Watersheds are areas where rainfall falls and is collected by mountain ridges before flowing through smaller rivers and into the main river. Rainfall that falls directly on the ground separates into flow water, evaporation water, and infiltration water that eventually enters the river as stream discharge. Surface runoff can occur from excessive rainwater falling to the ground. Runoff can occur …
