A rill channel is observed at two locations during a storm, 20 and 60 m from the top of the hill. The slopes are 5 and 4 percent, the rill widths are 150 and 220 mm, and the hydraulic radii are estimated to be 01 and 0.04 m, respectively. The sediment transport rate is measured and found to be 200 and 800 kg/m-s. The rill erodibility (Kr) is estimated to be 0.004 s/m, critical shear (τc) 2.5 Pa, and transport coefficient (B) 100. Calculate the sediment transport capacity and erosion rate for each position. Show complete solution.
