The aquifer characteristics influencing yield of an artesian well are:
(A) hydraulic conductivity
(B) transmissibility
(C) coefficient of storage
(D) drawdown
(E) circle of influence
Choose the correct answer from the options given below:
Show Hint
For a confined aquifer, the storage coefficient (\( S \)) is very small (\( 10^{-5} \) to \( 10^{-3} \)) because water is released only by the compaction of the aquifer skeleton and expansion of water.
In contrast, unconfined aquifers have a high storage coefficient equal to their specific yield (\( 0.1 \) to \( 0.3 \)).
