 Complete the following phrase:  Mader applied his expertise in fluid dynamics to research in the numerical modeling of tsunamis 1974 and other water waves. Using the full Navier-Stokes AMR adaptive mesh refinement Eulerian compressible hydrodynamic computer code called SAGE SAIC Adaptive Grid Eulerian, software developed by SAIC and Los Alamos, he modeled landslide tsunami hazards, such as the 1958 Lituya Bay megatsunami 2002 and the
