Design of Groins on the Middle Rio Grande
The Albuquerque Projects Office of the Bureau of Reclamation wanted to use groins in place of revetments at two sites on the Rio Grande. The Bureau of Reclamation has limited experience...
Hydraulic Features of Flexible Curtains Used for Selective Withdrawal
Flexible curtain barriers are being investigated as a way to modify power penstock intakes to achieve selective withdrawal. The curtain barrier controls the elevation from which water...
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...
A National Bridge Scour Data Collection Program
A study to collect and analyze field measurements of bridge scour is being conducted by the U.S. Geological Survey in cooperation with the Federal Highway Administration. The primary objective...
Appropriate Technology in Infrastructure Development and Management
Infrastructure management principles apply to appropriate technologies used for hydraulic structures. However, some of the principles are more culturally sensitive than others, mainly...
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...
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...
Design of High Capacity Spillways for Ritschard Dam, Colorado
A hydraulic model investigation was conducted by the Bureau of Reclamation to assist in designing the hydraulic structures associated with Ritschard Dam. Ritschard Dam will have a labyrinth...
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....
Incipient Motion Criteria Defining Safe Zones for Salmon Spawning Habitat
Approximately 70% of the City of Seattle's water supply is drawn from the Cedar River. Between 200,000 and 400,000 sockeye salmon spawn annually in this partially dewatered...
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...
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...
Redondo Beach Thermal Study
Thermal tests were conducted in a 3D physical model of Redondo Beach King Harbor to simulate power plant cooling water intake and discharge into the harbor. Tests were conducted to determine...
Design of a Stratified Cooling Channel
Cooling ponds are used for managing waste heat discharges. Cooling ponds are, however, expensive to construct and operate. A cooling channel is studied as an alternative means of managing...
A Microcomputer-Based System for Two-Dimensional Flow Modeling
An integrated, microcomputer-based system has been developed for simulation of two-dimensional, unsteady, free surface flows. The system consists of a finite-element mesh generation code,...
Model Study of an Intake Structure
To increase the delivery capacity of an existing gravity-feed water supply pipeline in Orange County, California, modification of the existing structure and placement of a booster pumping...
Physical Model of a Floating Trash Boom to Control Aquatic Weeds at the TVA Widows Creek Fossil Plant
The Tennessee Valley Authority (TVA) Widows Creek Fossil Plant seasonally encounters adverse accumulations of aquatic weeds at the intakes of the condenser cooling water pumps. To reduce...
Tracking Cold Water in a Large Reservoir System
