Concerning the Coefficient of Storage of Aquifer (2)

Atgtract In the last paper“Concerning the Coefficient of Storage”publised in this idutnitl Vol.14 (1968), the writer advocated a thinking Way of the decreasing of ground-water orage by pumpage aid, as the result, diminishing of coefficient of storage, which teas a kind of measure to evaluate the ground-water storage. But he described also in the paper that his advocation was no more than an idea and did not reach its conclusion.
Through the study thereafter, the writer noticed an inperiection in the thinking way or the treatment of the unit of pumpage periodt. Then he corrected them and discovered an easy graphycal solution, under the condition remaining transmissibility concerned unchangeable.
