When running water erodes rock and soil, it can create landforms such as valleys, canyons, gorges, and river deltas. Valleys and canyons are formed by the gradual erosion of the surrounding landscape, while river deltas are formed when sediment carried by the river is deposited at its mouth. Gorges are narrow valleys with steep sides, often carved out by fast-moving rivers.
V shaped valleys, meanders, oxbow lakes, gorges, waterfalls rapids & deltas are some.
a tunnel, canyon, delta, edit this. i have no more ideas .if you do then erase this
Deserts were not a major economic feature of river valleys. People living in the river valleys relied heavily on agriculture.
Deltas are formed by constructive erosion.
A particularly famous one is the Grand Canyon, however there are many more.

There are many types of deltas: River-dominated deltas - Mississippi. Wave-dominated deltas - Nile. Tide-dominated deltas - Ganges.
