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...
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...
Analyzing Combined Sewer Overflow Events
The Illinois Environmental Protection Agency/Illinois Pollution Control Board (ILEPA/IPCB) direct that combined sewer system overflows (CSO) be given sufficient treatment including 'first...
Small Canal Discharge Measurement by Thermal Dilution
Thermal dilution is a variation of the indicator dilution flow measurement technique, utilizing heat as the indicator. The measurement is accomplished by performing a heat balance within...
Assessment of Water-Shortage Risks Under Various Use Options for Cedar Bluff Reservoir
Cedar Bluff Reservoir is located on the Smoky Hill River near Arnold, Kansas, with a drainage area of 5,530 mi**2. The reservoir was originally built for flood control, irrigation and...
Coagulation in Natural Waters
The hydrodynamics and chemistry of particle-particle interactions can control the transport of particles and of particle-reactive pollutants. In lakes, particle deposition is accomplished...
Physical and Chemical Behavior of Chrysotile Asbestos Particles in Natural Waters
The paper reports on research to develop a better understanding of the chemical behavior and the influence of surface chemistry on the physical behavior of chrysotile asbestos and other...
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...
Ground-Water Drainage to Surface Mines Refined
Changes in seepage flux and hydraulic head (ground-water level) resulting from ground-water drainage into the first and subsequent cuts of a surface coal mine can be estimated by a technique...
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...
Experimental Study of the Cross-Flow-Turbine
The performance of the Cross-Flow or Banki Turbine (C-F-T) was studied experimentally by varying the number of blades, the runner diameter, and the nozzle entry arc under flow/head variations....
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)...
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...
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...
