Capacity Expansion of Water Distribution Systems?A Case Study
Capacity expansion and necessary capital improvements to meet the water supply demand for years 1990-2020 for the U. S. Route 1 corridor development from South Brunswick to Princeton,...
Embankment Overtopping?Case Histories
Because many existing dams are subject to overtopping, there is a need to understand embankment behavior during an overtopping event. Understanding of this behavior will allow evaluation...
Effects of Reservoir Regulation on Channel Morphology
A case study is presented in which such a multidisciplinary approach was used to evaluate the impacts of regulated outflows from the recently completed Warm Springs Dam Project (Sonoma...
Factors Influencing Conveyance Efficiency
Losses from a water distribution system are inadequately defined by reference to only the gross conveyance efficiency (Ec) of the system. The various unavoidable and avoidable losses that...
Comparison of Surge and Continuous Flow Irrigation in California
With the closure of the Kesterson National Wildlife Refuge to drainwater disposal and the pending limits on tailwater flows to the San Joaquin River, decreasing deep percolation is of...
Feasibility of Weather Modification for California's State Water Project
The California Department of Water Resources (DWR), in the mid 1950's, contracted with some 30 water agencies to eventually furnish about 4. 2 million acre-feet (MAF) of water...
Management Challenges Affecting Agricultural Reuse of High-Strength Food Processing Wastewaters
Land treatment of high-strength food processing wastewaters is a viable pollution control technology. Due to the high-strength characteristics of these wastewaters, effective site management...
Runoff Model for Watersheds of Nonhomogeneous Characteristics
A watershed of any configuration, topography, and spatial distribution of cover, soil and channel characteristics is described as a plannar grid. Time-varying precipitation is applied...
Are Soil Moisture Accounting Models Needed for the Real Time Forecasting of River Flows?
The difficulties inherent in using conceptual rainfall-runoff models in conjunction with filtering techniques, for the real time forecasting of river flows, are reviewed. The issue of...
Design Rainfall for Pennsylvania
The most commonly used source of rainfall estimates is the U. S. Weather Bureau Technical Paper 40. A more detailed study of Pennsylvania storms was conducted in 1970 under the sponsorship...
Design Storm Selection for Stormwater Management Master Plans
The design rainfall event is an important performance standard for a stormwater management master plan. A stormwater master plan for Virginia Beach, Virginia, is used as a case study to...
Feasibility Studies of Flood Warning-Response Plans
Local flood warning-emergency preparedness plans consist of hardware, technical activities, and formal and informal inter- and intra-organizational arrangements and commitments to performance...
Modeling Coal Pile Leachate - A Case Study
Ground water transport of coal leachate from an existing unlined coal storage pile was modeled using the USGS 'Computer Model of Two-Dimensional Solute Transport and Dispersion...
Improved SWMM Applications for Stormwater Management Master Plans: A Case Study of Virginia Beach, Virginia
A case study of a recent master plan for a 16. 5 sq mi watershed in Virginia Beach, Virginia is presented to illustrate stormwater master planning approaches. The analysis showed that...
An Application of EPA EXTRAN Model to a Flood Management Study in South Florida
In performing the flood management studies, somewhat unique concerns in South Florida are the backwater conditions due to tidal or non-tidal tailwater, flow reversals from project canal...
Development, Use, and Synthesis of S-Graphs
A study to identify S-graphs from the southwestern United States has been completed. This study has resulted in the compliation of 53 S-graphs, documentation of some of the watershed characteristics,...
Time of Concentration in Small Rural Watersheds
A comparison was performed between the exponents of the independent variables L, S and i of the four-parameter time of concentration equation and eleven frequently encountered equations....
Optimization of Complex Hydrologic Models Using Random Search Methods
The primary objective of automated calibration of complex conceptual hydrologic simulation models is to find the global optimum of a specified response surface. While direct search techniques...
A Comparative Study of Different Base Isolators
A comparative study of the effectiveness of four different base isolators is carried out. The structure is modeled as a rigid mass and the accelerograms of the North-South component of...
Wind-Induced Response of a Tall Building and Comparisons With Wind Tunnel Predictions
This paper describes the measured wind-induced response of a tall office tower and comparisons made with wind tunnel studies of the building. The use of an innovative structural system...
