Under recharge boundary conditions, water level in the observation well will drawdown initially under the influence of the production well only. When the cone of depression spreads to the recharge boundary, the time-rate of drawdown will change, due to the influence of the image well. The time-rate of drawdown will thereafter continually decrease till eventually […]
