Q7 ) Find out about the traditional systems of water harvesting/ management in your region.

NCERT Solutions for Class 10 Science Chapter 16 Management Of Natural Resources

In the houses, systems of rainwater harvesting are installed which collect the water running off and channel it into a special pit created for collecting the water.Also soak pits are made to collect run-off water. This helps to recharge ground water.

Q8 ) Compare the above systems with the probable systems in hilly/ mountainous areas or plains or plateau regions.

NCERT Solutions for Class 10 Science Chapter 16 Management Of Natural Resources

Drinking water system in hilly areas:In this system, the water flowing through falls, comes to villages located in lower regions through small human made drains also the water is brought down to the lower areas of hills through bamboo drains.
Drinking water system in plains:small sources are made in various regions like Jhalaras were made in Rajasthan and Gujarat, essentially meant for community use and for religious rites.Also the use of dams is done in many areas.

Drinking water system in plateau regions:Dams or diversion which were built across rivers for the supply of water.In some regions, small pits were dug to collect water.
