PPT-Confined aquifer storage

281 The coefficient of storage of a confined aquifer is found to be 68 x 10 4 as a result of a pumping test The thickness of the aquifer is 50 m and the porosity is 025 Determine the fractions of the expansibility of water and compressibility of the aquifer skeleton in making up the storage coefficient of the aquifer.
