Absolute Permeability Measurement of Water

Abstract

The increase in the use of ground water for municipal, industrial, irrigation, air-conditioning, domestic, and other purposes and the attendant lowering of the water levels in wells have caused much concern regarding the quantity of water that can be withdrawn perennially from subterranean sources. As a result, ground-water hydrologists are persistently confronted with the serious problem of determining the safe yield of underground reservoirs. Such quantitative investigations almost always involve the movement of ground water, and to a large degree the success of these studies depends on a reasonably accurate determination of the quantity of underground percolation. The current research is based on the study of finding the permeability of water. The permeability of water may be, determined by laboratory or field test and also check the Darcy’s law. In the laboratory the permeability may be determined indirectly by analyses of the size, shape, and arrangement of the grains constituting the material, or directly by observations on the rate of percolation of water through samples.
