“…Previous analyses of tsunami characteristics have used the shallow-water model with a no-flux boundary condition at a depth of 5-10 m on the shore (Titov and Synolakis, 1998;Sato et al, 2003;Choi et al, 2003;Ioualalen et al, 2007;Schuiling et al, 2007;Zaitsev et al, 2009;Beisel et al, 2009). In this model, runup heights are determined using simplified formulae of the 1-D, analytic theory of long-wave runup for a fixed shape of an incident wave, whether a sine wave or a solitary wave (Choi et al, 2002a;Ward and Asphaug, 2003).…”

Abstract. We propose a method to compute tsunami runup heights that is based on an integration of numerical, 2-D shallow-water modelling and an analytical, 1-D long-wave runup theory. This approach provides a faster forecast of tsunami runup heights than a complicated coastal inundation model. Through simulations of potential tsunami scenarios, this approach can also be applied to long-term tsunami prediction. We tested the model by simulating the historical event in the East (Japan) Sea and found that the estimates of runup heights agreed well with the available observations.

Abstract:Two-dimensional and one-dimensional models are used to evaluate the seashore effects of the tsunami generated by an asteroid hitting the deep water in the Eastern region of the Black Sea. The shallow water theory has been used to describe tsunami propagation. The distance between the impact point and the nearest coast is about 150 km. The effects on the coastal regions depend on many factors among which the most important is asteroid size. The tsunami generated by a 250 m asteroid reaches the nearest dry land location in 20 minutes and needs about two hours to hit all over the Black Sea coast. The horizontal inundation length is also known as run-in or run-off distance, according to the direction of water movement.The run-up values may be up to 39 m in the Eastern basin and a more than ten times smaller in the Western region. The Northern part of the Black Sea coast is not affected by the tsunami. The run-in values of a tsunami generated by a 1000 m diameter asteroid are sensibly larger than the similar values associated to a 250 m diameter asteroid. The run-in strongly depends on the distance from the impact position to the shore and on coastal topographical profile. For instance, the run-in distance in case of a tsunami generated by a 250 m size asteroid is 0.1 km (at Varna), 0.5 km (Ordu), 0.7 km (Yalta) and 1.4 km (Sochi). In case of the 1000 m diameter asteroid the run-in distance is 0.7 km (at Varna) and 2.9 km (Yalta). The results accuracy is also discussed. PACS

“…The comparable analysis of tsunami characteristics was done in early studies using shallow water models with "no-flux" boundary condition on the coast, which was modeled by the equivalent wall in the last sea points usually with depth of 5 to 10 meters (Sato et al 2003;Choi et al 2003;Ioualalen et al 2006;Schuiling et al 2007;Zaitsev et al 2009;Beisel et al 2009). Runup heights were in some cases corrected with use of simplified formulae of the 1D analytic theory of long wave runup for fixed shape of incident wave, sine wave or solitary wave (Choi et al 2002;Ward and Asphaug 2003).…”

: An approach based on the combined use of a 2D shallow water model and analytical 1D long wave run-up theory is proposed which facilitates the forecasting of tsunami run-up heights in a more rapid way, compared with the statistical or empirical run-up ratio method or resorting to complicated coastal inundation models. Its application is advantageous for long-term tsunami predictions based on the modeling of many prognostic tsunami scenarios. The modeling of the Chilean tsunami on February 27, 2010 has been performed, and the estimations of run-up heights are found to be in good agreement with available observations.
