Pumping test analysis using a layered cylindrical grid numerical model in a complex, heterogeneous chalk aquifer

► Pumping test conducted in a quarried Chalk aquifer is analysed numerically. ► Numerical analysis allowed the inclusion of many of the flow processes. ► Simulations did not show the impact of quarries unless they are absent. ► Numerical analysis allowed the estimation hydraulic parameter values. ► Numerical model is a powerful tool to test conceptual ideas.
