Download or read book Determination of Rock Mass Permeability written by Timothy W. Zeigler and published by . This book was released on 1976 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: A knowledge of permeability is required to accurately assess and/or predict seepage conditions within a rock mass. This report reviews techniques available for measuring rock mass permeability and provides guidance concerning their application and interpretation. In seepage analyses, the rock mass is commonly modeled as an equivalent porous continuum (i.e. the continuum approach) with seepage governed by the familiar Darcy's law, a linear relationship between flow velocity and hydraulic gradient.
