Analysis is
based either on superposition principle or on Green’s
function.
1) use
steadystate (the transmissivity value calculated using Green’s
function would be twice lower).
2) for drawdown
only; the graph is plotted only for the equation based on
superposition principle.
Applying
superposition principle gives:
Applying Green’s
function gives:
