A river terrace is composed of an abandoned surface, or tread, and the incised surface, or riser. [2] If you can date the age of the terrace tread, one can get an estimate of the age of abandonment of that surface, and the age of incision. A simple calculation of h 1 /t 1 can give the average rate of incision(r i), where h i = height of river ...

The river at left has encountered a formation of erosion-resistant volcanic breccia, causing it to downcut more rapidly on the right, leaving terraces of different elevations. Paired and unpaired terraces: Terraces of the same elevation on opposite sides of either a stream or river are called paired terraces. They occur when it downcuts evenly ...

Sediments underlying fluvial terrace exposed in cutbanks along the Manú River, Peru. In geology, a terrace is a step-like landform. A terrace consists of a flat or gently sloping geomorphic surface, called a tread, that is typically bounded on one side by a steeper ascending slope, which is called a "riser" or "scarp".
A bend or curve in a coastline, river, or other geographical feature typically indicating an especially large, open bay that is shallower than a sound. billabong In Australia, a branch of a river that is cut off when the main stem changes course, leaving an elongated and often ephemeral waterhole or oxbow lake.

Earth scientists called such benches "structural benches." Second, other benches are narrow fluvial terraces created by the abandonment of a floodplain by a river or stream and entrenchment of the river valley into it. Finally, a bench is also the name of a narrow flat area often seen at the base of a sea cliff created by waves or other ...
