An Innovative Cask for Transporting Defense High-Level Waste
In the early 1980s, the U.S. Department of Energy/Defense Programs (DOE/DP) initiated a project to develop a safe and efficient transportation system for defense high-level waste (DHLW)....
Three-Dimensional Plume Dynamics in the Vadose Zone: PORFLO-3 Modeling of a Defense Waste Leak at Hanford
In 1973, approximately 450 m3 of liquid containing radioactive and chemical wastes leaked from the 241-T-106 single-shell tank into the vadose zone...
An Overview of the Vitrification of Defense High-Level Waste at the Hanford Site
Nearly 63 percent of the nation's high-level nuclear waste has accumulated at the U.S. Department of Energy's (DOE) Hanford Site in Washington State. This accumulation...
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...
Validation of a Traffic Modeling System for Detour Planning
The Downtown Seattle Transit Project (DSTP) was initiated as an effort to relieve existing traffic congestion in downtown Seattle. It consists primarily of a 1.3-mile electric-bus tunnel...
Using GIS Techniques for Transportation Planning to Automate Compilation of Land Use Information
This paper describes a procedure used to compile land use or socioeconomic data for traffic analysis zones for input into a transportation planning model. The procedure uses a combination...

Predicting Overland Flow Response: Effects of Spatially-Varying Soil Properties
A physically-based model of Horton overland flow is applied to experimental data from a simulated rainfall event in eastern Washington. The model employs the Green-Ampt infiltration equation...
Intergovernmental Agreements in Watershed Planning
Management of the surface water system not only rests with state and federal agencies, but more importantly, with local jurisdictions. Recognizing this, a cooperative effort was undertaken...
