INDIAN GEOGRAPHY

Detailed explanation-1: -Probably one of the oldest methods of irrigating fields is surface irrigation (also known as flood or furrow irrigation), where farmers flow water down small trenches running through their crops.

Detailed explanation-2: -In uncontrolled flooding, there is no conditional logic to control how the node distributes information packets to its counterparts. Without these restraints, repeated distribution of the same packet can occur. These are referred to as broadcast storm or ping storm.

Detailed explanation-3: -(e) Furrow method. levees to guide or restrict the flow of water on the field, the method is called ‘uncontrolled’, wild or ‘free’ flooding. In this method of flooding, water is brought to field ditches and then admitted at one end of the field thus letting it flood the entire field without any control.

Detailed explanation-4: -(b) Flood Irrigation: This kind of irrigation is some times called as Inundation irrigation. In this method of irrigation soil is kept submerged and flooded with water, so as to cause thorough saturation of the land. (2) Sub-surface Irrigation: In this type of irrigation, water does not wet the soil surface.

Detailed explanation-5: -Flood irrigation also called inundation irrigation is an irrigation method that intentionally creates a flooded land condition. This makes the soil completely saturated. After this, occasional natural rainfall is sufficient for the maturity of the crops.
