Risk Analysis of Drinking Water Treatment and Supply Facilities Handling Highly Hazardous Chemicals
Due to increasing public concern of risks from handling highly hazardous chemicals at various facilities, a number of state regulatory agencies, including the State of California, have...
Chandler Canal Fish Screen Facilities
Diversions from rivers must be protected from negative effects on migratory and non-migratory fish species. Diversions to canals often have to be screened to prevent removal and loss of...
Liability of Engineers When Wetlands Laws Change
Engineers who perform wetlands delineations or design facilities in wetlands areas are increasingly sued in court when wetlands laws or regulations change. Owners and developers whose...
Mitigation Wetland Losses for a Major Transportation Improvement Project in New Hampshire
To compensate for 103 acres of wetland impact from a 17.6-mile upgrade of NH Route 101 between Epping and Hampton, New Hampshire, NH Department of Transportation (NHI)OT) and Normandeau...
White River Fish Screen Project Planning and Design
In 1983, Puget Sound Power and Light Company (Puget Power) submitted a license application to FERC for the overall White River Project. One of the elements of the project application was...
The Importance of Plant Community Structure on Form and Function of Created Wetland Systems
If we consider that the creation and the restoration of a wetland system begins with the design of the hydrology, then establishing the form and function of a wetland begins with the design...
The Last Two Extreme Floods in Germany?Analyses and Consequences
The last two extreme floods in Germany occurred in December 1993/January 1994 and January 1995 within the River Rhine basin with both floods having different causes. In a comparison study,...
Aspects of River House Cleaning during Floods
In spite of all the destructive forces of floods, the washing and scouring of polluted bottom deposits during spring floods gives the rivers a new start at the beginning of what is usually...
Combined Flood Hazard Mitigation Techniques for Comprehensive Planning? The Saugus River Coastal Flood Risk Reduction Plan
The development of an alternative Coastal Flood Risic Reduction Plan for the Saugus River was initiated by the Executive Office of Environinental Affairs (EOEA) of Massachusetts in April...
Design Guidelines for UV Disinfection Facilities
Current design methods for UV disinfection facilities depend largely on experience with minimum input design variables, such as water UV transmittance and required disinfection efficiency....
Numerical Modeling of Flows in Ultraviolet Disinfection Channels
Current design methods for UV disinfection facilities depend largely on experience with minimum input design variables, such as water UV transmittance and required disinfection efficiency....
Flood Management Strategies for the Rhine and Maas Rivers in the Netherlands
This paper addresses the above issues, examines the lessons learned, and emphasizes the shift in attention from society on flood management issues. Special attention is devoted to the...
Measurements of Bridge-Scour Depths in Mississippi
This paper briefly summarizes 190 measured pier-scour depths collected dur ing 1942?94 at 22 selected bridges in Mississippi and presents an envelope-curve equation for the data. The envelope-curve...
Design Guidance?Instream and Bank Restoration Structures
Despite an urgent need for river and stream restoration design criteria, little guidance has emerged in recent years. Existing guidance is largely unsatisfactory, promoting empiricism...
Influence of Flooding Events on Suspended Matter Quality of the Meuse River (The Netherlands)
Flooding events of the Rhine and Meuse Rivers have struck The Netherlands in 1993 and 1995. In the Meuse River basin, the river forelands have been widely used for housing and agro-industrial...
Use of Geomorphic Data for Assessing Stream Stability at Bridge Structures
The authors recently completed a statewide bridge scour evaluation for the Nevada Department of Transportation, which included evaluation of the geomorphic processes of bank erosion and...
Observations of Tidal Circulation in Mamala Bay, Hawaii
A comprehensive measurement program, designed to study circulation processes and support hydrodynamic modeling, has been carried out in Mamala Bay on the south coast of the Island of Oahu,...
Design Modification of Water Supply Intakes in Mountainous Regions
Existing river intakes for several water treatment plants in the mountainous areas of western Venezuela have experienced severe difficulties with deposition of sediment. Excessive sediment...
A Knowledge Based System for the Design of Open Channels
The design of open channel facilities often calls for evaluation of a unique set of physical conditions which do not lend themselves to standard designs and textbook solutions. Consequently,...
