- •
Phases of aggradation/incision in response to climate and tectonic activity during the late Quaternary have been studied.
- •
The oldest aggradational landforms preserved south of the MCT are dated between 32-49 ka.
- •
The period between 10-5 ka suggests lowering of fluvial discharge and sediment transport capacity.
- •
Major phases of bedrock incision have been dated during ~ 49 ka, 32 ka, 16 ka, 12 ka, 8 ka and around 5 ka.
- •
The period between 9 and 5 ka shows relatively enhanced surface uplift (2-5 mm/year).
