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.
In plains, the water harvesting structures are crescent-shaped earthen embankments.
These are low, straight, and concrete.

Answer :
Water harvesting systems used in hilly/mountainous regions are Naula and Kuhl. Naula is a small well or a pond wherein water is collected by making a stone wall across a stream. This water is used for drinking purposes.
Kuhl are surface channels that divert water from the natural stream and run at high elevation than the streams to irrigate upstream lands.
Darns are also built over hilly mountainous area to store water and later use it for generating electricity.
So, comparing the two systems we can conclude that in plains the harvesting structures are low, straight and concrete earthen embankments whereas in the hilly regions canal irrigation is practiced for water harvesting.
