Analytical equations and methods for aquifer test analysis
Unsteadystate flow equations 1. Superposition principle: 2. Green’s function: 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 the superposition principle or on Green’s function. 1) use 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 the superposition principle or on Green’s function. 1) use initial recovery data for straight line (the transmissivity value calculated using Green’s function would be twice lower). Applying superposition principle gives: Applying Green’s function gives:
