Strip aquifer: recharge boundaries
Assumptions:
✓general assumptions for bounded (strip) aquifer;
✓image wells form an infinite row, signs of rates shown in figure below;
✓drawdown develops in three stages: unsteady-state, transitional (initial influence of the boundary) and steady-state.
Confined aquifer with parallel recharge boundaries.
a – cross-section; b – plan view.
Fundamental equation:
Laplace transform solution:
This solution is applicable to the following cases:
One well pumped at a constant rate
Pumping
Recovery
drawdown is measured from the beginning of the pumping test
drawdown is measured from the beginning of the recovery test
The whole test period including pumping /injection/ and recovery stages is analyzed
Several wells pumped at a constant rate
Pumping
One well pumped at a variable rate
Pumping
Several wells with time-variable pumping rates
