Suspended Sediment Transport from Nonpoint Sources
Precipitation, runoff, and suspended sediment concentration data were collected in a predominantly agricultural watershed in southwestern Illinois from January 1982 through October 1984....

Overview of EPRI'S Solid Waste Environmental Studies
The Electric Power Research Institute (EPRI) initiated a comprehensive research project in 1983 with the long-term goal of improving and validating methods for predicting the fate of chemicals...

Browns Ferry Nuclear Plant: Twenty Years Experience with Changing Thermal Criteria
This paper and its companion papers focus on one aspect of the environmental impact of Browns Ferry - the discharge of heated water. The paper provides a description of the site and the...

Browns Ferry Nuclear Plant Thermal Compliance Monitoring Network: Utilization of Data
An automated water temperature monitoring network was designed to measure ambient and downstream heated river temperatures at Browns Ferry Nuclear Plant (BFN) in Wheeler Reservoir. The...

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...

Simulation of Far-Field Thermal Effects from Browns Ferry Nuclear Plant
A computer model was used to evaluate the far-field effects of revised thermal discharge limitations at the Tennessee Valley Authority's Browns Ferry Nuclear Plant (BFN)....

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...

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...

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....

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...

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...

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...

Turbine Efficiency Loss Associated with Draft Tube Aeration
Draft tube aeration is one method for improving the dissolved oxygen content of hydroelectric discharge. A simple analytical procedure is presented for estimating the loss in turbine efficiency...

Lake Water Level and Sediment Management?Case Studies in Illinois
Estimation of the sedimentation in the lake is based on the soil erosion rates in the watershed, the sediment transport in the stream system, and lake trap efficiency. Erosion rates are...

Exfiltration Trench Design as Part of a Stormwater Management Plan
The paper discusses a program structured to assist the design consultant or the agency reviewer by means of a menu driven format. A flood routing microcomputer program developed by the...

Overtopping of Small Dams?An Alternative for Dam Safety
A research effort was initiated in 1983 by the Bureau of Reclamation to gain insight in the development of cost-effective modifications to small embankment dams which would enable them...

Embankment Overtopping
Embankment overtopping and dam safety are major concerns of civil engineering and the general public. Very little is known about overtopping events and much less has been published or...
