Analytical equations and methods for aquifer test analysis
Unsteady-state flow equations Profile boundaries: 1. Analysis is based either on superposition principle (for piezometer) 2. Hantush's solution (for piezometer) Laplace transform solution: zp = LTp 3. Hantush's solution (for observation well)) Laplace transform solution: 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. 7. Drawdown in piezometer (pumping well just tapping the aquifer): 8. Mishra's et al. Laplace transform solution for observation well 9. Mishra's et al. Laplace transform solution for piezometer

1) for isotropic aquifer parameters k and a are estimated; 2) for isotropic aquifer either for anisotropic aquifer at z = 0, where 3) for isotropic aquifer; for anisotropic aquifer estimated parameters are |
