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...
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...
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...
Impact of Dynamic Loading on Bio-Phosphorus Removal
The ability of bench-scale activated sludge biological phosphorus removal systems to produce effluents with consistently low phosphorus concentrations was influenced by influent TOC/COD...
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...
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,...
Optimization Issues in the Design and Control of Large Space Structures
The optimization and identification issues which arise in the design and control of large flexible space structures are reviewed. The first paper examines the use of several different...
Institutional Constraints and Evaluation of Potential Management Strategies on the Colorado River System
Management of the Colorado River reservoir system is a complex problem influenced by a number of institutional constraints including interstate compact agreements, international treaties,...
Yield-ET Functions in Irrigation Systems Design
A linear-programming (LP) framework and associated computer routines were developed to evaluate economics of deficit irrigation in system design and to optimize the sizing and operation...
Examples of Sediment Distribution in the Italian Adriatic Coast. A Comparison Between the Shepard and the Nota Textural Classifications
Four sectors of the western Adriatic coast, each with a different feature, represent the test areas to evidence the differences between the two textural classifications of sediments by...
Hurricane Evacuation Studies, an Overview of Major Analyses
The purpose of this manuscript is to present the methods employed, the types of data generated and the interrelationships of the major analyses conducted for a hurricane evacuation study....
Estuary-Wide Mitigation Options for Port Development in Tampa Bay, Florida
The need for a regional strategy to address the environmental problems resulting from port development in Tampa Bay was recognized as important for the improvement and protection of the...
PVEM?A Model for Assessing Vessel Air Pollutants
The Port Vessel Emission Model (PVEM) is a computer program which calculates air pollutant emissions resulting from vessel activity in a port for various operations scenarios. These scenarios...
Quantifying Florida's Coastal Storm Wave Susceptibility
