Bathymetry CorrectionΒΆ

Large bathymetric slopes may induce computational errors in Boussinesq models. They can even cause numerical instabilities for a case with bathymetry containing a large amount of big slope points (slope>1.0). In that case, you should smoothen the bathymetry or use the following option in input.txt

BATHY_CORRECTION = T

SmoothBelowDepth = –1.0 (for example)

SlopeCap = 1.0 (for example)

SmoothBelowDepth = –1.0 means that the smoothening process will perform from –1.0 m (1.0 m above the still water level) to the sea bed (figure below).

SlopeCape = 1.0 means that the smoothening process will perform around the points where slope > 1.0.
