Most of the town gets its water supply from this river. Khariar Road is surrounded by some small mountains. These mountains are the part of the Eastern Ghats. The land here has medium range fertility and most of the farmers here prefer to grow rice. Overall it has a well to do topography. But in the season of summer it faces water scarcity as the river gets dried during that time.
