Question

Groynes can be used with other training works depending upon the purpose they are used for.

(a) True

(b) False

I had been asked this question by my school teacher while I was bunking the class.

This is a very interesting question from Control and Training of Rivers topic in section Rivers Behaviour, Control and Training of Irrigation Engineering

Answer 1

Right option is (a) True

The best I can explain: Generally groynes are used for purposes like, protecting the bank, contracting a river channel to improve its depth, silting up the area by creating sack flow, and training the river along a certain course. So, therefore a groyne can be used with other training measures depending upon the purposes.
