A TVD Lax-Wendroff scheme solves the Boussinesq-type equations is presented, extensively validated, and clearly demonstrated to be a robust and efficient engineering tool to simulate the physical processes involved in the tsunami wave runup and interaction of the propagating solitary waves with the idealized coastal beaches. To better understand the physical processes of the tsunami wave runup at surf zone, a parametric study concerning N-wave runup is carried out. For all cases investigated, the qualitative features of the propagating N-waves remain unaltered, even for the large wave events. The relative maximum runup height and wave steepness are found to be strongly correlated and appeared to be linearly asymptotic in form. Also, the severity of extreme wave attack is found to be a function of beach slope for a given extreme event. The numerical simulations reveal the significance of the nonlinear wave effects on the predicted maximum N-wave runup heights, which provide guidance in selecting the design height of coastal defence structures and specifying the clearance distance between the shoreline and infrastructure.

The 2D laboratory experiments were performed to investigate tsunami wave runup on the combined sand beach. The N-wave was generated in three different water depths. The water surface elevations, maximum elevation of runup and snapshots of wave uprush and back wash were measured. The theoretical analysis of runup was presented. The results showed that uprush water wave had a decelerate process. The maximum elevation of runup R depends on incident wave height H and R is linear relationship with H plus water depth h.

Abstract. Nonlinear transformation and runup of long waves of finite amplitude in a basin of variable depth is analyzed in the framework of 1-D nonlinear shallow-water theory. The basin depth is slowly varied far offshore and joins a plane beach near the shore. A small-amplitude linear sinusoidal incident wave is assumed. The wave dynamics far offshore can be described with the use of asymptotic methods based on two parameters: bottom slope and wave amplitude. An analytical solution allows the calculation of increasing wave height, steepness and spectral amplitudes during wave propagation from the initial wave characteristics and bottom profile. Three special types of bottom profile (beach of constant slope, and convex and concave beach profiles) are considered in detail within this approach. The wave runup on a plane beach is described in the framework of the Carrier-Greenspan approach with initial data, which come from wave deformation in a basin of slowly varying depth. The dependence of the maximum runup height and the condition of a wave breaking are analyzed in relation to wave parameters in deep water.

A simulative analysis methodology is presented and discussed to hindcast the propagation and shallow water transformation of a historical tsunami wave. The initial pulse of water surface induced is numerically modelled based on known geophysical data of earthquake magnitude and seismically induced seabed displacements. The propagation model accounts for the trans-sea movement, long wave propagation and damping, and shallow water transformations but excluding wave runup on the foreshore. The methodology is applied to the Philippine Trench 2012 tsunamigenic event using secondary data from regional geophysical databases and yielded good agreement with observed tsunami heights and arrival times recorded for local and regional locations, particularly at deeper and farther locations from the source.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/SU7IKLh2NDM
