INDIAN GEOGRAPHY

Detailed explanation-1: -Surface irrigation (flood irrigation): It is most common form of irrigation where water is applied and distributed over the soil surface by gravity. Three major types of surface irrigation are level basin, furrow, and border strip.

Detailed explanation-2: -Surface irrigation It is often called flood irrigation when the irrigation results in flooding or near flooding of the cultivated land.

Detailed explanation-3: -BASIN IRRIGATION The bunds prevent the water from flowing to the adjacent fields. Basin irrigation is commonly used for rice grown on flat lands or in terraces on hillsides (see Figure 2a). Trees can also be grown in basins, where one tree is usually located in the middle of a small basin (Figure 2b).

Detailed explanation-4: -In the Zigzag method of flooding, water takes a circuitous route before reaching the dead end of each plot. The whole area is divided into a number of square or rectangular plots; each plot is then subdivided with the help of low bunds or levees. This method is suitable for leveled plots.
