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...

Field Measurement of Hydrodynamics and Sediment Transport of the Mississippi River at Old River
Two detailed field surveys of the hydrodynamics and suspended sediment transport of the Mississippi River at the Old River Control Structure complex were completed in February and June...

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...

Probabilistic Aspects of Hydroproject Maintenance
A survey of operation and maintenance personnel in the hydraulic structures sector was conducted to learn about the present maintenance approach and the perception of the probabilistic...

Reliability Assessment Method for Flood Forecasts
Peak discharge predictions produced by rainfall-runoff models and used by flood warning and preparedness agencies are subject to uncertainties in the input data, model parameters, and...

Conventional Storm Drainage Which Recharges the Groundwater
Since the demand for water is on the rise, more resourceful means of retaining and controlling the release of stormwater is needed. This retained stormwater may then be used for aesthetic...

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...

Temporary Facilities?Making It Happen, Organization and Logistics
As construction projects become larger, more complex and are constructed both faster and under more adverse conditions--the use of temporary facilities is more prevalent. Temporary facilities...

The Benefits of U.K. Guidance for Temporary Works
In British contracts the Contractor is responsible for the design and execution of temporary works unless the Design Engineer or the Client expressly instruct how the work is to be undertaken...

Legal Principles and Theories
Legal issues are intertwined with all aspects of the technical considerations relating to temporary structures. This paper presents an introduction to the legal theories which relate to...

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 Structures for Protection and Access
Temporary Structures in Construction Projects (TSC) are utilized for three (3) purposes A. Support (of the structure being built or adjacent structures or utilities) B. Protection (of...

Fall Protection & Debris Containment During Construction
The purpose of this paper is to review the current practices in the United States for both fall protection and debris protection during high rise construction. A performance comparison...

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...

Performance of a Prestressed Rigid Frame During Removal of Column 6W from I93 in Boston, Massachusetts
The first phase of the suppression of Boston's Central Artery included the Early Viaduct Construction in the Central Artery North Area. This project required that Column 6W...

Permanent Structure as Part of the Underpinning System for Boston's Central Artery
The Central Artery, a major six lane structural steel viaduct, has been one of Boston's most significant roadways over the past three decades. Increasing congestion, accidents,...
