3. Shallow Water Solvers

There are several shallow water solvers available. In this work, we have focused on two of the primary ones of interest to the community: GeoClaw and AdCirc.

3.1. GeoClaw

GeoClaw is a part of Clawpacky that was originally developed in 1994 by Prof. Randall LeVeque and co-workers. It is available as a part of the clawpack package that uses finite volume methods for to solve linear and nonlinear hyperbolic systems. It employs high-resolution Godunov0type methods with limiters in a general framework applicable to wave-related problems and thus often used for tsunami modeling. More information can be found on the website of Clawpack.

In this documentation, we will discuss aspects of particular importance to the Hydro-UQ platform that includes the input and output formats of the GeoClaw files. The Hydro-UQ tool allows the users to upload their own GeoClaw input files.

• Theory
• Topography
• Run-time parameters
• Outputs

3.2. AdCirc

At present, AdCirc is not supported. Please contact us if you would like to use AdCirc.

3.3. SimCenter formats

Development of file standards can help in the sustainable growth of community projects. SimCenter proposes the below formats for storing information related to the shallow water solvers.
