In hilly regions, rainwater is often collected and channelled with the help of a stream. The stream is diverted to different areas with the help of canals for the purpose of irrigation. In mountainous regions, water is commonly obtained from the rivers that flow from the glaciers.
In the plains, water is obtained from many natural sources such as lakes and rivers. Groundwater is also harvested with the help of bore wells for irrigation and human consumption.Answered by Vishal kumar | 1 year ago
