Section 4: Migrating Trench Test Case
Reproduce Thetis results with:
#!bash
$ python trench.py
The plot created by this script is Figure 5 in the paper.
-
Section 5: Meander Test Case
Reproduce Thetis results with:
#!bash
$ python meander.py
The two plots created by this script are Figures 14a and 14b in the paper.
To verify our hydro-morphodynamics model in Thetis, we used the Telemac-Mascaret model (http://opentelemac.com/index.php/download).
The steering files for the Migrating Trench Test Case were obtained via private communication from the authors of Villaret, Catherine, et al. "First-order uncertainty analysis using Algorithmic Differentiation of morphodynamic models." Computers & Geosciences 90 (2016): 144-151.
The steering files for the Meander Test case are those for the "Yen" validation example in Sisyphe. The steering files come as part of the Telemac-Mascaret download. As stated in the paper, some Sisyphe results for the meander test case that we have presented are taken directly from Villaret et al. (2016).
