When a river is forced into several channels, seperated by islands made by deposited sediment, during the summer months, the glaciers melt a lot so increase the river discharge, more sediment transported & when the temp drops the glaciers freeze
1 of 5
Deltas
triangular shaped depositional lanform at the mouth of a river where the river energy is absorbed by the sea and cause deposition on the bed creating braided channels. formed when the rate of depos. exceeds rate of removal
2 of 5
Meanders
caused by erosion and deposition will eventually form an oxbow lake, Helicoidal flow,
3 of 5
Waterfalls
fluvial erosion, large drop creating a gorg. hard rock becomes undercut collpases plunge pool created
4 of 5
Potholes
Circular hollows or depressions on the channel bed drilled by turbulent high velocity water loaded with pebbles
