Two-Parameter Synthetic Unit Hydrograph for Microcomputer Application
A regression model was developed for estimating the unit hydrograph for ungaged watersheds. The model uses physical characteristics of the drainage basin to predict the parameters needed...

Interactive Computer Aided Graphic Water Well Pumping Test Evaluation Software
A microcomputer software package was developed which allows the user to interactively evaluate pumping tests using semilog and log-log graphic methods for time-drawdown, step-drawdown,...

Dual Drainage System Balancing Design Using Microcomputer Simulation
This paper describes the development and application of microcomputer software titled INTERHYD for design of a dual urban drainage system in Portland, Maine. The design problem consisted...

Advances in Selective Withdrawal
The authors present the results of recent selective withdrawal research in the form of a general mathematical description of this stratified flow phenomenon. A new description for boundary...

Solving the Two-Dimensional Diffusion Flow Model
A simplification of the two-dimensional (2-D) continuity and momentum equations is the diffusion equation. To investigate its capability, the numerical model using the diffusion approach...

A Micro-Computer Simulation Model Based on South African Hydrology
This paper presents the development of a micro-computer compatible hydrological simulation model wherein an attempt has been made to satisfy some of the modelling needs in South Africa....

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...

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
