Right answer is (a) strengthening of canal banks

Easiest explanation: Internal silting method is adopted only when new canals are constructed as the section has to be sufficiently wide. In the external silting method, subsidiary banks are constructed to hold the water externally in a confined position. Both of these are methods of strengthening of canal banks.

Calculate the effective unit tractive force that causes bed load transportation if the unit tractive force produced by the flowing water is 3.20 N/m^2. The Manning’s coefficient on an unrippled bed is 0.0108 and the actual observed value of Manning’s coefficient on ripped channels is 0.0222. Take the value of critical shear stress that is required to move the grain particle as 0.5 N/m^2.
