Document Summary
Flow nets are essentially graphic solutions to groundwater flow equations. A groundwater flow system can be represented by a two-dimensional cross-section of the region under study. Then a flow net can be constructed on this two-dimensional area by sketching lines of equal hydraulic head (equipotential lines), and lines that indicate the direction of flow (flowlines). It"s not necessary to have actual data in order to produce a flow net, it can be drawn using the best estimation of the cross-sectional area. The construction (drawing/sketching) of flow nets is something of an art. Flow nets are usually achieved on a trial and error basis, which can be frustrating. But before beginning, take a moment to think the problem through and refer to the guidelines also outlined below. Note that there are no required steps or procedures to drawing a flow net, but the following suggestions should help avoid problems.
