AbstractIn this work I use the numerical model TAO to study the evolution of the Bureba escarpment, sitting at the watershed between Duero and Ebro Basins and draining into the Rioja Trough. Facies correlation across this area is troublesome through lack of age-dates and therefore timing of tectonosedimentary events is controversial. Numerical modelling should shed some light on the evolution of this area. To that end I have run homogeneous and heterogeneous models for a range of values of erodability, runoff and elastic thickness. The models demonstrate that the tilting of the NE Duero could have resulted from isostatic compensation to erosion in the Rioja Trough and that the Bureba escarpment is a natural barrier to erosion preventing escarpment retreat for at least the next 1 My.
