Tsunami Simulation: TsunAWI Testcase "Coquimbo 2015", Setups and Example Results

This dataset contains three setups with example results for TsunAWI simulations for the Chilean coast with a focus on<br> the Coquimbo region. They are used in the LEXIS project, WP6 "Earthquake and Tsunami Pilot". <strong>coquimbo_150m.tgz </strong>- coarse setup with down to 150m resolution in Coquimbo and other areas of interest along the Chilean coast <strong>coquimbo_20m.tgz </strong>- fine<strong> </strong>setup with down to 20m resolution in Coquimbo, also high resolution along other areas of interest along the Chilean coast <strong>coquimbo_20m_new.tgz </strong>- setup tuned for the LEXIS workflow aiming at a real time estimate of the inundation on the City of Coquimbo, thus a focus with 20m resolution only in Coquimbo region. Each dataset includes a README explaining the included files. The following description is taken as pars pro toto from coquimbo_20m_new.tgz. <strong>Computational Mesh</strong> mesh/Coquimbo_20m/nod2D.out <br> Location of mesh vertices in geographical coordinates, vertices on the open boundary are flagged with "1"<br> Resolution in Coquimbo area: 20m mesh/Coquimbo_20m/nodhn.out<br> Water depth at the respective vertices.
