Collaborative Research: Initial Wave Characteristics from Deformable Submarine Landslides

合作研究:可变形海底滑坡的初波特征

基本信息

项目摘要

Understanding the entire range of coastal hazards is becoming increasingly necessary as populations shift towards nearshore areas. Coastal hazards typically cause flooding and predicting the maximum penetration of the water inland is important in efforts to reduce the coastal destruction and save lives. Flooding from tsunamis generated from earthquakes is far better understood than tsunamis that are generated by submarine ground movements that resemble underwater avalanches. While there have been some attempts to estimate the initial waves caused by submarine slides, predictions vary over a wide range for the same slide conditions, and it is very difficult to meaningfully evaluating the hazard.This research aims at the derivation of empirical formulae that more reliably allow for prediction of initial waves from submarine mass movements. We will use the state-of-the-art hydrocode iSALE which incorporates most essential physical processes to jointly simulate the movement of the slide masses and the generation of the surface waves. The sliding mass is represented as a deformable material and moves freely under the influence of gravity. No external forcing is needed. In this way, not only we can simulate slides that were studied in laboratory experiments, but also able to investigate slides on realistic scales employing realistic geo- materials. We will also develop a graphic tool to allow easy visualization of the landslide motion and the ocean or lake waves that are generated.
随着人口向近岸地区转移,了解沿海灾害的整个范围变得越来越有必要。沿海灾害通常会引起洪水,预测内陆水域的最大渗透程度对于减少沿海破坏和拯救生命非常重要。人们对地震引发的海啸引发的洪水的理解,远远好于对类似水下雪崩的海底地面运动引发的海啸的理解。虽然已经有人尝试估计潜艇滑动引起的初始波浪,但在相同的滑动条件下,预测的范围很大,很难有意义地评估危险。本研究旨在推导经验公式,以便更可靠地预测海底质量运动产生的初始波。我们将使用最先进的hydrocode iSALE,它结合了最基本的物理过程来共同模拟滑动质量的运动和表面波的产生。滑动质量被表示为一种可变形的材料,在重力的影响下自由移动。不需要外力。这样,我们不仅可以模拟在实验室实验中研究的滑动,而且可以用真实的地质材料在真实的尺度上研究滑动。我们还将开发一个图形工具,以方便地可视化滑坡运动和由此产生的海洋或湖泊波浪。
