TsunAWI was developed in the framework of the German-Indonesian Tsunami Early Warning System (GITEWS, and simulates all stages of a tsunami from the origin and the propagation in the ocean to the arrival at the coast and the inundation on land. It solves the non-linear shallow water equations on an unstructured finite element grid that allows to change the resolution seamlessly between a coarse grid in the deep ocean and a fine representation of coastal structures.

The implementation started in 2005 and many scientists contributed substantially. TsunAWI was developped by Jörn Behrens, Alexey Androsov, Stephan Braune, Sergey Danilov, Annika Fuchs, Sven Harig, Natalja Rakowsky, Jens Schröter, Dmitry Sein, Dmitry Sidorenko, Olga Startseva, Eifu Taguchi.
