The Best of Both Worlds: Integrating Statistical and Deterministic Approaches to Area Remediation
We seek a complete framework for adaptive area characterization for purposes of remediation, incorporating both statistical and deterministic features. This hybrid methodology involves...

A Comparison of Geostatistically-Based Inverse Techniques for Use in Performance Assessment Analyses at the WIPP Site?Results from Test Case No. 1
The groundwater flow pathway in the Culebra Dolomite aquifer at the Waste Isolation Pilot Plant (WIPP) has been identified as a potentially important pathway for radionuclide migration...

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...

Surface Complexation Model Prediction of Np and Pu Distribution Coefficients
Robust estimates of radionuclide sorption coefficients (K_d) are needed to estimate radionuclide retardation during ground-water transport from a...

Isotopic Evidence of Complex Ground-Water Flow at Yucca Mountain, Nevada, USA
Strontium isotopes (expressed as per mill deviation from mean sea water, ?⁸⁷Sr) reflect interaction between ground water and the aquifer through...

Subsurface Transport of Radioactive Material Using Adaptive Finite Elements
A finite element method which utilizes mesh adaptation is used to calculate transient groundwater flow and pollutant transport. Mass lumping and reduced integration are employed to enhance...

The SECO Suite of Codes for Site Performance Assessment
Modeling for performance assessment of the Waste Isolation Pilot Plant (WIPP) has led to development of the SECO suite of codes for groundwater flow, particle tracking, and transport....

Corrosion Life-Time Assessment of Carbon Steel and Stainless Alloys for Geological Disposal Facility
The disposal facility for radioactive wastes, requires long-term integrity. Metal is considering to use as the engineered barrier which constructs the outer walls in such a facility, in...

Mine Support, Radiation and Ventilation Control with Spray-on Barriers
The use of spray-on liner agents to provide localized excavation support in place of traditional techniques such as shotcrete or bolts-and-screen has been the subject of extensive investigation....

Project on Contaminations-Radiation-Ecosystems-Health in Russia
We would like to discuss with you a project that we are currently developing, doing research upon and completing. In our report we represent the the following: - a few experimental data...

Fresno/Clovis Water Management Plan
The Fresno/Clovis Metropolitan Area (FCMA) in California has historically relied solely on untreated, undisinfected groundwater as a source of potable water to serve 500,000 people. Contamination...

Public Process in Fresno/Clovis Water Supply Plan
Groundwater is the principal reservoir for the Fresno/Clovis Metropolitan Area (FCMA) of Central California. However, significant portions of the aquifer are threatened by pesticides and...

Juanita Creek Channel Restoration?King County, Washington
Juanita Creek, a small basin near Seattle that contains anadromous fish, was experiencing degradation due to urbanization. A detention pond and channel restoration improvements were constructed...

An Isolated Wetland Used for Stormwater Treatment
A marsh used for stormwater management showed gradually increasing levels of pH, dissolved oxygen and conductivity in the flow path. The system was especially effective in removing suspended...

Water Temperature Issues in the 90's and Beyond
Temperature impacts are among the most common and most expensive environmental issues requiring mitigation at water projects. Several emerging environmental and regulatory concerns and...

Sacramento and Trinity River Systems: A Demonstration of River Temperature Management for the 90's
Drought in Northern California resulted in the potential that summer and early fall, 1992, Sacramento and Trinity River temperatures would exceed critical levels for sustaining salmon...

Pollutant Removal Efficiency of Detention Basins
A simple method is presented for quick estimates of pollutant removal efficiency of detention basins under dynamic conditions. The method is based on the generalized solutions to the reservoir...

Long-Term Performance of Wet Detention Ponds
Wet detention is a technology which has been successfully applied in recent years to improve stormwater runoff quality in urban areas. Since most systems have a short operational history,...

GIS Reconstruction of Exposure to Water Supply Contaminants
Groundwater pollution resulting from improper waste handling practices in the aerospace industry contaminated the water supply in Tucson, Arizona. State and federal health officials concluded...

Solute Transport Modeling under Unsteady Flow Regimes: An Application of the Modular Modeling System
Many existing solute transport codes rely on the assumption of steady (i.e. time-invariant) flow. This assumption severely limits such models, as accurate simulations often require realistic...
