Turbulence and Reynolds Stress Distribution in a Natural River
Turbulence characteristics of ambient flow velocities and their comparison with those generated by the movement of barge traffic within the channel border area in a navigation waterway...

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...

Uncertainty Quantification in Water Distribution Parameter Estimation
Calibration for water distribution system model parameters is usually undertaken with a minimal amount of field measurements so additional pseudomeasurements are assumed. Both the actual...

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...

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...

Daily Drought Monitoring by the Use of Existing Hydrologic Records
To manage water efficiently in case of drought, an effective drought monitoring method has been of interest. Drought durations and their conditional probabilities are estimated by applying...

Drought-related West Tennessee Channel Bank Failures
Massive bank failures occurred in 1988 along a 14-kilometer reach of the lower Obion River channel in Dyer County, West Tennessee where the river flows through an abandoned Mississippi...

Fluvial Recharge of Sand Mining Pit
Accuracy in modeling fluvial processes becomes increasingly important as development occurs along waterways. The FLUVIAL-12 (1, 2) model is used to simulate the recharge of sand mining...

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...

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,...
