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...

PC Versatility in Modern Hydraulic Laboratory Data Acquisition Systems
Recent and newly emerging developments in low cost (personal) computing have enabled engineers to implement sophisticated data collection and analysis techniques on computing platforms...

Data Acquisition Systems for IBM Compatible System
Portable data acquisition systems composed of IBM compatible PC/XT/AT computers and analog to digital conversion cards can be configured with relative ease. These systems have the flexibility...

Computerized Data Acquisition for an Undergraduate Hydraulics Laboratory
Basic hydraulics principles and the operation of certain hydraulic systems can be effectively demonstrated with the aid of relatively inexpensive data acquisition and analyses systems....

Enhancing Effluent Water Quality of Sedimentation Basins Using Constructed Wetlands Technology
The Tennessee Valley Authority (TVA) has constructed twelve wetlands to treat acid drainage at reclaimed coal mines and fossil-fueled power plants. These wetlands are designed primarily...

3-D Free Surface Flow Model Verification
This paper is intended to achieve two objectives: (1) providing the readers and participants of the 1991 ASCE National Conference on Hydraulic Engineering with background information about...

Computerized Hydraulic Modeling?A Case Study
A hydraulic model study is being conducted at the Alden Research Laboratory, Inc. (ARL), to study the effects of adding a hydroelectric generating station at the site of an existing lock...

Detecting the Twin Vortex Draft Tube Surge
Experiments were performed to investigate a twin vortex draft tube surge in a homologous model and the prototype 700-MW turbines installed at the U.S. Bureau of Reclamation's...

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...
