Recent Developments in Stochastic Modeling and Upscaling of Hydrologic Properties in Tuff
A set of detailed geostatistical simulations of porosity has been produced for a layered stratigraphic sequence of welded and non-welded volcanic tuffs at Yucca Mountain, Nevada. The simulations...

Stochastic Simulation of Mass Transport in Heterogeneous Formations Using Hard and Soft Conductivity Data
The mass transport in a synthetic 2-D heterogeneous formation is simulated through the Monte-Carlo method using continuum approach. The simulated hydraulic conductivity field are generated...

Groundwater Flow Modelling for the TVO-92 Safety Analysis of Spent Fuel Disposal
The TVO-92 safety analysis of spent fuel disposal is based on preliminary site investigations carried out at five sites in Finland between 1987 and 1992. Groundwater flow analyses have...

Structure of Crater Flat and Yucca Mountain, Southeastern Nevada, as Inferred from Gravity Data
Existing gravity data in the vicinity of Yucca Mountain and Crater Flat have been examined to determine if these data support only the caldera model or if they support other geologic models...

Detachment Faults?Regulatory Implications for the Yucca Mountain Site
Site characterization investigations at the Yucca Mountain site, Nye County, Nevada consist of a combination of scientific data collection and analyses, and compliance with regulatory...

Geophycal Investigations of Buried Volcanic Centers Near Yucca Mountain, Southwest Nevada
Several aeromagnetic dipolar anomalies occur over flat, alluvial areas near Yucca Mountain that resemble anomalies typically associated with subaerial basaltic volcanic centers. Detailed...

Tourist Visitation Impacts of the Accident at Three Mile Island
This paper analyzes tourist impacts of the March 27, 1979, accident at Three Mile Island. A review of the literature, supplemented with recollections from Pennsylvanian public officials,...

Ambient Air Monitoring to Support HLW Repository Site Characterization
This paper is a description of the program that has been operating in support of the Yucca Mountain site site characterization activities since 1985.The ambient air monitoring is designed...

Functional Analysis: The Path to Effective Training
The regulatory requirements under which the Yucca Mountain Site Characterization Project (YMP) operates mandate that worker proficiency be achieved and maintained. Individuals performing...

Managing Snake River Operations for Juvenile Salmon Migration
A simulation model of Snake River hydrology and water management institutions has been developed. The model was used to investigate management changes to enhance flow conditions for migrating...

Hydro Models and Salmon Recovery in the Northwest
Hydro regulation models provide extensive support for analyzing the efficacy of salmon recovery plans in the Northwest. Power planners developed these computer programs to help plan and...

Snake Reservoir Drawdown ? A Brief Progress Report
The Northwest Power Planning Council has directed the region to employ the use of 'Drawdown' as tool to help threatened and endangered salmon stocks in Snake and Columbia rivers unless...

City of Federal Way Panther Lake Surface Water Study?A Case Study of HSPF Modelling in Urban Detention Basins
This paper presents a case study of using Hydrologic Simulation Program-Fortran (HSPF) as a tool for sizing large urban detention facilities. The Panther Lake drainage basin is a textbook...

Computerized Data Processing and Geographic Information Systems Applications for Development of a 3-Dimensional Groundwater Flow Model
A 3-dimensional numerical groundwater flow model was developed for a 100 square mile area located in the Santa Clara Valley, California. The model development relied upon data base and...

Hydrologic Forecasting?What are the Issues?
The paper briefly describes hydrologic forecasting techniques that are being used today and raises issues that should be addressed as new hydrologic forecast systems are developed and...

Real-Time Water-Control System for the Trinity River, Texas
To provide information for improved flood prevention and control in the Trinity river basin in Texas, we developed a real-time water-control system that (1) retrieves rainfall and streamflow...

Hydrologic Analysis of Leveed Interior Areas
Flood damage reduction projects that include levees or flood walls usually involve special problems associated with isolated interior areas. Storm runoff patterns may be altered and remedial...

A Derived Flood Frequency Distribution for Ungaged Catchments
Flood frequency distribution for ungaged catchments are described in the article. The various parameters that effect the flood frequency distribution are describes. Influence of the climate...

The Impact of Global Warming on Water Resources: Overview and Implications for Coastal California
In the past two years, impressive evidence has accumulated that global warming is occurring and is related to the increase in greenhouse gasses. The impact of the warming process on water...

Impacts of El Ni?o in Western Washington
The climatic phenomenon called El Nino is described, and its impact on hydrologic conditions in western Washington is shown for two recent events. Impacts on water management during the...
