Answer 1

Explanation:

Bhubaneswar’s storm water flows into these 10 drain channels. But the entire city has not been covered with storm water drains.

This apart, encroachment of natural drains by construction and dumping of waste materials make the storm water drains inefficient, resulting in blockage and chocking. The city’s drain No1 opens to river Kuakhai and the other nine drain channels (No2 toNo10) flow into the Gangua Nallah.

Answer 2

Encroachment on natural drains intensify flooding because these decreases the capacity of drain.

Hope it helps.
