A river bank can be divided into three zones: Toe zone, bank zone, and overbank area. The toe zone is the area which is most susceptible to erosion. [2] Because it is located in between the ordinary water level and the low water level, it is strongly affected by currents and erosional events. [2]
The bank consists of the sides of the channel, between which the flow is confined. [1] Stream banks are of particular interest in fluvial geography, which studies the processes associated with rivers and streams and the deposits and landforms created by them. Bankfull discharge is a discharge great enough to fill the channel and overtop the ...
There are two primary mechanisms of stream bank erosion: fluvial erosion and mass failure. Fluvial erosion is the direct removal of soil particles by flowing water. The rate of fluvial erosion is determined both by the force of the flowing water (e.g. faster flow equals more force) and the resistance of the bank material to erosion (e.g. clay is generally more resistant to erosion than sand).
Another example is the restoration of the Isar in Munich from being a fully canalized channel with hard embankments to being wider with naturally sloped banks and vegetation. [29] This has improved wildlife habitat in the Isar, and provided more opportunities for recreation in the river.
The main channel of the Ganges has a bankline of 94 km along its right bank from downstream of Farakka Barrage to Jalangi. Severe erosion occurs all along this bank. From a little above Nimtita , about 20 km downstream from Farakka, the Ganges flows along the international boundary with Bangladesh in the left bank.
Asphalt and sandbag revetment with a geotextile filter. A revetment in stream restoration, river engineering or coastal engineering is a facing of impact-resistant material (such as stone, concrete, sandbags, or wooden piles) applied to a bank or wall in order to absorb the energy of incoming water and protect it from erosion.
A riparian zone or riparian area is the interface between land and a river or stream. [2] In some regions, the terms riparian woodland, riparian forest, riparian buffer zone, riparian corridor, and riparian strip are used to characterize a riparian zone.
