Chapter 16, Problem 1LC

To determine

To explain: The relationship in stream flow between valleys and interfluves.

Answer to Problem 1LC

In valleys, the drainage systems are well constructed and the water flow follows stream flow; whereas in interfluves, the drainage system is not much good and follows overland flow.

Explanation of Solution

Stream flow:

It is a type of water flow (down-slope movement) where the water flows in channeled movement along a valley bottom.

Valleys:

It is a topographic element on the continent having a well-established drainage system. It consists of valley bottom in partial or total. Valley bottom is the channel that allows a stream of water flow.

Interfluves:

It also a type of topographic element; it is the upland that is located the at the valley walls. Valley walls refer to the land that separates two adjacent valleys. Some of the land comprises of ridge tops and mountain crests and the others are just wide and flat among the drainage systems. Here, the water flows in unchanneled movement.
