How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Article
Full-text available
While interactions between regular wave driven flooding and reefs have been widely studied due to climate change pressure, the effects of reefs on tsunami flooding have less been investigated. From studies of historical events, reefs can behave as buffers or as amplifiers of inundation, depending upon the location. Interactions between reefs and ts...

Mangroves have an important role in coastal ecosystems providing protection for a wide variety of species. Around the Baja California gulf, the mangrove forests spread along the inner coastline of the gulf but also along the Pacific coast. The aim of this study is to evaluate the dispersion of mangrove tree propagules around the Baja California pen...
Article
Traditionally, the initialization of seismically generated tsunamis is done by setting the initial free surface deformation as identical to the final deformation of the sea floor. However, numerous effects are neglected through this method, in particular the dynamics of the sea floor deformation. Here, two temporal parameters characterizing the sea...
Conference Paper
his paper gives an overview on the capabilities of the TELEMAC-MASCARET suite to simulate different steps of the tsunami phenomenon. The simulation of a full tsunami event includes generation, propagation, shoaling, run up and flooding. To deal with all these steps, a full set of benchmarks were identified with the TANDEM project [1]. Different num...
Article
Full-text available
Tsunami generation have commonly been modeled by using the Okada method (see Okada (1992)), i.e. from seismic data, the final ground deformation is calculated and applied to the free surface as an initial deformation. Using this method, lot of aspects of the generation are neglected, including timescales. The aim of this study is to measure the inf...

This study is part of the joint actions carried out within TANDEM (Tsunamis in northern AtlaNtic: Definition of Effects by Modeling). This French project, mainly dedicated to the appraisal of coastal effects due to tsunami waves on the French coastlines, was initiated after the catastrophic 2011 Tohoku-Oki tsunami. This event, which tragically stru...
Article
A new semi-analytical solution is derived in a linear potential framework for simulating tsunami-like water waves caused by a dynamic sea ground deformation. The movement generating the tsunami is represented by a simplified model of the sea-floor displacement caused by a schematic seismic event. This displacement generalises the earlier work of Ha...
Thesis
Full-text available
The impact of tsunamis on mankind is well known. During recent years, several events showed us the disasters they can trigger which reiterate the importance of understanding their dynamics. Due to the lack of in-situ data, the generation is the least known aspect of tsunamis. As a result, simplified models of the source are used for numerical tsuna...
Conference Paper
Full-text available
This work has been performed by a French national consortium within the framework of the national project Tandem, with aim to improve knowledge about tsunami risk on the French coasts. Workpackage #1 of this project was the opportunity to build a database of benchmark cases to assess the capabilities of 18 codes, solving various set of equations wi...
