Question

Quizplus · Accepted Answer

In humid regions, the highest discharge occurs towards the downstream end of the river basin because the water has collected water from various tributaries and streams along its path downstream. As the river progresses downstream, it collects more and more water and therefore has a higher discharge than the upstream portion of the same river.
