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...

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...

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...

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...

Gropps Lake Dam
Gropps Lake Dam has a concrete ogee spillway with earthen abutments at either end of the spillway. The dam features an internal drainage system, outlet works, an energy dissipator, a steel...

A Knowledge-Based System for the Environmental Design of Waterways (ENDOW)
Knowledge-based software systems accept problem descriptions from users and apply logic in order to generate a solution or solution set. These systems function over very narrow problem...

Verification of WASURO Using the Puerto Nuevo Physical Model Study Results
The Jacksonville District, US Army Corps of Engineers, used the hydraulic design computer modeling program, WASURO, for preliminary design of the Rio Puerto Nuevo Flood Control System....

Detention Basin Design to Control Flood Volumes
A desk-top method is presented for hydraulic design of detention basins. The main objective is to control the flood volume rather than the peak discharge. The method is based on the pre-determined...

Hydraulic Roughness and Sediment Yield in Wheel Ruts on Forest Roads
Clear water flow and sediment yield from simulated wheel ruts in a forest road were measured at five different sites in the Northern Rocky Mountains. These measurements provided information...

Liability Insurance Coverages for Designers of Temporary Structures
A recent survey completed by the American Consulting Engineers Counsel (ACEC) indicates that in 1990 approximately 40 claims occurred per 100 firms. There also is an indication that claims...

Limit States Design of Wooden Formwork for Concrete Walls
Load and resistance factors are developed for ultimate limit states design of wooden formwork components for concrete walls when the lateral concrete pressures are computed using the ACI...

FHWA'S Bridge Temporary Works Research Program
The Federal Highway Administration (FHWA) has developed a research program to address bridge falsework design and construction. This resulted from the collapse of the Route 198 bridge...

Development of Standards for Slipform & Jumpform Works
Review of past work indicates substantial effort has been made to publish construction standards and guidelines for slipforms but published material pertaining to jumpforms is scarce....

Temporary Lateral Support System for Historic Building Facades in Boston
This paper describes a system of vertically cantilevered structural steel trusses, designed by the author, that provided temporary lateral support for a group of five and six story, 120...
