Plateau reduction by drainage divide migration in the Eastern Cordillera of Colombia defined by morphometry and ¹⁰Be terrestrial cosmogenic nuclides

Catchment-wide erosion rates were defined using Be terrestrial cosmogenic nuclides for the Eastern Cordillera of the Colombian Andes to help determine the nature of drainage development and landscape evolution. The Eastern Cordillera, characterized by a smooth axial plateau bordered by steep flanks,...

Descripción
Sumario:Catchment-wide erosion rates were defined using Be terrestrial cosmogenic nuclides for the Eastern Cordillera of the Colombian Andes to help determine the nature of drainage development and landscape evolution. The Eastern Cordillera, characterized by a smooth axial plateau bordered by steep flanks, has a mean erosion rate of 11 ± 1 mm/ka across the plateau and 70 ± 10 mm/ka on its flanks, with local high rates.
