LANDSAT and Micro-GIS for Watershed Modeling
A microcomputer-based Geographic Information System (GIS) incorporating LANDSAT or other remotely sensed digital data greatly reduces the cost of watershed modeling. The computation of...
Numerical Models for Two-Dimensional Surface Runoff
Numerical models for surface runoff in watersheds having two-dimensional or horizontally varying topography are presented. Two finite element methodologies, a standard Galerkin and a streamline...
Input/Output Schemes for Microconverted Engineering Application Programs
When converting mainframe programs for microcomputer use, different input/output schemes are implemented depending on the type and volume of program data and ultimate use of the program....
Flow and Mixing Calculations for a Two-Dimensional Reservoir Water Quality Model
A two-dimensional reservoir water quality box model has been developed and applied to several Tennessee Valley Authority reservoirs including a mainstem reservoir that is fully mixed vertically,...
Thermal Plume Model for Demonstrating Compliance
A numerical model that simulates the discharge of heated water from a multiport line diffuser to a thermally stratified, flowing environment was developed. The model solves the conservation...
Numerical Waterbody Dynamics and Small Computers
The numerical hydrodynamics of free surface flows as applied to waterbodies presents a number of challenges, including choice of the spatial differencing schemes including representation...
Report of the Task Committee on Test Cases for Verification of 2-D Depth-Averaged Hydrodynamic Models
The Computational Hydraulics Committee has established a Task Committee to identify test cases which can form a uniform, objective basis for model verification. The scope is limited to...
Sedimentation of Waste Particles in Coastal Waters
Environmental effects associated with various ocean disposal practices are determined to a large extent by the fate of waste particles. The importance of coagulation on particle deposition...
Brownian Coagulation in the Initial Mixing Region of a Buoyant Plume
The paper discusses reactive systems that share the following common phenomenon: their reaction is either controlled by both kinetics and diffusion, or fully by diffusion. It reports on...
Particle Sizes in Flocculation and Sedimentation: Models and Experiments
D. F. Lawler et al. developed a model for flocculation, sedimentation, and filtration and predicted the effects of particle size distribution and concentration of the influent in water...
Present Status of Research in Debris Flow Modeling
A viable rheological model should consist of both a time-independent part and a time-dependent part. A generalized viscoplastic fluid model that has both parts as well as two major rheological...
Using Microcomputers for Groundwater Flow Analysis
Micro-computers offer an effective and efficient method for rapid and comprehensive analyses of groundwater flow. There are now numerous codes which have been developed specifically for...
Monitoring Well Inventory Using Database Development Software
The South Florida Water Management District (SFWMD) is assisting the Florida Department of Environmental Regulation (FDER) in the establishment of a central repository for statewide hydrologic...
Modeling Aquifer Sensitivity and Leachate Controls
This paper investigates the transport of waste leachate from a leaky containment facility using the computer model of Two-Dimensional Solute Transport and Dispersion in Ground Water developed...
Computer Aided Design of Ground-Water Monitoring Programs
Preliminary evaluation of flow patterns and plume migration by computer simulation aids in determining the spacing of monitoring devices perpendicular to the flow direction, the location...
Economics of Hydrothermal Power Development
The overall performance of a hydrothermal power plant with pumped storage is more cost effective than its competitive counterparts such as oil and gas turbine-generators. The operation...
Seasonal Hydrothermal Operating Plans
An interactive computer model is presented which provides graphical displays of alternative generation patterns for an integrated hydroelectric and thermal system. The method for analyzing...
Portland's New Water Pumping and Hydropower Station
The City of Portland, Oregon, recently placed into service a 100 mgd pumping station as a major milestone in developing a backup and emergency groundwater supply. The facility is also...
