1. Determine the storage coefficient
Problem
A confined aquifer is 25 m thick. 14 x 103 m3 of water is produced over a 2 km2 area by pumping from wells that lower the piezometric surface by 8 m.
Determine the storage coefficient
A B C
D E
Determine the specific storage (in m-1)
Determine the fraction of this yield attributable to compressibility of the aquifer skeleton if the porosity is 0.3
A 0-20% B 20-40% C 40-60%
D % E %
