Short summary

We used a 2-D thermomechanical code to simulate the evolution of an orogen. Our aim was to study the interaction between tectonic and surface processes in orogenic forelands. We found that an increase in the sediment input to the foreland results in prolonged activity of the active frontal thrust. Such a scenario could occur naturally as a result of increasing relief in the orogenic hinterland or a change in climatic conditions. We compare our results with observations from the Alps.
