A model was created to study how beaches and dunes change over time due to sand moving along the shore and towards the land. The model was tested using data from Angelholm Beach in Sweden, and it showed that the simulated changes matched well with what was actually observed. This means the model can help us understand how beaches and dunes evolve, even though not all details could be confirmed due to limited data.
