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...

Flood Control Design for Development on Alluvial Fans
Hydrology, debris production, sediment transport and hydraulic studies were conducted to provide flood control for a development within an alluvial fan floodplain. Innovative techniques...

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...

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...

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...

Environmental and Hydraulic Considerations in the Design of a Circulating Water Cooling System
Environmental considerations play an important part in the design of a condenser cooling system. A once-through system may require assessment of a combination of events to determine the...

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...

Design of a Self-Regulating Flap Gate
The objective of the research reported here is to improve the design of a flap gate whose function is to maintain a constant upstream water level over a wide range of flow rates. The self-regulating...

Experimental Model Study of Over and Under Baffles
A hydraulic model study of a chlorine mixing channel was conducted at the Hydraulic Research Laboratory of the City of Los Angeles. An arrangement of over-under baffles was used to facilitate...

Application of a Generalized Risk Dynamic Model to a Spillway Design Flood
Risk analysis can provide a logical basis for selecting the optimal design capacity of a flow conveyance hydraulic structure for the least total cost or specified non-exceeding risk levels....

TransAct: An Interactive Transient Analysis Program for Pipelines
The program TransAct is designed to analyze a wide range of transient responses that may have been caused by a complex combination of control actions. For example, there may be the simultaneous...

Model Study of a Hurricane Surge Barrier Gate Valve
Physical model studies were conducted to determine the hydraulic performance of a unique vertical butterfly-gated structure. These studies were also used to determine the torque on the...

Model Studies of Outlet and Intake at McCook Reservoir
Two separate physical models were used to investigate the outflow and inflow into the proposed McCook Reservoir. The proposed reservoir will be located in McCook, Illinois, and will serve...

Loose Riprap Grade Control Structure Design
The Soil Conservation Service has been using loose riprap grade control structures based on the equal energy concept for several years with mixed success. Previous model studies resulted...

Vortex at Hydraulic Intakes with Asymmetric Approach Flows
The formation of vortices at intakes can disrupt normal operating procedures and damage hydraulic machinery. Asymmetric approach flow and a protruding pier (normal wall) contribute to...

Improved Intake Design for Downstream Migrating Fish at Hydropower Plants
Fish guidance efficiency of screens is a function of the submergence of a hydropower intake. The submergence of an intake can be reduced through the use of intake extensions or guides...

Seawater Delivery for Use in Aquaculture Development
Seawater is used extensively in industrial and aquacultural developments world wide, and aquaculture in particular requires large quantities of seawater. Development and design of facilities...
