AXISYMMETRIC ASCENDING FLOW IN GROUNDWATER PRODUCTION WELL OF MONZOUNGOUDO, BENIN

Abstract

This paper aims to study the axisymmetric ascending flow in a groundwater production well from a captive reservoir of Monzoungoudo. In axisymmetric flow ascending, the pressure is a fundamental hydrodynamic parameter which allows to calculate the behavior of the production water resource. The static pressure of the reservoir and therefore the analysis of groundwater pressure variation through the well are determinate parameters. This study proved that the water pressure decreases from the bottom to the head of the well. The pressure difference (discharge) between the reservoir and the wellhead is the sum of the losses of pressure in the reservoir and the pressure drop in the well.
