Turning an existing bleach manufacturing facility into a printing plant required careful structural design to support a wide range of production processes. The new Daily News facility...

Cable Corrosion in Bridges and Other Structures:
Causes and Solutions
This book provides the reader with basic facts concerning cable corrosion and means to avoid or rehabilitate corrosion damage. Corrosion problems associated with cable-supported structures...

Historical Development of Bridge Scour Evaluations
Scour of bridge foundations (piers and abutments) is the largest single cause of bridge failures in the United States. Conversely, uncertainties of the scour depth at bridge piers and...

Hydraulics of Subsurface Flow Constructed Wetlands
Resistance to flow through subsurface flow wetlands is described by Darcy's law or by Ergun's equation. Both representations are combined with the continuity...

Application of a Hydrodynamic Model in Design of the Kingman Lake Wetland Restoration Project
The U.S Army Corps of Engineers Baltimore District is restoring 45 acres of wetlands within Kingman Lake in the District of Columbia through the placement of dredged material from the...

Hydraulic and Engineering Considerations in Designing Constructed Treatment Wetlands for a Lake Restoration
A 12,600 ha (31,000 acre) hypereutrophic lake in central Florida is being restored by constructing a 2,020 ha (5,000 acre) wetland filter to remove suspended sediments and particulate...

Water Control Structure Choice for Wetland Restoration/Creation
Ducks Unlimited is a non-profit conservation organization, whose mission is to fulfil the annual life cycle needs of North American waterfowl by protecting, enhancing, restoring, and managing,...

Siting of Grade Control Structures
In siting a grade control structure in a stream, hydraulic considerations must be integrated with other important siting factors. A review of several of the important siting factors is...

White River Fish Screen Project?Hydraulic Modeling
In 1983, Puget Sound Power and Light Company (Puget Power) proposed in a license application to FERC for the overall White River Project replacement of the existing fish screens constructed...

Engineering Features of the Red Bluff Research Pumping Plant
In 1995, the construction of the Red Bluff Research Pumping Plant (RBRPP) was completed. The pumping plant is a research facility for evaluating the biological/engineering features of...

Dam Foundation Erosion Study: The Design of a Sidewall Orifice for Simulation of a Free Trajectory Overtopping Jet
This paper describes the design of a sidewall discharging orifice for simulation of a free trajectory overtopping jet. A sidewall orifice discharges through the sidewall of a pipe. The...

Genetic Algorithm Design of Piped Irrigation Systems
The design of piped irrigation systems is a complex matter. In its simplest form it involves the selection of the sizes of pipes and other hydraulic elements so as to ensure that the varying...

Effects of Approach Flow Conditions on Pump Sump Design
An important obstacle to the development of a generalized sump design is the variability of flow conditions in approach areas. The geometry and alignment of the areas immediately upstream...

State of Delaware-Scour Evaluation Program
The Delaware Department of Transportation (DelDOT) is evaluating the potential for scour at bridges which have a National Bridge Inventory (NBI)-Item 113 Code Rating of 6 (scour susceptible)....

Arizona Local Government Bridge Scour Evaluation Study
The Federal Highway Administration has mandated that the scour susceptibility of existing bridges over waterways and open to the travelling public be evaluated. With large numbers of highway...

The Scour at Bridges Management Program in Rhode Island
The Rhode Island Department of Transportation (RIDOT) has developed and implemented a comprehensive two-phase scour susceptibility program for screening and assessment of scour at bridges....

Training for Bridge Inspectors in Stream Stability and Scour
The Federal Highway Administration (FHWA) is now requiring a comprehensive evaluation of bridge scour as part of the National Bridge Inspection Standards (NBIS). FHWA has established January...

Santa Ana River Salt Marsh Restoration: Orange County, California, U.S.A.
As part of the All-River Plan of the Santa Aria River, the 92 acre Santa Ana River Marsh (Marsh) was constructed at the Pacific Ocean outlet in Orange County, California. This project...

Grade-Control Structures for Salt River Channelization
Soil cement grade-control structures have been designed and constructed in conjunction with channelization projects along the Salt River in Phoenix, Arizona. The structures were designed...

A Surface Collection Design Approach on the Lower Columbia River
Surface collection and bypass of downstream migrating juvenile salmon has the potential to help improve the survival of the Columbia River salmon population. However, surface passage on...
