The Effects of Long Term Withdrawals on the Mid and Lower Hawthorne Aquifers, Cape Coral, Florida
The paper reports on a study to assess the water resource availability of two artesian aquifers (the mid-Hawthorn and lower Hawthorn) in Cape Coral, Florida. The impacts of future withdrawal...

A General Microcomputer Approach for Evaluating Ground-Water Responses
A general impulse response function for calculating responses for stream-aquifer interaction, pumping in leaky and nonleaky artesian aquifers, and two dimensional dispersion is presented....

Entrainment of Interstitial Water by Overland Flow
The paper reports on a study to investigate the entrainment of interstitial soil water by overland flow. A diffusion model was developed to describe the subsurface concentration and the...

A Ground Water Flow Model for Protection of the Northwest Well Field, Dade County, Florida
A new study was initiated to determine the appropriate cone of depression for the Northwest Well Field and to develop land use restrictions within that area. A finite-difference ground...

Computer Modeling of Groundwater Flow
In attempting to numerically solve the nonlinear equation for flows in porous media, the Galerkin process, which bears a great similarity to direct methods of the calculus of variations,...

Applications of a Diffuser Performance Model at Browns Ferry Nuclear Plant
An unsteady flow model and a diffuser performance formulation were combined to more accurately determine plant-induced temperature effects. This model has been applied to several aspects...

Eight Open Channel Flow Programs for the Apple IIe Microcomputer
The purpose of this paper is to present eight programs in hydraulics and hydrology suitable for running on the Apple IIe and Apple IIc microcomputers. The programs are: Flood 1, Flood...

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...

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...
