A channel through which water is continually flowing downhill is a stream. A large channel in soil that carries runoff after a rainstorm is a gully.
Runoff is the water flowing downhill across the surface of the Earth.
Deep valleys with cliffs or steep slopes along their sides are called gorges. Gorges are typically formed by the erosion of water flowing through the valley.
A high bank of soil along a river to prevent flooding is called a levee. Levees are built to contain the river within its channel and prevent water from flowing into surrounding areas during periods of high water levels. They help reduce the risk of flooding in adjacent communities.

An excessive amount of water flowing downslope along Earth's surface is called runoff. This typically occurs after excess precipitation or melting snow when the ground is saturated and cannot absorb any more water. Runoff can lead to erosion, flooding, and water pollution.
Sediment that is carried by a stream along the bottom of its channel.
