The Drainage Basin System

To Start • What main three processes operate to change the shape and profile of a river? • Can you name the types of each process? • CLUE – There are 4 types of 2 of them and only 1 of the other

Which of the following are inputs, processes and outputs?

Tributary (a river which joins a larger river) Watershed (the boundary dividing one drainage basin from another) Confluence (the point at which two rivers join) Catchment (the area from which water drains into a particular drainage basin)
