matching
parameters is the basic technique for aquifer properties estimation
for most conceptual schemes.
The method
consists in solving direct problem of groundwater flow. It allows
to find (match) required coefficients by visual comparing (fitting)
diagnostic drawdown curve with the theoretical graph of the
corresponding analytical equation plotted for given test conditions
(discharge rate, distance to the pumping well, time etc.) and
assumed aquifer parameters. The matching method is an effective and
demonstrative instrument for assessing the sensitivity of applied
conceptual scheme to aquifer and technical parameters, and for
comparing results obtained with application of different conceptual
schemes.
