what are the erosional and depositional features of the rivers in the upper ,middle and lower coarse ????

explain briefly with diagrams .

Upper course mostly have erosional features because of high velocity of water.
Erosional features :Waterfall, V shape valley,spurs, gorges,plunge pool

Middle course also forms erosional features because of high velocity of water.
Erosional features:Meanders, oxbow lake
Depositional features:Levees

Lower course mostly form depositional features because of low velocity
Depositional features:Deltas, flood plains, levees, meanders, ox-bow lakes.
