Abstract

In order to assess the extent of sediment connectivity between uplands and lowlands and to quantify the processes of in-channel deposition and remobilization, measurements of suspended sediment fluxes were conducted in Cointzio catchment, a nested rural catchment of the Mexican Volcanic Belt. Data were collected over one year at three upland sites. The results show that rather than drainage area, landscape controls were the main drivers of sediment export and surface–subsurface partitioning; widespread rainfall indirectly sustained in-channel erosion; baseflow discharge boosted sediment conveyance in the downstream alluvial plain
