cliffs-src

Source code for a numerical model (Cliffs) to simulate tsunami propagation and run-up on land.

Cliffs Features

• Shallow-Water approximation with an option to emulate physical dispersion
• Use of Cartesian or spherical (lon/lat) coordinates
• 1D and 2D configurations, including 1-D channels with varying width - domain type is detected automatically
• Structured colocated grid with (optionally) varying spacing
• Runup on land
• Variety of starting/forcing options: bottom deformation, surface deformation, boundary input, or combination of those
• Output options: various
• Grid nesting with one-way coupling
• Parallelized with OpenMP
• NetCDF format of input/output data

Modeling set-up examples

• Runup onto a sloping beach
• Hokkaido 1993 (Okushiri) Tsunami

(to run the examples, see Cliffs User Manual for instructions)
