Hydropower Goes Downtown
Beneath a busy street in Southern California seems an unlikely location for a small hydroelectric generating plant. However, located just below El Segundo Boulevard in the town of El Segundo...
Design of Seepage Control Systems for RCC Dams
As the reservoirs of the first generation of roller compacted concrete (RCC) dams have been filled, several have exhibited significant amounts of seepage, a fact that has been of concern...
Quality Control/Inspection�Upper Stillwater Dam
Roller compacted concrete construction, or RCC, is a relatively new method of constructing concrete dams and involves placing and spreading no-slump concrete in horizontal layers and compacting...
Quality of Works in RCC in France: A Contractor's Solution
Bec Freres S. A. , a French dam contractor, introduced the technique of roller compacted concrete (RCC) into France. The first two French RCC dams were built as a result of a program of...
RCC in Dams in Australia
The design, construction and performance of the first three dams constructed in Australia, using RCC are described. Aspects covered in the paper include designing for zero cohesion between...
RCC Pavement Construction and Quality Control
In October 1986 a 16,500 sq yd (14,300 sq m) roller-compacted concrete (RCC) pavement tank hardstand, the first of its kind in Europe, was built for the U. S. Army at Harvey Barracks in...
A Simple Nonpoint Source Groundwater Quality Management Model
A model is examined which efficiently produces information required by decision makers to assess water quality tradeoffs associated with alternative groundwater protection strategies,...
An Operations Advisor for Regional Water Management
The application of artificial intelligence techniques was evaluated for implementation for water control structure operations at the South Florida Water Management District. After an analysis...
Design of the Oasis Advisory System
Once the decision was made to develop an advisory system for the operation of water control structures within the South Florida Water Management District, a schedule of activities leading...
Assessing WQ Impacts Using a Hydraulic Model
Engineering projects may cause water quality impacts in estuarine systems. It is important to assess those impacts during the planning phase of the project so that mitigation measures...
Water Quality Assessment and Management System in Regulatory Environments
State water quality regulatory agencies need to prioritize water bodies for program actions so that agency workload can be determined and resources allocated in order to achieve positive...
Spreadsheet Applications in Water Quality Management
The state regulatory environment requires simple, quick, easy to use and maintain water quality analysis tools. Therefore, for the evaluation of toxic substances, a new approach towards...
Rehabilitation Strategies for Urban Drainage Systems?A European Perspective
Rehabilitation of urban drainage system is needed in many old European cities. This is in part due to the required structural upgrading of the existing sewerage system. But rehabilitation...
Optimal Pump Operation Using Nonlinear Programming
This paper focuses on the operational control problem of determining the optimal pump operation policy for a given distribution system. The optimal pump policy is defined as that schedule...
Rolling Incinerators
The Illinois Environmental Protection Agency (IEPA) is using a mobile incinerator to clean up a former oil and solvent storage/transfer operation which was badly contaminated. The benefits...
Design for Variable Frequency Drive Applications
This paper presents fundamental design criteria used to evaluate the operational and economic feasibility of installing a variable frequency drive (VFD) on a petroleum products pipeline....
Computer Control for Salt Lake City Water System
In 1978 the Department of Public Utilities in Salt Lake City began to develop a computer system to aid in the operation of the water system. The Department of Public Utilities computer...
Geotechnical Aspects of Karst Terrains
Exploration, Foundation Design and Performance, and Remedial Measures
The presence of solution cavities in karst terrains poses some unique problems in site exploration, design of foundations, and in remediation of problems with existing structures. Case...
