On the one hand, a sensitivity analysis has been performed to derive relevant structure and failure related parameters. Furthermore, numerical simulations have been set up to assess the inundation propagation within real project areas along the German Baltic Sea coast. The sensitivity analyses include investigations for derivation of dependencies between structure related, respectively, failure related parameters and parameters necessary for damage and risk assessment. The influence of the breach width, breach location, failure duration, return period of the storm surge, storm surge fullness and the influence of tides on the inundation propagation have been investigated. As a result, the breach width, return period of the storm surge and the storm surge fullness are the decisive parameters. The combination of the storm tide and the subsequent tide are relevant for the determination of the maximum inundation depth in tidal influenced coastal areas. Numerical simulation for the area of Markgrafenheide confirmed the results of the sensitivity analyses. Moreover, the topography of the protected area exerts the most striking influence on the inundation propagation. Additionally, comparative analyses between the phjsical-anafytically approach by Führböter (1987) and the numerical model Mike 21 have been performed.de0452-77392017143181MarkgrafenheideMike 21Numerical inundation modelling sensitivity analysisJournal ArticleOther
