Observations on Faults and Associated Permeability Structures in Hydrogeologic Units at the Nevada Test Site

PDF Version Also Available for Download.

Description

Observational data on Nevada Test Site (NTS) faults were gathered from a variety of sources, including surface and tunnel exposures, core samples, geophysical logs, and down-hole cameras. These data show that NTS fault characteristics and fault zone permeability structures are similar to those of faults studied in other regions. Faults at the NTS form complex and heterogeneous fault zones with flow properties that vary in both space and time. Flow property variability within fault zones can be broken down into four major components that allow for the development of a simplified, first approximation model of NTS fault zones. This conceptual ... continued below

This conceptual model can be used as a general guide during development and evaluation of groundwater flow and contaminate transport models at the NTS.
