海底滑坡和局部海啸波（希腊科林斯湾）
Submarine landslides and local tsunami waves (Corinthos Gulf, Greece)
摘要：
考虑了海底沉积物滑动产生的水面波浪问题。为了数值模拟滑坡运动，采用了允许考虑滑体组分详细流变特性的方法。基于非线性浅水方程组，对滑坡诱发的表面波进行了数值模拟。研究了两种最大摩擦角下的滑坡性状。详细比较了滑坡动力学和滑坡诱发的地表水波在滑动过程中的演化。研究了泥沙滑动初期产生的偶极水波的演化规律。结果表明，该偶极波可转化为两个波群：波峰和波谷向海方向传播，波谷伴随波峰向海岸线传播。第二个波群首先导致海滩的海水后退，然后才导致大的爬高（具有第一个负相位的海啸波）。
英文摘要：
The problem of submarine sediment slide which generates the surface water waves is considered. To simulate numerically the landslide motion it is used the method which permits to take into account detailed rheological properties of slide body constituents. The numerical simulation of landslide-induced surface water waves is performed on the basis of nonlinear shallow water equations. It is studied a landslide behavior for two values of maximal friction angle. The detailed comparison of landslide dynamics and evolution of landslide-induced surface water waves during sliding is performed. Also, the evolution of dipolar water wave generated in the beginning of sediment sliding is studied. It is obtained that this dipolar wave is then transformed in two wave groups: crest and trough coming seaward and trough accompanied by crest coming to the shoreline. The second wave group leads firstly to sea recession from the beach and only then to large runup (tsunami wave with first negative phase).
