Question 2:
Compare the above system with the probable systems in hilly/mountainous
areas or plains or plateau regions.
Answer:
In plains, the water harvesting structures are crescent-shaped earthen
embankments. These are low, straight, and concrete.
In hilly regions, the system of canal irrigation called Kulhs is used for water
harvesting.
This involves a collection of rain water in a stream, which is then diverted into
manmade channels down the hill sides.
