The general drawdown equation and its particular cases are considered for a partially penetrating well discharging at a constant rate from an aquifer which is overlain by an aquitard containing the water table. An identity is established between the exact solutions, developed in terms of the ρ = μr / h parameter, and those based on the finite difference approximation, developed in terms of the r / B parameter. The relations in the ρ and the r / B parameter are given for a well of complete penetration. The quasi‐steady drawdown equation is developed for a well of partial penetration in an aquifer‐aquitard flow system. The solution is graphically presented, and its use in the distance‐drawdown curve‐matching procedure is described. Determination of the aquifer‐aquitard formation constants is discussed.
