Rivers offer : -drain out excess precipitation which helps in preventing flooding and water logging -rivers help in recharge of ground water as the precipitated surplus runoff is carried down by the river system to lakes or/and the sea. Initially, water delivered from the canal was used exclusively by agriculture.
