Abstract

Tsunamis generated by submarine landslides were analyzed through a linear analytical model. Analytical solution existing in the literature was generalized to include different bottom profiles and maximum run-ups originating from two different bottom forcing functions, namely Gaussian wave and solitary wave cross sections were compared. Results indicated that the Gaussian cross section produces slightly larger maximum run-up than the solitary wave cross section, even if the two profiles had the same maximum vertical thickness initially and the area occupied by the former was less than the latter.

Farklı Taban Profiline Sahip Denizaltı Heyelanları Sonucu Meydana Gelen Tsunami Tırmanması için Analitik Bir Çalışma

Abstract

Denizaltı heyelanlarının meydana getirdiği tsunamiler doğrusal bir analitik model aracılığıyla incelenmiştir. Literatürdeki çözüm farklı taban profillerini içerecek şekilde genelleştirilmiş ve kesiti Gauss ve soliter dalga olan taban profilleri sonucu oluşan maksimum tırmanmalar karşılaştırılmıştır. Sonuçlar, başlangıçta aynı kalınlığa sahip olmalarına ve Gauss profilinin kapladığı alanın daha az olmasına rağmen bu profilin oluşturduğu maksimum tırmanmanın daha fazla olduğunu göstermiştir.
