Simulation of tsunami generation, propagation and coastal inundation in the Eastern Mediterranean

Abstract

Abstract. In the present work, an advanced tsunami generation, propagation and coastal inundation 2-DH model (i.e. 2-D Horizontal model) based on the higher-order Boussinesq equations -developed by the authors -is applied to simulate representative earthquake-induced tsunami scenarios in the Eastern Mediterranean. Two areas of interest were selected after evaluating tsunamigenic zones and possible sources in the region: one at the southwest of the island of Crete in Greece and one at the east of the island of Sicily in Italy. Model results are presented in the form of extreme water elevation maps, sequences of snapshots of water elevation during the propagation of the tsunamis, and inundation maps of the studied low-lying coastal areas. This work marks one of the first successful applications of a fully nonlinear model for the 2-DH simulation of tsunami-induced coastal inundation; acquired results are indicative of the model's capabilities, as well of how areas in the Eastern Mediterranean would be affected by eventual larger events.

Statistical Deviations in Shoreline Detection Obtained with Direct and Remote Observations

“…In Equation 2, the correction be cs may be applied to the distance-dependent error aD as the intertidal beach slope increases, which is in agreement with the inverse proportionality of the normal error with the beach slope [36]. Substituting Equation (2) into Equation 1 and if the longitudinal and transverse errors are grouped, this yields:…”

“…Coastal areas are highly dynamic environments that provide important benefits, but are also subject to a variety of natural hazards such as beach erosion, tsunamis [1,2], and floods [3]. For coastal zone monitoring and coastal risk assessment [4], shoreline detection is a fundamental work.…”

Near- and far-field tsunami waves, displaced water volume, potential energy and velocity flow rates by a stochastic submarine earthquake source model

“…Jamin et al (2015) computed theoretically the kinetic energy and the free surface elevation by an underwater moving bottom using the linear water wave theory and showed that the theoretical results displayed very good agreement with the experimental data. Nonlinear effects become significant and dominant as tsunami enters the run-up phase, see (Lynett and Liu 2002;Glimsdal et al 2007;Løvholt et al 2012;Samaras et al 2015). 45 We applied the transform methods (Laplace in time and Fourier in space) to solve analytical the linearized problem of the long traveling free surface elevation, η, in the open ocean during the generation and propagation processes for constant water depth, h at resonance state (when, v = v t = √gh , i.e.…”

Preface: Oceanographic processes on the continental shelf: observations and modeling

“…Bricheno et al (2014) show the importance of resolving the appropriate spatial scales and using suitable metrics to compare models and data in the nearshore zone. McKiver et al (2016, this special issue) compare the ability of a finitedifference (SHYFEM, shallow water hydrodynamic finiteelement model) and a finite-element model (MITgcm, Massachusetts Institute of Technology general circulation model, Sannino et al, 2014) to simulate coastal processes in the northern Adriatic Sea. The study focused on the northern Adriatic Sea during a severe event that occurred at the beginning of 2012, and gave the opportunity to understand how these events (related to dense water formation) may affect coastal processes, like upwelling and downwelling, and how they interact with estuarine dynamics.…”
