Asked question is from Canal Falls in portion Canal Falls of Irrigation Engineering

Answer 1

Correct answer is (a) command area

The best I can explain: In the case of branch canals and distributary canals, the procedure is to mark the FSL required on the L-section of the canal. It is done so as to cover all the commanded points that decide the suitable locations for fall in canal FSL and in canal beds.
