Examples¶
There are two idealized examples to illustrate the capabilites of D-Claw: gully and radial slide. In addition, we provide a list of field-scale application maintained in separate repositories.
Idealized examples¶
Gully¶
The gully example is located within dclaw/examples/gully and is an idealized example of a debris flow moving down a confined channel and then out onto an unconfined plane. To run this example, first install D-Claw and then navigate to the gully application directory and execute:
make .exe
make input
make .plots
Radial Slide¶
The radial slide example is located within dclaw/examples/radial_slide and is an ideallized example of a landslide-tsunami from a radially symmetric island. To run this example, first install D-Claw and then navigate to the radial slide application directory and execute:
make .exe
make input
make .plots
Idealized Landslide¶
Python scripts used to generate a range of idealized landslide examples are located in dclaw/examples/idealized_sides. This example creates a circular patch of landslide material on a simplified slope (a negative exponent that decreases in elevation and slope as the x-coordinate increases). By running:
python driver.py
A series of simulations are generated in individual directories located in results. These may all be run by executing:
python run.py
Alternatively, one may navigate to a specific application directory within results and run the simulation by executing:
make .exe
make input
make .plots
If one is interested in comparing the figures generated by of two directories, use the imagediff.py function provided by clawutil. For example:
python ../../../../clawutil/src/python/clawutil/imagediff.py \
IDEAL_001_K900_m62_P35_depth5_src-1_O1_R0/_plots \
IDEAL_002_K900_m62_P35_depth5_src-1_O1_R1/_plots
Field-scale examples¶
Note
This is an incomplete list and will be updated as more examples are disseminated.
Simulations of Barry Arm landslide complex¶
Barnhart and Collins (2025) provide an example of setting up and running multiple simulations of the Barry Arm landslide complex in support of Barnhart and others (2025).
Simulation of the 2024 Surprise Inlet landslides¶
Barnhart (2025) provides an example of setting up and running a single simulation of the 2024 Surprise Inlet landslides in support of Karasözen and others (2025).
