Answer 2

Answer:

Basin irrigation is one of the oldest methods of irrigating and is widely practiced where rice is irrigated. As explained in Section 6, rice (unlike most crops and most weeds) can grow when the soil is completely saturated. The basin is formed by leveling the area completely and enclosing it with berms, or levees, Figure 10-1. The side berms will run essentially on the contour. If the land is very sloping, the berms become terraces and a large amount of earth must be moved from the upper side to the lower side. On very steep slopes, the basin will be fairly narrow to reduce the amount of leveling required. Drop structures are required to lower water from one level to another.
