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...

Bayesian Decision Principles for Flood Warnings
A Bayesian theory of flood warning systems has been formulated. The theory offers principles for mathematical modeling of warning systems. The objectives of modeling are (i) to find the...

Comparison Between the Field and Laboratory Measured Properties of a Clay Liner
Hydraulic conductivity (K) and bulk density (BD) of an experimental clay linear were evaluated at a large number of locations using standard methods. They were then compared to laboratory...

Measuring Performance of Clay Containment Barriers
Clayey soils compacted to engineering specifications are widely used as structures for hydraulic containment. Current applications include landfill liners, landfill covers, pond liners,...

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...

Non-Point Source Contamination of Aquifers
The paper discusses a new method for simulating the movement of contaminants from a diffuse source at the soil surface through a variably-saturated porous medium. The method accounts for...

Groundwater Modeling of the Tustin/Irvine Basin
This paper describes the results of groundwater modeling in the Tustin/Irvine basin situated in the southeastern portion of the Tustin plain, which is the the southern extension of the...

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....

Application of the GRASS Geographic Information System in a Sensitive Environment of the Arkansas River Navigation System
A Geographic Information System (GIS) was used to assist the selection of environmentally sensitive dredge material disposal sites along the Arkansas River Navigation System. Maintenance...

Identification of Aquifer Parameters in Confined Groundwater Flow
The logarithm of the aquifer properties, log transmissivity (log T) and log storativity (log S), are regarded as realizations of stochastic processes whose estimates are required. The...

Numerical Model Study of Groundwater Movement in an Aquifer of Bangladesh
Annual groundwater level variation in the aquifer of the Mymensingh-Tangail area of Bangladesh was simulated by applying an implicit finite-difference model of groundwater flow. The groundwater...

Optimization of Freshwater Inflow to Estuaries
This paper presents a methodology that can be used for determining the optimal freshwater inflows into bays and estuaries for the purpose of balancing freshwater demands with the harvest...

The Center for Advanced Decision Support for Water and Environmental Systems
In July of 1988, the US Bureau of Reclamation awarded the University of Colorado a 4 year, 4 million dollar Cooperative Agreement for the development of a Center of Excellence in the Application...

Conductivity and Transit Time Estimates of a Soil Liner
A field-scale soil linear was built to assess the feasibilty of constructing a liner to meet the saturated hydraulic conductivity requirement of the U.S. EPA (i.e., less than 1 ? 10^-7...

Vaporizing VOCs
The authors summarize the findings of a study for the Environmental Protection Agency on vapor extraction of volatile organic compounds from soils. The potential for ground water contamination...

Remediating A Fire Site
Machin and Ehresmann describe remediation of a 15 acre fire site at Fort Huachuca, Ariz. An investigation after the fire showed that all of the debris contained asbestos. Sampling confirmed...

Oilcrete
Threatened by probable tightening of hazardous-waste legislation, oil companies are searching for ways to dispose of or stabilize oil-drilling byproducts. One way is cementitious stabilization...

Regional Traffic Assessment for Major Growth
This paper presents the methodology and findings of a major regional transportation analysis. The results of the study lead to the development of a Transportation Improvement Plan for...

Tri-County Based Travel Demand Forecasting Analyses in the Tampa Bay Area, State of Florida
This paper describes the application of the micro-computer compatible Florida Standard Urban Transportation Modeling Structure (Micro-FSUTMS) to estimate traffic volume for the purpose...

Integrated Transit Network Analysis
As part of an update of the Boston, Massachusetts regional transit simulation process, the Central Transportation Planning Staff (CTPS) has implemented a microcomputer-based integrated...
