Swell Inundation System#

title

The Swell Inundation System developed allows to automatically download global wave and level forecast information from GFS database and ESTOFs database respectively, and downscale the information to provide high resolution wave fields, high resolution inundation extents, and its associated impact.

title

For that purpose, and as shown in the sketch above, the system integrates a number of tailor-made metamodels developed for the region, that allow to eficiently downscale the information. The metamodels used are the following:

  • BinWaves: This metamodel, based on a library of prerun cases of monocromatic waves using SWAN third generation model, allows to downscale offshore wave spectra to a local scale at a high resolution (~300m) and obtain the spectral wave parameters to be used by HyBeat

  • HyBeat: This metamodel, based on a library of prerun cases of representative wave conditions using XBeach, allows to obtain the wave SetUp produced at the coast and its associated infragravity wave at a very high resolution (5-20m), which is the input of the flooding metamodel named HyFlood

  • HyFlood: This metamodel, based on a library of prerun cases of representative hyetographs using Lisflood-FP, allows to obtain the flooding maps as the convolution of flooding events every 500m of the coast.
