Query: GeoClaw-STRICHE: A coupled model for Sediment TRansport In Coastal
  Hazard Events   GeoClaw-STRICHE is designed for simulating the physical impacts of tsunami as
it relates to erosion, transport and deposition. GeoClaw-STRICHE comprises of
three components: (1) nonlinear shallow water equations; (2)
advection-diffusion equation; (3) an equation for morphology updating. Multiple
grain sizes and sediment layers are added into GeoClaw-STRICHE to simulate
grain-size distribution and add the capability to develop grain-size trends
from bottom to the top of a simulated deposit as well as along the inundation.
Unlike previous models based on empirical equations or sediment concentration
gradient, the standard Van Leer method is applied to calculate sediment flux.
We tested and verified GeoClaw-STRICHE with flume experiment by
\citet{johnson2016experimental} and data from the 2004 Indian Ocean tsunami in
Kuala Meurisi as published in \citet{JGRF:JGRF786}. The comparison with
experimental data shows GeoClaw-STRICHE's capability to simulate sediment
thickness and grain-size distribution in experimental conditions. The agreement
between experimental and model results is generally quite good, especially for
sediment thickness, which builds confidence that sediment transport is
correctly predicted by this model. The comparison with the data from the 2004
Indian Ocean tsunami reveals that the pattern of sediment thickness is well
predicted and is of similar quality, if not better than the established
computational models such as Delft3D.
