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.
