Mesoforms (scale controlled by channel depth) are also ero-sional and depositional. Many of their distinctive A riverbed made of river deposits is the active flood plain and the flood plain above the bank of the river is the inactive flood plain. Alluvial fans are fan-shaped piles of sediment that form where a rapidly flowing mountain stream enters a relatively flat valley. Natural levees are found along the banks of large rivers. endstream Features Caused by Ice Erosion: •U-shaped valleys: when a glacier erodes a river valley from its original V-shape to a U-shape •Hanging valleys: smaller glacial valleys that join the deeper main valley –Usually forms a waterfall when the ice goes away stream Erosional & depositional glacial landforms 1. 0000001260 00000 n Thus, depositional features are dominant here. <<78B8E866C767F4428B2EB9C1622BD790>]>> z���Zr�� <> 0 The source of a river may lie in a mountainous region and the mouth may meet the sea or lake.

Cliffs, Terraces, Caves, Stacks and Stumps Coarser materials are dropped first and finer silt is carried down towards the mouth of the river; This depositional process leads to the formation of various depositional landforms through fluvial action such as Delta, Levees and Flood Plain etc. 10 0 obj Observe the photographs given below. endstream endobj 253 0 obj<>/Size 234/Type/XRef>>stream Depositional Features and Landforms.

Further on, where they enter larger water bodies, such as the ocean, they create what are perhaps their most recognized depositional features - deltas. They typically smooth, rather than roughen, pre-existing topography, and thus do not create the striking erosional landforms associated with alpine glaciers. endstream Erosional and Depositional Features of Glacial Meltwater Discharges on the Eastern Canadian Continental Margin @inproceedings{Piper2012ErosionalAD, title={Erosional and Depositional Features of Glacial Meltwater Discharges on the Eastern Canadian Continental Margin}, author={D.
