Detailed explanation-1: -(a) Surface Irrigation: Just flooding water. About 90% of the irrigated areas in the world are by this method.

Detailed explanation-2: -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-3: -Surface irrigation has evolved into an extensive array of configurations which can be broadly classified as: (1) basin irrigation; (2) border irrigation; (3) furrow irrigation; and (4) uncontrolled flooding.

Detailed explanation-4: -Methods of Irrigation. 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.
