Question

what do you mean by basin irrigation​

Answer 1

Answer:

Basin irrigation is one of the oldest methods,of irrigating and is widely practiced where rice is irrigated.As explained,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.The side berms,will run essentially,on the contour.If the land is 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 the other level.
