Hydrologic Work Group System Using Distributed Task Processing
The notion behind work group systems is that a collection of co-workers, numbering from a few to a few tens of people, is the logical unit around which to build a centralized microcomputer...
The National Water Well Association's Ground Water Software Centre
The National Water Well Association (NWWA) offers a new service to the members of the ground water industry. NWWA's Ground Water Software Centre markets computer programs...
Microcomputer Application in Predicting Upland Erosion
An erosion-deposition model, originally developed for a mainframe computer, was adapted for an Apple IIe. With minimal adjustment it can also be used on other personal microcomputers....
The SRI Technique for Flood Frequency Analysis
This paper presents a technique for flood flow frequency analysis called the Storm Response Index (SRI), and a case study using the technique. The SRI method is based on the development...
Evaluating Water Policy Options by Simulation
Computer simulation models are used to predict the effects of three sample water policy decisions on selected conjunctive water use/sustained groundwater yield strategies for the Arkansas...
Indoor Air Quality Simulations with the Mass Balance Model
Recent studies relate energy conservation measures, specifically to reduction of the air exchange rate of residences, with potential adverse health effects due to human exposure to increased...
Groundwater Studies for Land Treatment Facility
A wastewater treatment facility currently under construction in Falmouth, Massachusetts, features a dual disposal method for land application of effluent. As the effluent disposal site...
Computer Control of Lift Station Operations
A unique computerized control system to supervise the operation of several lift stations has been designed by Boyle Engineering Corporation (Boyle) and constructed by the City of Orlando,...
Simplified Methods to Predict the Fate of Metals in Rives
Heavy metal contamination of rivers is of increasing concern to society. To help predict the fate of metals in rivers, researchers have developed computer models to simulate speciation...
NCASI Enhancements of the QUAL-II Model
The mathematical water quality model QUAL-II has been modified to reflect advances in the understanding of algal, nutrient, and light interactions. Code changes were also made to incorporate...
Computer Simulation of Lime-Soda Softening of Cooling Waters
A computer model is developed to simulate the process of lime-soda softening of cooling waters. Results from the model are compared with those from a laboratory experimental study using...
Wetland Protection Regulations: A Technical Perspective
This paper summarizes the technical basis for the application of wetland protection regulatory schemes upon a number of typical environmental engineering and related projects. A number...
Saving Time and Money with Archaeology
In the past 20 years, archaeology has become a necessary part of many engineering projects. However, this aspect of a project is often regarded as an obstacle in terms of costs and time....
A Computer Aided Approach to Missing Time-Series Data Replacement
The objective of this research is to design, construct, and demonstrate a computer utility which will interactively aid the time series researcher in choosing an appropriate missing data...
Environmental Infrastructure: Does Civil Engineering Education Meet the Challenge?
The author explores some avenues for re-direction of the civil engineering education process to become more responsive to the needs of infrastructure re-development in the areas of water...
A Stepwise Approach to Environmental Systems Maintenance Management
This paper provides a systematic approach to establishing a maintenance management program for environmental infrastructure. It begins by discussing the definition of program objectives,...
Microcomputer Methods for Toxicants in Ground Waters and Rivers
This paper describes a program written for the IBM personal computers to assess the fate of toxicants in ground waters and in rivers. The algorithms in the program were selected from a...
Theoretical and Experimental Evaluation of Single-Activated Sludge
The objective of this paper is to discuss the results of operating a laboratory bench scale compartmentalized activated sludge unit operated at a hydraulic detention time ( theta ) of...
Health Effects Evaluation?Ocean Disposal of Sludge
Court rulings have recently allowed the ocean disposal of municipal wastewater sludge in certain cases. This paper describes a methodology which was developed to determine acceptable loadings...
Three-Dimensional Simulation of Flow and Sewage Effluent Migration in the Strait of Juan de Fuca, Washington
The purpose of this study was to evaluate effects of a proposed sewage effluent discharge located in the Strait of Juan de Fuca just outside of Sequim Bay, Washignton. The three-dimensional,...
