Draw a flow net (following ALL the necessary rules) for the problem described below. Correctly interpreting the problem is part of the challenge. State any assumptions but note that all necessary information for the purpose of the flow net is described in the problem. A levee protects New Orleans from Lake Pontchartrain. The levee is constructed using a 10-m tall concrete 'T-wall' (above the ground surface) and a 20-m deep sheet pile barrier below the ground surface. The sheet pile barrier is positioned below the center of the T-wall (the top of the sheet pile barrier is embedded in the base of the T-wall). The base of the T-wall is 6-m wide. Assume the ground surface on the Lake-side and the City-side of the levee is at the same elevation (same elevation as the base of the T-wall). Draw a flow net that could be used to calculate the seepage beneath the levee. On your drawing, include water on the Lake-side with a depth of 7-m (i.e. - a flood condition), and indicate the best choice for a reference datum. a a
