Water Surface Profiles in Compound Channels
The paper explores the use of the proposed compound channel Froude number in problems of water surface profile computation. It can be used not only to determine critical depth and to identify...

Reactive Transport of Suspended Particles
Monte Carlo simulation of the total probability density function for each constituent easily handles non-linear reactions and has a cost that increases only linearly with the number of...

Computer Simulation of Coagulation
Coagulation, the process of collision and coalescence of particles, modifies the size distribution of the suspended mass, continuously creating larger particles which may settle out of...

A Numerical Model of Water Movement Through Clay Liners
Regulations controlling landfill design typically specify design details such as a minimum liner thickness, maximum permeability of required gradation curves for the clay liner material....

Ground Water Management Using Computers
Both a mainframe and personal computers are used by the Water Use Division of the South Florida Water Management District in the consumptive water use permitting process. Numerical and...

Microcomputer-Based Index Testing of Hydroturbines
A computer-assisted system for performing index test on hydroturbines is described. This system allows for more rapid and accurate index testing of hydroturbines than has previously been...

Microcomputer Control for a Small Hydroelectric Peaking Plant
Peaking plants pose a special problem for control. The new facilities are generally a very small part of a large system. Determination of the parameters necessary to run the plant to best...

Statewide Hydrologic Data Base and Analysis System
The Wyoming Water Research Center (WWRC) at the University of Wyoming has developed, in cooperation with the Wyoming State Engineer's Office, a statewide Water Resources Data System (WRDS)...

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...

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,...

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...

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...

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...

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...
