AB Erosion rates in the Guadix-Baza basin have been calculated drawing on a volumetric estimation of sedimentloss by river erosion since the late Pleistocene. On this purpose we have perform a reconstruction of thegeometrical surface dated in 43 Ka and defined by a calcrete layer that capes the basin infilling. By comparingthe reconstructed geomorphic surface and the present day topography we have calculated the volume ofsediment lost by hidric erosion in the entire basin. The resulting erosion rate is 6.57 m3ha-1yr-1. Individualerosion rates for Guadix and Baza sub-basins (11.80 m3ha-1yr-1and 1.77 m3ha-1yr-1 respectively) suggest differentstages of drainage pattern evolution in both sub-basins. We attribute the lower values obtained in the Bazasub-basin as related to the downthrowing of this sub-basin due to very recent activity along the Baza fault
