Source code of the SWAN model: Free Infragravity Waves in the North Sea

This dataset contains the source code of the SWAN model (v41.31, http://swanmodel.sourceforge.net/) extended with an empirical source of free infragravity waves. This modified version of the SWAN model can be used to simulate the evolution of free infragravity waves in coastal/oceanic waters that are radiated from adjacent shorelines. The model can be applied to study the evolution of free infragravity waves at a regional to global scale, ranging from inland seas, marginal seas, to ocean basins. In an accompanying paper (10.1002/essoar.10506505.1), the model was used to understand the spatial and temporal variation of free infragravity waves in the North Sea.
