Summary

Groundwater is an extremely important and sensitive asset. This paper deals with the issue of groundwater recovery through water pumping projects and in particular through water wells.Basic hydraulic definitions and parameters are presented, which are decisive for determining the quantity and quality of available groundwater in an area.Subsequently, various water pumping projects are examined. The construction of these projects is described and the criteria for selecting the appropriate drilling method for achieving effective water well drilling are listed.Subsequently, the flow of groundwater to the well is analyzed and analytical relationships and considerations are reported. The movement of groundwater towards a well in an unconfined aquifer is studied and the simulation of flow using the SEEP/W software under steady flow conditions is presented.The simulation results are compared with the equations of Dupuit and Thiem, and various scenarios are examined (parametric analysis), in order to find those technical and hydrogeological characteristics that most affect the performance of a pumping water well.
