The Thames Water Authority has developed an integrated strategy for providing water supplies to London into the 21st Century. At the core of this strategy is the construction of over 60...
Computer Control of Houston's Water System
The City of Houston's Central Surveillance and Control System utilizes dual host computers and over 100 'smart' Remote Terminal Units to control...
Optimal Control of the West Parisian Area Water Supply Network
The West Parisian Area regional office of Lyonnaise des Eaux has been equipped with computer-aided optimal decision-making software, using daily water demand forecasts. This tool calculates...
Water Quality Management During Low-Flow Periods: A Systems Analysis Approach
Water quality objectives may require water managers to consider deviations from original project purposes to provide downstream water quality maintenance during low-flow periods. The decision...
Reliability of Bank Protection Works Subject to Erosion
Sediment movement and changes of bed levels in natural rivers are non-stationary processes. The design of protection works for structures against erosion should account for the time dependency...
History of the Federal Interagency Sedimentation Project
Since 1939, the date of the Project's inception, the team has operated under the direction of two lead agencies - the U.S. Geological Survey and U.S. Army Corps of Engineers....
Prediction of Time Development of Local Scour
The prediction of the time development of local scour is commonly solved by means of model tests. A brief description of the time-scale and the relation between the time and the scour...
Ports '89
This is a collection of the technical papers presented at the triennial Ports '89 Conference held in Boston, Massachusetts in May 1989. Authors, although predominantly from...
Boundary Element Methods in Structural Analysis
Tutorial and state-of-art aspects of the Boundary Element Method (BEM) are combined with applications in structural analysis in order to provide information about the advantages of this...
Electricity From Air
After a decade of research and dozens of feasibility studies at sites around the country, the first Compressed Air Energy Storage (CAES) plant in the U.S. is under construction at McIntosh,...
Breakwater Choices
Most of the maritime breakwaters built throughout the world are of the rubble mount type, with a protective armor constructed of artificial blocks. Despite the multitude of different shapes...
Bullwinkle
The 1989 Outstanding Civil Engineering Achievement is an offshore oil production platform named Bullwinkle, a structure in the Gulf of Mexico that is taller than the Sears Tower, shaped...
Analysis of Local Scouring
An understanding of local scouring is very important for the safety and integrity of hydraulic structures. The location, shape, and magnitude of the scour hole is a function of dynamic...
Predicting Human Instability in Flood Flows
The delineation of high flood hazard zones within a flood plain is usually independent of the parameters that constitute a life threatening situation. In order to define human instability...
Application of Hydraulic and Sediment Transport Principles in the Design of Tidal Exchange Structures
This paper presents a procedure for the analysis and design of tidal exchange structures, such as tidal gates and training dikes. In lieu of over generalized theories or complicated modeling...
Water Quality Monitoring of Highway Construction
The primary objective of water quality monitoring, as it relates to highway construction, is to obtain quantitative information to ensure that runoff from the construction site does not...
Groins and Vanes Developed Basing Upon a New Concept of Bank Protection
At curved bends, scour at the outer bank always accompanies deposition at the inner bank. A highly efficient river course for flood flow is considered to have a small lateral gradient...
Beach Erosion Protection Methods: Case Study of Dar City Tanzania
Coastal Tanzania has been experiencing severe beach erosion. Beach erosion is much felt in coastal cities like Dar es Salaam, Tanga etc. Beach erosion in Dar es Salaam has caused damage...
State-of-the-Art Report: Mexico
Design recommendations for groins and spur dikes are presented. For groins the most important ones are: to build them with sloping crests, orientated downstream and maximum spacing of...
Relief of an Urban Storm Drainage System
The Peaks Branch storm sewer system was designed in the 1930s to drain 5.7 square miles of East Dallas. Subsequently, development blocked the emergency overflow paths and many areas are...
