Irrigation Engineering
If d1 is the depth of cutting, d2 is the height of the bank from bed level r2 : 1 and r1 : 1 are the slopes in filling and cutting respectively, the horizontal distance n between the bed and bank, is

x = d1 / r1

x = r1 d1

x = r2 d2

x = d2 / r2

x = d1 / r1

x = r1 d1

x = r2 d2

x = d2 / r2
