The Hydro-UQ Application is open-source software that provides researchers a tool to assess the performance of a building subjected to loading due to tsunami and storm surge. The tool allows 2-D shallow water solutions obtained from far-from-coast calculations as input to a 3-D CFD solver. This facilitates a multiscale coupling by resolving areas of interest by coupling shallow-water solvers with CFD solvers through an interchangeable workflow. As a part of the inputs, the tool allows the researchers to consider: (a) bathymetry / topography of the ocean floor (b) initiation conditions due to tsunami / storm surge events. In addition, the tool specifically allows for modeling of experiments from wave flumes (for example, the NHERI Experimental Facility at Oregon State University). The outputs of Hydro-UQ, at present, are the inundation heights and pressures on the building. These simulations are computationally demanding and thus, users have the option to perform the computations on the Stampede2 supercomputer. Stampede2 is located at the Texas Advanced Computing Center and made available to the user through NSF's NHERI DesignSafe, the cyberinfrastructure provider for NHERI.

In upcoming versions, the tool will also facilitate usage of:

  1. Maps as possible inputs instead of explicitly defining bathymetry.
  2. Pre-existing simulation library of shallow water calculations.
  3. The application will focus on quantifying the uncertainties in the predicted response, given that the properties of the building and the initiation conditions are not known exactly.

The design of the Hydro-UQ application is such that researchers are able to modify its backend to utilize their own application in the workflow computations. This will ensure researchers are not limited to using the default applications provided and will enable them to provide their applications for others to use.
