Analytical equations and methods for aquifer test analysis

Unsteady-state flow equations Average drawdown in an observation well: Drawdown in a piezometer (full solution): Drawdown in a piezometer (reduced solution):
Steady-state flow equation:
Methods of analysis and parameters being estimated
f – function in square brackets; 1) for isotropic aquifer at steady state; 2) for isotropic aquifer parameters k and a are estimated; 3) for isotropic aquifer the type curve being plotted by average drawdown equation, hydraulic conductivity is calculated as: 4) for isotropic aquifer; for anisotropic aquifer estimated parameters are |
