Analytical equations and methods for aquifer test analysis
Unsteadystate flow equations 1. Superposition principle: 2. Green’s function: 3. Green’s function (from leaky aquifer): where
Steadystate flow equations 1. Superposition principle: where 2. Green’s function: where
Methods of analysis and parameters being estimated
Analysis is based either on superposition principle or on Green’s function. 1) by drawdown values at steadystate (the transmissivity value calculated using Green’s function would be twice lower); 2) the graph is plotted only for the equation based on superposition principle.

Methods of analysis and parameters being estimated
Analysis is based either on superposition principle or on Green’s function. Green’s function being applied, the number of terms in the series should be increased. 1) use final recovery data for straight line (the transmissivity value calculated using Green’s function would be twice lower); 2) the graph is plotted only for the equation based on superposition principle.
