The question was asked in final exam.

Query is from Navigable Waterways Requirements in portion River Navigation & Tank Irrigation of Irrigation Engineering

Answer 1

Right choice is (c) 2.7 m

The best explanation: The availability of sufficient water depth in the waterway is the chief requirement for navigations and for safe and economical navigation, a minimum depth of 2.7 m is generally required. Lesser depth in the rivers completely eliminates the possibility of towing the ships and causes an increase in the unit cost of transport and a depth of 3.7 m is generally desired in the final development.
