“…The field measurements from the 1993 tsunami along with high-quality bathymetric and topographic data eventually became a benchmark for validating numerical codes. For the record, the numerical model developed by Titov & Synolakis [48,51] now known as MOST was able to successfully model the extreme run-up value of 33 m at a river gully near the town of Monai [52].…”

“…Beyond the development of benchmarked computational codes such as MOST [48,51] which solve the shallow water wave equations, an approximation of the Navier-Stokes equations of hydrodynamics, in this period numerical simulations to higher order approximations of the equations of motion started being developed. One such was the solution of Euler's equations with the un-approximated dynamic free surface boundary condition [61], a numerical approach now known as fully nonlinear potential flow (FNPF).…”

Tsunamis are high-impact, long-duration disasters that in most cases allow for only minutes of warning before impact. Since the 2004 Boxing Day tsunami, there have been significant advancements in warning methodology, pre-disaster preparedness and basic understanding of related phenomena. Yet, the trail of destruction of the 2011 Japan tsunami, broadcast live to a stunned world audience, underscored the difficulties of implementing advances in applied hazard mitigation. We describe state of the art methodologies, standards for warnings and summarize recent advances in basic understanding, and identify cross-disciplinary challenges. The stage is set to bridge science, engineering and society to help build up coastal resilience and reduce losses.

“…In addition to recording free surface elevation at a half dozen locations, maximum wave runup around the entire island was measured. This data set has been used by several researchers to validate numerical runup models (e.g., Liu et al, 1995;Titov and Synolakis, 1998;Chen et al, 2000). In this paper, free surface elevation is compared at the locations shown in Fig.…”

In this paper, a moving boundary technique is developed to investigate wave runup and rundown with depth-integrated equations. Highly nonlinear and weakly dispersive equations are solved using a high-order finite difference scheme. An eddy viscosity model is adopted for wave breaking so as to investigate breaking wave runup. The moving boundary technique utilizes linear extrapolation through the wet -dry boundary and into the dry region. Nonbreaking and breaking solitary wave runup is accurately predicted by the proposed model, yielding a validation of both the wave breaking parameterization and the moving boundary technique. Two-dimensional wave runup in a parabolic basin and around a conical island is investigated, and agreement with published data is excellent. Finally, the propagation and runup of a solitary wave in a trapezoidal channel is examined. D

“…More recent versions of the tool facilitate access to the information through an interactive Web interface [81]. The underlying hydrodynamic model used in ComMIT is MOST (Method of Splitting Tsunami) [82], a nonlinear shallow water model. Lynett et al [44] have shown that MOST, at high digital elevation model resolution (approx.…”

Tsunami-induced currents present an obvious hazard to maritime activities and ports in particular. The historical record is replete with accounts from ship captains and harbour masters describing their fateful encounters with currents and surges caused by these destructive waves. Despite the well-known hazard, only since the trans-oceanic tsunamis of the early twenty-first century (2004, 2010 and 2011) have coastal and port engineering practitioners begun to develop port-specific warning and response products that accurately assess the effects of tsunami-induced currents in addition to overland flooding and inundation. The hazard from strong currents induced by far-field tsunami remains an underappreciated risk in the port and maritime community. In this paper, we will discuss the history of tsunami current observations in ports, look into the current state of the art in port tsunami hazard assessment and discuss future research trends.
