Evaluation of Embankment Erosion at TVA's Chickamauga Project
Studies were made to evaluate the extent of erosion to be expected under probable maximum flood (PMF) conditions. The erosion studies were made using the EMBANK computer program. The results...
Bridge Scour Vulnerability Assessment
Although the failure of the New York Throughway bridge over Schoharie Creek in 1987 has focused national attention on scour related failures, other failures reinforce the need for implementing...
Evolution of Appropriate Technology
Although appropriate technology has been practiced since the beginning of people on earth, the inventiveness of the 20th century is forcing engineers (and others) to look at the multitude...
Health Benefits From the Use of Appropriate Technologies in Water Supply and Sanitation
Research on selected diseases in developing countries has found significant health impacts from water supply and sanitation interventions. Sanitation, personal and domestic hygiene, and...
Modeling of Wetland Hydrodynamics and Transport in Coastal Louisiana
Modeling of hydraulics and transport of large wetland systems poses critical decisions between resolution of the complex geometry of a wetland and the testing required to meet study goals....
TABS-2 Application to Kawainui Marsh Flood Control
The TABS-2 mathematical modeling system was used to evaluate the effectiveness of alternatives designed to eliminate flooding problems in the Kawainui Marsh located in Kailua on the east...
Bridge Scour Research Needs
This paper presents a summary of the Federal Highway Administration (FHWA) priority research emphasis on bridge scour, sedimentation, and stream stability problems. The most persistent...
Management and Institutional Considerations in Selecting Appropriate Technologies in Water Supply and Sanitation
Rural water supply and sanitation systems in developing countries have had an unacceptably high rate of failure or reduced use. Development planners have not sufficiently considered the...
Education, Research and Training for Appropriate Technology
Much has been written about appropriate technology (AT) and how to accomplish it. This paper adds to that literature with specific ideas for education, training and research programs and...
Appropriate Technology in Hydraulic Engineering
Appropriate, and successful, technology transfer is contingent upon the simple dictum: technology transfer is context dependent and context specific. Optimum success in the transfer of...
The Role of Computational Fluid Dynamics in Hydroturbine Analysis
Prospects of developing comprehensive methods of computational fluid dynamics for the analysis and design of new generation of hydroturbines are considered. Unique requirements for this...
Dam Break Analysis for a Series of Dams Using the HEC-1 and DAMBRK Computer Programs
The HEC-1 and DAMBRK computer programs were developed by the US Army Corps of Engineers, Hydrologic Engineering Center (HEC) [3] and by the National Weather Service (NWS) [4], respectively....
River Dike Design Using a Numerical Model Approach
The preliminary design of a dike field at Redeye Crossing on the Mississippi River (Baton Rouge, Louisiana) is discussed. The TABS-2 modeling system was used to develop a two dimensional...
Issues and Challenges Facing the Effective Delivery of Scientific Visualization
The availability of economical hardware and software products for scientific visualization has stimulated implementation of scientific visualization within high performance computing environments....
A Modular Visual Interface for Computational Fluids Forecasting
A forecasting system is under development for predicting the three-dimensional physical features (e.g. velocity, temperature etc.) of large water bodies. Visualization and interface development...
Visualization of Grids and Flow Fields for CFD Data
This paper will address visualization of grids and flow fields for computational field simulation. Specifically, we will present results and demonstrations of surface and grid generation...
Introduction, and Analysis of Survey?Preliminary Report of Task Committee on Recommendations for Standards in Hydraulics
To help formulate its recommendations for future standardization of tasks in hydraulic engineering, the Task Committee conducted a survey of practicing engineers. This survey indicated...
Existing U.S. Standards in Hydraulic Engineering
The Task Committee on Recommendations for Standards in Hydraulics confined itself to topics that are used in hydraulic computations or design. Thus numerous standards related to size,...
Foreign Hydraulic Standards and Guidelines
Standardization in Europe is propelled by the incentive to achieve harmonization of design, testing, inspection and certification methods for an internal market among eighteen European...
Preliminary Recommendations from the Task Committee on Standards in Hydraulics
The Task Committee on Standards in Hydraulics has been given the responsibility of recommending whether or not the American Society of Civil Engineers (ASCE) should formulate standards...
