Models for Estimating Core-Cycle Rate of Penetration at Yucca Mountain, Nevada

Preparation of Notification Models Using Continuous Modeling Techniques
Public health departments in many states now require that operators of collection systems notify them of discharges from combined sewer systems soon after these events occur. This allows...

COASTMAP: An Integrated System for Environmental Monitoring, Modeling and Management
The development of COASTMAP, an integrated system for environmental monitoring, modeling and management for fresh and marine waters, is presented. The system allows the user to collect,...

Detailed Measurements of Scour at Bridges
The U.S. Geological Survey, in cooperation with the Federal Highway Administration, has recently developed equipment and techniques for collecting detailed bathymetric and hydraulic data...

Computational Tools for Subsurface Conceptualization
Development of subsurface conceptual models for use in groundwater flow and transport modeling requires that existing data in the form of boring logs, cone penetrometer (CPT) logs, geophysical...

Effects of Spatial Data Resolution and Subarea Size on a Distributed Runoff Model
Spatial data layers of elevation, land use, and soils for a small agricultural watershed in Pennsylvania were used to study the effect of resolution degradation of raster data on the output...

Hydrodynamic Changes Associated with Navigation Traffic on the Upper Mississippi River System
Research has been conducted at the Illinois State Water Survey for the last five to seven years to collect field data from the Illinois and Mississippi Rivers to determine the extent and...

Distributions of Return Flow in Navigable Waterways
Physical impacts of barge traffic on the riverine environment have drawn increasing attention from resource managers of the Upper Mississippi River System (UMRS). Return flow, which can...

Spatial Statistics for Rainfall Forecasts Assessment
Assessments of rainfall forecasts were developed using GIS-based spatial statistical procedures applied to calibrated radar-rainfall fields in central Oklahoma. The overall objective of...

Status Report — Task Committee on GIS Models and Distributed Models of the Watershed
In recognition of the trend toward the adoption of geographic information system (GIS) technology in analyzing hydrologic problems and the obvious applications of GIS in incorporating...

Water Use Recession in San Diego Region
Water use in the San Diego region was studied using historical records collected over a period of a half century. The results indicated that the water use in this region was historically...

Measurements of Bridge-Scour Depths in Mississippi
This paper briefly summarizes 190 measured pier-scour depths collected dur ing 1942–94 at 22 selected bridges in Mississippi and presents an envelope-curve equation for the data. The envelope-curve...

Development of a Hydrologic Model with Both Spatially Distributed and Physically Based Capabilities
A distributed hydrologic model is developed at The Pennsylvania State University for use with rasterized data bases. The purpose of the Terrestrial Hydrologic Model or THM is to investigate...

Use of Geomorphic Data for Assessing Stream Stability at Bridge Structures
The authors recently completed a statewide bridge scour evaluation for the Nevada Department of Transportation, which included evaluation of the geomorphic processes of bank erosion and...

Urbanization and Hydrologic Consequences in Simi Valley, California
Regressional analysis of historical hydrological data including rainfall and runoff data reveal that although there has not been a significant temporal change in the amount of rainfall...

County-Wide Drainage Study Using GIS
A county-wide drainage study was conducted for the County of San Joaquin, California, Department of Public Works, for the determination of storm runoff quantities for the planning of flood...

GIS Applications in Modern Stormwater Management
A Geographic Information System (GIS) is a technology that aids stormwater management through efficient data manipulation, analyses, and graphic displays. The integration of GIS with stormwater...

Direct Measurement of Turbulence Structures in a Standard Jar Test Tank Using PIV System
Particle image velocimetry (PIV) is applied to the measurement of instantaneous two-dimensional velocity fields in a standard 2-liter jar test tank for several different impeller speeds....

Data Analysis for Computer Modeling of Thermal Discharges
Assessment of the thermal discharge impact upon the environment and design of the appropriate discharge structure necessitate a range of data activities, from extensive field measurements,...
