Methods of aquifer test analysis




Visual comparison of measured and calculated drawdowns plots. Drawdowns are calculated either by direct methods (i.e. analytical solutions) or inverse methods, implemented in UCODE and least square method


Straight-line methodvisual comparison of observation data with a straight line calculated for specific conditions, when analytical solutions can be simplified into linear equations. For steady-state solutions, the horizontal line is used


Type-line method – plots of theoretical drawdown in various types of coordinates are manually displaced to match the  observation data in the same coordinates

bisecting line

Method of bisecting line – the ratio between observed drawdowns in the first and second observation wells is compared their theoretical ratio, that is based on the calculated drawdowns


In the column "Method", methods are referred to by short names. The same methods are explained in the relevant sections of the help system.
