Actuarial Modelling Club: „Rain Chaser - Modellierung des Oberflächenwasserabflusses bei Starkregenereignissen“

Lecture

Onnen Siems und Carina Götzen, Meyerthole Siems Kohlruss GmbH

Starkregenereignisse sind häufig lokal stark konzentriert. Zudem hängt der Eintritt eines Schadens von der umliegenden Topographie ab. Rain Chaser ist ein geophysikalisches Modell zur Ermittlung der Starkregengefährdung das Pegelstände unabhängig von Schaden- und Niederschlagshistorien erstellt. Die Auswirkungen von Starkregenereignissen werden erstmals österreichweit auf Basis digitaler Geländemodelle simuliert und an historischen Ereignissen im Versicherungsbestand verprobt - eine Innovation, die sich von den gängigen Starkregenmodellen markant unterscheidet. Während diese auf Pegelhistorien oder statischen Ableitungen der Höhenmodelle beruhen, können die Algorithmen des Rain Chaser transparent und nachvollziehbar die Abflüsse darstellen und erlauben einen neuen Ansatz in der Gefahreneinschätzung.
