Provide an account of the various erosional and depositional landforms created by running water.

The landforms formed by running water are called plural landforms. They are formed due to abrasion, attrition and erosion-deposition of matter by running water. Various erosional landforms formed by running water: (1) Waterfalls and cascades - when hard rock remains steady while soft rock in the front is eroded. (2) Rapids - formed by erosion of all surface leaving only an isolated standing dykes structures.

Various depositional landforms: (1) Deltas: Formed by deposition of silt at mouth of river. E.g. Sundarbans Delta on Ganga. (2) Spit of sand banks when silt is accumulated inside convex bank of river. (3) Ox-bow lakes: Formed due to cut off and deposition of silt while meandering. E.g. Suga Beel. (4) Floodplains. E.g. Bangar - old Khadar - new alluvial soils with rivers.
