Analytical equations and methods for aquifer test analysis
Unsteadystate flow equations Constant water level in adjacent aquifer Drawdown in the main aquifer where Drawdown in aquitard Drawdown in aquitard (slightly leakage) or approximation (late time) where zp – distance from observation point to top (or bottom) main aquifer, m.
Alternating water level in adjacent aquifer Drawdown in the main aquifer (1) Drawdown in adjacent aquifer (2) Drawdown in aquitard where
Drawdown in semiinfinite aquitard where Drawdown in semiinfinite aquitard (slightly leakage) or approximation (late time)
Methods of analysis and parameters being estimated
Aquifer parameters estimation can be made both from drawdowns in the main and adjacent aquifers. For constant water level in adjacent aquifer For drawdown in semiinfinite aquitard Drawdown in semiinfinite aquitard (slightly leakage) For approximation
