Figure shows a vertical cross section through a typical concrete gravity dam with a cutoff trench.You are asked to determine the flow of water under the dam and to calculate uplift pressure at thebottom of the dam. The solution to both problems will require that you construct a flow net tosimulate flow beneath this dam.1. Construct a flow net on Figure 1 showing groundwater flow under the dam. 2.
