Unsteady-state
flow equations
Profile boundaries:
1.
Analysis is
based either on superposition principle (for
piezometer)
2. Hantush's
solution (for piezometer)
3. Hantush's
solution (for observation well))
4. Moench's
solution (for piezometer and observation well).
5. Moench's
solution (for piezometer and observation well) with
skin-factor.
6. Moench's
solution for pumping well with skin-factor.
