Waterfalls and Gorges Key words: Hard rock / soft rock Overhang and undercutting Plunge pool Retreat upstream
Landforms usually found in the middle and lower courses of a river. Meanders point bars and river cliffs Ox bow lakes Floodplains and terraces Braided channels Mudflats and deltas
Meanders Key words Sinuosity Helicoidal flow Thalweg Pools and riffles Cross section of a bend Point bar River cliff Lateral migration Downstrean migration
