Detailed check: (see table below for intermediary results) Probability of flood damage by liquefaction < > Allowable probability of failure => Detailed check passesfails.
Overall check: the Overall result gives a warning because the criteria on "steepest slope over 5 m" is met, an Advanced check is therefore needed.
