This paper introduces the concept of utilizing underground storage to minimize both the initial cost and the long-term maintenance and operation costs of multiple pump stations for a freeway...

Optimizing Regional Detention Basins for Price Expressway
Stormwater runoff from the drainage area contributing to the Price-Santan Freeway is captured in regional detention basins which require a series of pump stations for evacuation. With...

New Lessons About the Hydraulic Performance of Highway Storm Sewer Inlets
Laboratory experiments were performed with highway storm water curb inlets to 1) reduce the oblique standing wave that extends into the highway from the downstream side of the inlet and...

Bridge Scour Vulnerability Assessment
Although the failure of the New York Throughway bridge over Schoharie Creek in 1987 has focused national attention on scour related failures, other failures reinforce the need for implementing...

Bridge Inspections Related to Bridge Scour
The failure of the Silver Bridge over the Ohio River in Point Pleasant, West Virginia, on December 15, 1967 resulted in the establishment of the National Bridge Inspection Standards (NBIS)...

Evolution of Appropriate Technology
Although appropriate technology has been practiced since the beginning of people on earth, the inventiveness of the 20th century is forcing engineers (and others) to look at the multitude...

Health Benefits From the Use of Appropriate Technologies in Water Supply and Sanitation
Research on selected diseases in developing countries has found significant health impacts from water supply and sanitation interventions. Sanitation, personal and domestic hygiene, and...

Modeling of Wetland Hydrodynamics and Transport in Coastal Louisiana
Modeling of hydraulics and transport of large wetland systems poses critical decisions between resolution of the complex geometry of a wetland and the testing required to meet study goals....
