Abstract

Denizaltı heyelanları sonucu meydana gelen tsunami dalgalarının yayılımlarının modellenmesi için bir analitik çözüm geliştirilmiştir. Önerilen çözüm blok tipi taban profillerinin uygulanmasına imkan verdiği için özellikle deneysel ve sayısal modellerin doğrulanması için kullanılabilecektir. Tsunami tırmanması, yani kıyı çizgisindeki dalga yüksekliğinin zaman serisi ve maksimum tırmanma önerilen analitik model aracılığıyla hesaplanmıştır. Taban profilinin dikliğinin ve uzunluğunun maksimum tırmanma üzerindeki etkileri de ayrıca incelenmiştir.

Keywords

A Benchmark Analytical Solution for Landslide Tsunamis

Abstract

An analytical solution is developed to model propagation of tsunami waves generated by underwater landslides. The proposed solution could particularly be used for validation of experimental and numerical models, since it allows imposition of block-type bottom profiles. Tsunami run-up, that is, time series of water elevations at the initial shoreline, and its maximum is calculated through the proposed analytical model. Effects of steepness of the bottom profile and slide length on the maximum run-up are also analyzed.

Keywords
