Study on Littoral Protection by Sand-Filled Tube
This study focuses on a new, excellent construction method which excels in both the environmental and scenic aspects. It enables the construction of coastal structures such as jetty, detached...

Simulation-Based Training for Transportation Management Center (TMC) Operators
Effective simulation-based training for Transportation Management Center (TMC) operators enables operators to make the best use of their TMC and thereby to improve the efficiency and safety...

Flood Assessment at a Low-Level Radioactive Waste Site in Southern Nevada
Flood hazard analysis on alluvial fans using Federal Emergency Management Agency (FEMA) methodology is not limited to the FEMA Alluvial Fan Methodology (AFM). Other FEMA-accepted methods...

An Integrated Software System for 3DFEMWATER: A 3D Grid Generator, A Graphical Post-Processor, and Additional Analysis Tools
An integrated software system for 3DFEMWATER has been developed to improve the groundwater flow modeling process. The system generates finite-element grids, graphically portrays simulation...

Hydrologic Regionalization Using a Homogeneity Test
A framework is presented for a regionalization method with a region of influence (ROI) approach. The methodology explicitly incorporates a homogeneity test in the process of selecting...

Application of Vadose Zone Flow and Transport Models
This paper summarizes application of two subsurface flow and transport models at Superfund sites, and evaluation of a number of other unsaturated zone models. The screening level models...

Flow and Transport of Nonaqueous Phase Liquids in Groundwater Systems
Nonaqueous phase liquids (NAPLs) are present at numerous hazardous waste sites and are suspected to exist at many more. Due to the numerous variables influencing NAPL transport and fate...

Spatial and Temporal Precipitation Characteristics in Southwest Idaho
The USDA-ARS, Northwest Watershed Research Center operates a precipitation gage network on the Reynolds Creek Experimental Watershed in southwest Idaho. Analysis of the 30-yr (1962-1991)...

Siting Agricultural Weather Stations
Studies were conducted in Arizona and Washington to investigate how the surrounding fetch affects data collected by agricultural weather stations (AWS). AWS surrounded by extensive areas...

Soil Bulk Density Sampling for Neutron Gauge Calibration
The ASCE Task Committee on Neutron Gauge Calibration met in Logan, Utah in July 1992 to investigate the various methods of soil sampling, installation of access tubes, effect of various...

Case Studies of Bridge Scour in Western New York
As part of the New York State Thruway Authority's bridge hydrologic/hydraulic evaluation program, 63 structures over 42 stream crossings in western New York were assessed for scour potential...

Comparison of Theoretical and Historical Scour
As part of scour assessments at approximately 120 stream crossings on the New York State Thruway, subsurface investigations were performed at all structures and, in some instances, locations...

Sediment Disposal and Transport in Central SF Bay
The relocation of dredged material from navigation channels in the Francisco Bay is crucial to the movement of deep-draft shipping and shallow-draft recreational vessels. The margins of...

Gully Intrusion on Reclaimed Disposal Sites
A three-phase gully erosion study was initiated at the Engineering Research Center of Colorado State University, in cooperation with the U.S. Nuclear Regulatory Commission. The objective...

Evaluation of Historical Scour at Selected Stream Crossings in Indiana
Geophysical data were collected by means of ground-penetrating radar and tuned transducer systems to estimate the historical scour at ten bridges in Indiana. These geophysical data were...

Bridge Scour Evaluations in Washington State
Eighteen existing bridges were investigated for Washington State DOT as part of the FHWA National Scour Evaluation Program. Investigations included review of file information, site inspection,...

Shale Scour at BNRR Yellowstone River Bridge, MT
Both the Burlington Northern Railroad and Montana Department of Transportation bridges across the Yellowstone river just south of Laurel, Montana, are founded on spread footings placed...

Issues in GIS-Based Subsurface Data Management
Obstacles and barriers preclude an interagency GIS application for managing spatially-related subsurface data. Such a system would enable geotechnical and earthquake engineers from state...

National Geotechnical Experimentation Sites?Central Data Repository
A central data repository is in the process of development for the recently-established system of U.S. geotechnical experimentation sites. Data which will be available for most of these...

A Geotechnical/Earthquake Engineering Information System?Expanding the GIS Conceptual Framework
Data in a typical geotechnical and earthquake engineering study, encompass a variety of sources of information from site investigations, field instrumentation, dynamic computer simulations,...
