Short summary
The Lannemezan megafan (northern Pyrenean foreland) was abandoned during the Quaternary and subsequently incised. We use numerical models to explore possible scenarios for the evolution of this megafan. We show that autogenic processes are sufficient to explain its evolution. Climate may have played a second-order role; in contrast base-level change, tectonic activity and flexural isostatic rebound do not appear to have influenced its evolution.
