Wind Generated Wave Resuspension of Sediment in Old Tampa Bay, Florida
Vertical profiles of velocity and suspended-solids concentration were measured at a scientific instrumentation platform in Old Tampa Bay during the passage of a cold front in March 1990....
Local Resources in Developing Country Water Supplies
Maximizing the use of local resources in water supply projects can expand markets for locally produced equipment and materials, reduce exports and minimize expenditures of hard currency...
Management and Institutional Considerations in Selecting Appropriate Technologies in Water Supply and Sanitation
Rural water supply and sanitation systems in developing countries have had an unacceptably high rate of failure or reduced use. Development planners have not sufficiently considered the...
Visualization of a 3D Model of Chesapeake Bay
A three-dimensional (3D) numerical hydrodynamic and water quality model (WQM) of the Chesapeake Bay and its major tributaries has been developed by the US Army Engineer Waterways Experiment...
Rainfall-Runoff Modeling in a Small Urban Watershed
Knights Branch watershed is located in Dallas, Texas, and it covers an area of about 5 mi2 (13 km2). Due to...
Numerical Modeling of Proposed Channel Designs (J. F. Baldwin III), California
Ship simulator studies of proposed improvements to navigable waterways are a very important part of any assessment. The John F. Baldwin Channel (JFB) Project (Phase III) is a ship channel...
Who Pays for the Unexpected in Construction??The Lawyer's Point of View
Encountering the unexpected is to be expected - it is one of the risks inherent in construction. While encountering the unexpected cannot be completely prevented, steps to (1) reduce the...
Central Artery (I-93)/Tunnel (I-90) Project
This paper is intended to provide an overview of the Boston Central Artery/Tunnel Project (CA/T) Project; a $4.9 billion USD interstate highway constructed underground through a densely...

Economic Impact of Earthquake Effects on the City of Everett's Lifelines
The economic effects of lifelines failures, caused by three hypothesized earthquake scenarios, in the city of Everett, Washington are estimated. The project team consists of lifeline seismic...
Cross-Impact Analysis for Lifeline Interactions
A probabilistic method to evaluate the seismic risk of urban lifeline network systems is presented with emphasis on the interactive aspects of lifeline earthquake disaster. First, the...
Fuzzy Reasoning for Earthquake Damage Assessment of Large-Scale City Gas Systems
A method for earthquake damage assessment is proposed for a large-scale city gas system. Since lifeline systems are usually laid in a large area and are composed of a number of component...
