hydromt_sfincs.workflows.adjust_curve_number(da_cn: DataArray, antecedent_moisture: str | None = 'avg') → DataArray[source]#

Adjust CN-II values to a requested antecedent moisture condition.

Average-condition values are returned unchanged. Dry and wet values are converted using the standard empirical CN relationships and clipped to [0, 100].

Parameters:

da_cn (xr.DataArray) – Curve-number raster for average antecedent moisture.
antecedent_moisture ({"avg", "dry", "wet"} or None, optional) – Target condition, by default "avg".

Returns:

Curve numbers adjusted to the requested condition.

Return type:

xr.DataArray
