The dam presented below is 180 m long (in the direction perpendicular to the plane of the cross-section). For the water elevations given on the drawing: a) Construct the flow net (minimum number of equipotential lines should be 10), b) Calculate the rate of seepage for the entire dam, c) Find the total uplift force on the dam (ignore barriers), and d) Estimate the hydraulic gradient at points A, B, and D.

Question

The dam presented below is 180 m long (in the direction perpendicular to the plane of the

cross-section). For the water elevations given on the drawing:

a) Construct the flow net (minimum number of equipotential lines should be 10),

b) Calculate the rate of seepage for the entire dam,

c) Find the total uplift force on the dam (ignore barriers), and

d) Estimate the hydraulic gradient at points A, B, and D.

Recommended to use a spreadsheet to include all equations for calculations of potentials.
