Short summary
The Ebro Delta in Spain has a distinctive coastline shape, the origin of which has been debated. Here we show with two simple models, one of the Ebro River and one of its delta, that is it possible to reproduce this distinctive shape under constant sediment supply, wave climate, and sea-level conditions. We also find that the majority of the delta grew in the last 2000 years, when a great increase in sediment supply from the Ebro River allowed it to accelerate its growth.
