# Overview

Seven different benchmark tests have been developed for the workshop, among which two will be chosen as being required of all participants. Tests based on laboratory data sets fall into two general categories: Tests based on sliding solid bodies, or tests based on granular media. Cases in each category may also be either subaerial or submarine. One field case is also included, involving a documented submarine slide.

The set of benchmarks includes:

- Benchmark 1: 2D - Submarine solid block slide with elliptic cross section (Grilli and Watts, 2005)
- Benchmark 2: 3D - Submarine solid block slide with elliptic cross sections in two dimensions (Enet and Grilli, 2007)
- Benchmark 3: 3D - Subaerial and Submarine solid slide with rectangular plan and vertical sides, (Liu et al., 2005)
- Benchmark 4: 2D - Deformable submarine slide (Grilli et al, 2016)
- Benchmark 5: 2D - Deformable subaerial slide (Viroulet et al., 2014)
- Benchmark 6: 3D - Deformable subaerial slide (Mohammed and Fritz, 2012)
- Benchmark 7: 3D - Field case, Port Valdez, AK 1964 (Nicolsky et al., 2013)

** All participating modelers must complete Benchmark Problems #2 and #4 and are strongly encouraged to try Benchmark Problem #7. ** Simulation of other problems, while strongly encouraged, is optional.

Information about the individual benchmark problems can be found by using the links to the left. Also, the data for ALL problems will be made available as a single zip file here shortly.
