Methods of determining parameters of a confined aquifer with pumping tests

It is necessary to determine parameters of aquifers in evaluation of groundwater resources and calculation of recoverable groundwater withdrawal.Based on pumping tests conducted at two wellfields in northern Shandong province,the possibility of determination of aquifer parameters with pumping tests under a constant pumping rate is discussed in this paper.The method of determination of hydrogeological parameters with pumping tests of constant drawdown is also examined.
