A method for determining the storage coefficient of an aquifer using piezometric contour maps is presented which is based on the transient ground-water flow equation simplified and reduced to finite difference form. Since drilling of observation wells is expensive and time consuming, this procedure is particularly useful for preliminary assessment of ground-water resources of an area where no observation wells near the abstraction wells are available. The values of the aquifer storage coefficient in the Pantnagar University Farm area obtained by this method show good agreement with those obtained by means of pumping tests.
