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