Old Ideas, New Applications: Expanding the State of the Practice
This paper describes three projects in which analytical tools were developed to assist decision makers in operating large-scale water resource systems. Position analysis models were developed...
Fuzzy Sets in Civil Engineering?A Tutorial
This tutorial is an introduction to the theory of fuzzy sets and its applications in Civil Engineering, including its use within the framework of knowledge-based systems. The techniques...
Tutorial: Fuzzy Set Theory in Water Resources Systems
Principles of using fuzzy set theory (FST) to describe imprecision (or vagueness) in water resources systems are provided. The main tool of FST, the membership function, measures the degree...
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...
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...
Abilene, Texas, Flood Control Study?Cast History
The Corps of Engineers, Fort Worth District, is currently performing a study of flooding problems of Abilene, Texas. This is the first study under the General Investigations authority...
Conflict Resolution, Reallocation and Management of Lake Texoma Resources
From its inception, Lake Texoma has created conflicts among users of its natural resources, including hydropower, water supply, flood control, and recreational users. Many attempts have...
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...
Water Resources: Transfer of Development Rights
This paper addresses conflicts regarding development, land owners rights, accepted land development management practices, and community or public rights. It includes such issues as the...
Predicting Effects of Global Climate Change on Reservoir Water Quality and Fish Habitat
This paper demonstrates the use of general circulation models (GCMs) for assessing global climate change effects on reservoir water quality and illustrates that general conclusions about...
Spatial Averaging of Statistically Anisotropic Point Conductivities
This paper presents a new technique to compute the mean, variogram and cross-variograms of the components of block conductivity tensors given the statistical distribution of point conductivities....
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...
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...
Applications of Probability Matrix Methods for Texas Reservoirs
Probability matrix methods are a class of procedures which were generally developed from P.A.P. Moran's Theory of Storage. In essence, probability matrix methods are a means...
Marginal Cost Techniques for Reservoir Optimization
Selection of the optimum water supply reservoir from multiple reservoir sites under consideration in a water resource planning study for the Houston Metroplex evaluated hydrology, engineering,...
Conjunctive Management of the Edwards Aquifer and Connected Surface Streams in South Central Texas
The Edwards Aquifer is a long, narrow conduit through which water moves underground across parts of South Central Texas. Increased use of water from the Edwards Aquifer has been substantial...
Managing an Interruptible Water Supply
The Lower Colorado River Authority has developed a plan for the management of an interruptible water supply for demands which do not require a firm commitment of specific amounts of water....
