Bayesian Decision Theory and Fuzzy Sets Theory in Systems Operation
Operation of Water Resources Systems involves complex set of human decision. Many of the parameters involved in systems operations are random functions of time. Sometimes, the data needed...
Reservoir Reevaluation in TVA
Demands for the use of dams and reservoirs tend to change after the projects are completed. The Tennessee Valley Authority (TVA) works with State and local groups to try to increase the...
Estimating Earthquake Hazard of Municipal Water Systems
This paper uses the City of Memphis as a case study to present the seismic hazard evaluation of a municipal water delivery system. The horizontal peak bedrock accelerations resulting from...
Effects & Risk Analysis for Time Variable Exposures
The effects of toxicants on organisms in natural settings are a function of both the variations in exposure concentrations and duration of exposure. This paper present analysis procedures...
Water Measurement and Accounting of Lake Michigan Diversion
The diversion of water from Lake Michigan and the Lake Michigan Basin into the Mississippi River Basin has been regulated since the turn of the century. The U.S. Supreme Court Decree of...
Measuring Benefits of Water Supply Projects
Various approaches are used to determine the value of water supply projects. Deterministic methods will lead to biased valuation of additional supplies of water. Calculation of risk premium...
Contracting Provisions to Delay Capital Expenditures and Extend the Use of Available Water Supplies
A contractual means has been established of assuring equitable use of available water supply by the regional participants in the Williamson County Raw Water Line Project. A contract between...
Design of Sampling Networks for Water Table Monitoring
In the application to the monitoring of water tables the presence of temporal and spatial dependence is of crucial importance. Often the network will be used to collect data to estimate...
Instream Habitat Considering Hydro-Peaking
Hydroelectric projects with storage have the characteristic of being able to generate electricity with short notice and to stop generating electricity with equally short notice. This peaking...
Modeling Volatile Organic Transport with Vapor Sorption
A flexible finite element simulation model is developed to predict the movement of volatile organic compounds in variably saturated subsurface regions. The model incorporates both the...
An Economic Evaluation of Property Rights to Groundwater Resources in the State of Texas
The objective of this paper is to evaluate the basis for determination of property rights to groundwater in Texas, and to consider the implications of existing groundwater legislation...
A Comparison of Two Reservoir Projects and Associated Fisheries Impacts
The evaluation of environmental impacts is a critical component of reservoir project development. Impacts to fisheries are especially significant because of the extensive alteration to...
