This is a floodwater harvesting technique called '''controlled flooding''', where the water diverted from a river with the help of diversion structures and canals is spread evenly over a large surface area, known as '''spreading basins''', where it is used for recharging groundwater, irrigation, filling ponds, and watering grazing land. The concept is that a thin sheet of water flows over the land but at minimum velocity in order to avoid disturbing the soil cover. This includes [[Irrigation_-_Spate_irrigation|spate irrigation]], but also standard channel irrigation which takes river water via channels to fields.
