Roller Compacted Concrete Mix Design for Pamo Dam
Pamo Dam is designed as a 265 foot (81M) high gravity dam that will be located on the Santa Isabel Creek in San Diego County, California. RCC volume will be approximately 491,000 cubic...
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...
Regulatory and Environmental Issues of the Chisman Creek Superfund Site
This paper discusses the regulatory and environmental issues arising from the response to the Record of Decision (ROD) for the Chisman Creek Superfund Site in York County, Virginia. Field...
Frequency Domain Site Response with Pore Pressure
A frequency domain analysis for seismic site response and liquefaction potential is developed. The analysis is based upon a nonstationary random vibration theory. The model uses an effective...
A Stochastic Model for Low-Cycle Elastic-Plastic Fatigue Crack Growth
In this paper a stochastic process approach is considered to represent the random nature of the low-cycle (elastic-plastic) fatigue crack growth process. A semi-Markov renewal model is...
Pore Pressure Development: Probability Analysis
The development and subsequent dissipation of excess pore pressure, p in a soil deposit subject to an external load is examined using probability concepts that account for uncertainties...
Time Series Analysis of Wind Pressures on Low Buildings
A new methodology for the description of local wind pressures on the building envelope of mono-sloped roof buildings by using time series analysis is described. A simple AR(1) model has...
Pressures on Prisms in Turbulent Shear Flows
Experimental results are presented which show that Melbourne's 'Small Scale Spectral Density Parameter,' S, controls the negative pressures on the...
Effect of Air Gap on Platform Reliability
A simplified reliability study of the effect of lateral wave forces impacting the deck of a fixed platform is presented. The reliability of the deck legs, considered the primary resistance...
Expert Systems for Drought Management: A Case Study
This paper describes the development and application of a computer model used by the Seattle Water Department (SWD) for operations during drought. This model provides guidance for initiating...
Irrigation-Induced Contamination Problems
At the Kesterson National Wildlife Refuge in the San Joaquin Valley of California, severe fish and wildlife problems (waterfowl mortality, embryonic deformities, and reproductive failures)...
Extent of Water Quality Effects of Dams?A National Viewpoint
An overview of phosphorus impacts on impoundments, a subset of the contents of the Dam Water Quality Report is presented. The U.S. Environmental Protection Agency (EPA) is the lead investigator...
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,...
Tidewater Virginia's Water Supply Problem: Implications for State Water Management
Attempts to expand water supply in response to continuing urban growth in Virginia's Tidewater region has produced prolonged conflict among the area's local governments...
Regional Water Cooperation: An Alternative to Interbasin Transfer
Due to political and environmental impacts interbasin transfer is often regarded as an undesirable alternative for water supply development. However, water authorities will pursue interbasin...
Conflict Over Urban Water: An Economic Perspective
Water conflicts in the East are associated primarily with infrequent proposals by public water systems to move water across political boundaries. Also, most conflicts arise among political...
Socio-Economic Issues in Financing Water Resources Development Compared to Non-Structural Alternatives
Like the hydrologic cycle, financing water resources development requires a holistic view of the technical, legal, institutional (social and economic) factors before alternative selection....
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...
