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...
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...
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...
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...
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....
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...
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...
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...
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...
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...
