Santagata CE 383 GROUNDWATER FLOW SLIDE 2 INTRODUCTION In many cases the flow of water through soil is NOT in one direction, nor is it uniform over the entire area perpendicular to flow. In such cases the groundwater flow is generally calculated using FLOW NETS . The concept of flow net is based on LAPLACES EQUATION OF CONTINUITY. Impermeable layer 2D FLOW: FLOW NETS 2 Prof. M.
