Q. How can you design Side Slope of bank?
Angle of bank should be flatter than angle of repose of pitching material. Angle of repose of sand is 2:1 while that of stone is about 1:1. Angle of river bank formed of cohesive soil can however be steeper than 1:1 in which case it is required to be graded and made flatter than 1: 1. Flatter the side slope with respect to angle of repose of pavement material, the size and weight of pitching stone can be reduced.
