Enquiry is from Techniques of Water Distribution in the Farms topic in division Water Requirements of Crops of Irrigation Engineering

Answer 1

Right answer is (b) Zigzag Flooding

Easiest explanation: In this method, the entire land is divided into square or rectangular plots, which are subdivided with help of low bunds or levees. So, therefore the water which comes from the main ditch takes a circuitous route in each plot to irrigate the land. This is done to control the velocity of the flow of water.
