| Zusammenfassung |
| The assessment of coastal flood risks in a particular
region requires the estimation of typical damages caused by storm
surges of certain characteristics and annualities. Although the damage depends
on a multitude of factors, including flow velocity, duration of
flood, precaution, etc., the relationship between flood events and
the corresponding average damages is usually described by a stage-damage
function, which considers the maximum water level as the only damage
influencing factor. Starting with different (microscale) building damage
functions we elaborate a macroscopic damage function for the entire case
study area Kalundborg (Denmark) on the basis of multiple
coarse-graining methods and assumptions of the hydrological connectivity.
We find that for small events, the macroscopic damage function mostly
depends on the properties of the elevation model, while for large events it
strongly depends on the assumed building damage function. In general,
the damage in the case study increases exponentially up to a certain
level and then less steep. |
