Applications of Fracture-Flow Modeling to Site Characterization
This paper describes practical applications of discrete-fracture approaches for design and analysis of groundwater flow about high-level radioactive waste repositories. The paper presents...

Fluid Line Deployment and Repair for Space Station
Deployment of the utility system for providing services to the NASA Space Station Freedom provides a unique challenge in design and material technology. The system must be lightweight,...

Conceptual Design for a Lunar-Base CELSS
Future human exploration is key to the United States National Space Policy goal of maintaining a world leadership position in space. In the past, spacecraft life support systems have used...

Upgrading Hydraulic Infrastructure for Level One Redundancy
In the current paper a methodology is presented for upgrading any single source water distribution system in order to provide a level one system redundancy at a minimum cost. A level one...

Soft Bottom Low Flow Channel?A New Approach
In 1987, the City of Boulder, Colorado requested assistance from the Urban Drainage and Flood Control District (District) to repair a problem of cattails growing in the low flow portion...

Utilization of Stormwater Runoff to Recharge Underlying Aquifer
Based on the available data and its proximity to the Capital area, Wadi Al Khawd was selected as the site of the first aquifer recharge project in Oman. The project was designed by Stanley...

Tucson, Arizona's 110-Year Water Resources Plan
The desert community of Tucson, Arizona, has just completed a state-mandated 110-year water supply plan. The plan includes conjunctive use of local groundwater and surface water imported...

Stochastic Optimization of Conjunctive Use in Pakistan
This paper describes an optimization analysis of conjunctive use of ground and surface water that incorporates stochastic inflows and regional variations in groundwater quality and availability....

Groundwater Contamination from an Unlined, Poorly Capped Landfill
This paper presents a case study of groundwater and surface water contamination from a major, unlined, and poorly capped municipal landfill located in Western Washington. The landfill...

Risk Management for Groundwater Contamination: Fuzzy Set Approach
A methodology is developed for health risk management under uncertainty, using fuzzy sets. Groundwater nitrate contamination illustrates the methodology. A risk management framework is...

Using an Index Stream to Make Instream Flow Decisions
The paper discusses development of an Integrated Operating Plan (IOP) that uses an unregulated (natural) stream in the upper Cedar basin as an index of overall hydrologic status of the...

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...

Modeling Groundwater Flow in San Joaquin Valley
Water supply, reallocation and conjunctive use options, within the San Joaquin and Tulare basins of the Central Valley of California, are being considered by Federal and State Planning...

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....

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...

Analysis of Uncertainty in Ground-Water Quality Monitoring Network Design
The paper reviews alternative approaches to ground-water quality monitoring network design. Four general approaches to network design are reviewed: (1) hydrogeologic, (2) simulation, (3)...

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...

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...

Optimization of a Groundwater Well Monitoring Network
An optimization model is presented for the design of a well monitoring network for groundwater quality and quantity parameters. The model utilizes a geostatistical procedure to estimate...
