Calculation of volume of earth work as applied to roads and channels
Problem
1. Compute the depth of cut and height of bank at the various section along the given line from the following data.

Solution
Distance between any two adjustment sections is 30 m
Falling gradient is 1 in 50
For every 30 m = 1/50 x 30=0.6
The depth of cut or height of bank is tabulated below.
