fixtures and Wastewater Systems
The significance of low flush plumbing fixtures on the wastewater collection and treatment system serving a small community has been determined. Among the concerns studied were: functional...
Use of a Statistical Model to Forecast Future Wastewater Flows
Future wastewater flows are generally predicted based upon an assumed rate of population and industry growth within a treatment facility's area of influence. In a community with limited...
Bellingham Frozen Foods Spray Irrigation System Operations
Bellingham Frozen Foods is a major vegetable processor located in northwestern Washington state. During the mid-1980's, the city of Bellingham began to upgrade the treatment of wastewater....
Urban Runoff Considerations in the Design of Wastewater Management Programs for Coastal Areas
The continuing increase in the population of the nation's coastal areas is placing additional stress on coastal aquatic systems faster than it can be reduced through improved wastewater...
Storage/Treatment Isoquants for CSO Control Planning
A quantitative procedure which identifies the technically efficient combinations of storage volume and treatment rate necessary to achieve various levels of combined sewer overflows (CSO)...
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...
Assessment and Mitigation for Endangered Vernal Pool Invertebrates
The USFWS is considering declaring five species of vernal pool invertebrates endangered. Among these are the Vernal Pool Fairy Shrimp (Branchinecta lynchi), the California Linderiella...

A Structural Analysis System
In this paper, the importance of the structural analysis in accordance with the construction progress was emphasized to accurately predict the structural behavior of prestressed concrete...
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...
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 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...
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...
