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...
Particle Sizes in Flocculation and Sedimentation: Models and Experiments
D. F. Lawler et al. developed a model for flocculation, sedimentation, and filtration and predicted the effects of particle size distribution and concentration of the influent in water...
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...
Monitoring Well Inventory Using Database Development Software
The South Florida Water Management District (SFWMD) is assisting the Florida Department of Environmental Regulation (FDER) in the establishment of a central repository for statewide hydrologic...
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...
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...
Economics of Hydrothermal Power Development
The overall performance of a hydrothermal power plant with pumped storage is more cost effective than its competitive counterparts such as oil and gas turbine-generators. The operation...
Minicomputers for TVA Reservoir System Operations
A project to develop a Water Resource Management Information (WATERMAIN) system was initiated. The WATERMAIN project identified a broad range of activities, including data collection,...
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...
Numerical Modelling of Bed Evolution in Braided Channel Systems
The overall modelling approach adopted is based on an assumption of quasi-steady flow. The numerical algorithm is based on a split-operator approach, in which the flow energy equation,...
Numerical Simulation of Stratified Flows
The two-dimensional width-averaged equations for flow in estuaries or resevoirs are derived, and the basic assumptions are stated. The heat and salt conservation equations are coupled...
Biological Evaluation of Angled Screen Test Facility
The paper presents comparisons of model and prototype measurements as a means for evaluating the ability of a physical model to reproduce a geometrically complex prototype thermal intake...
Frazil Ice Control Using Air Guns
The design of the J. H. Campbell, Unit 3, Cooling Water Intake in the late 1970's used some new ideas and concepts in response to a strong concern for fish protection at a...
Laboratory Studies for the J. H. Campbell, Unit No. 3, Cooling Water Intake Design
A three-year study sponsored by the Empire State Electric Energy Research Corporation was conducted to determine the overall efficiency of a full-scale angled screen demonstration facility...
Biofouling Control of Water Intake Structures
Biofouling of water intakes can affect condenser performance and availability. This paper discusses four biofouling control technologies: thermal backwash, antifouling coatings, chlorination,...
Stream Research at Coweeta Hydrologic Laboratory
Stream research at Coweeta Hydrologic Laboratory has been directed primarily towards an understanding of long-term responses to logging. Forest logging causes many changes in streams including...
Yakima Remote Control System: Supervisory Control and Data Acquisition
The Yakima Remote Control System is a computerized supervisory control and data acquisition (SCADA) system developed for the operation of the Bureau of Reclamation's Yakima Project in...
Response of Floating Structures in a Directional Sea
A finite element numerical model is presented to predict the behavior of long floating structures in a multi-directional sea. A follow up numerical model analyzes an important but mostly...
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...
