The rates of fluvial incision in South America have varied significantly during the late Cenozoic. These changes are in response to surface uplift of the Andes mountains and climate controlled changes in discharge rates. My research explores the relative importance of these two factors in fluvial erosion of the Andes using paleoclimate simulations and lansdscape evolution models.
