Proof-of-Concept

Directory that contains model input and output files used to produce Figure 6. The models were run with a modified version of the CrunchTope executable used in Golla et al. (2021; https://doi.org/10.1016/j.epsl.2021.116988) and with PETSc 3.20.4 (https://petsc.org/release/).

DustToySteadyState

Subdirectory that contains model input and output files used to produce the starting point for dust application in the proof of concept models. The restart (.rst) file produced by running this model is suppled as a starting point to the remaining subdirectories in this Proof-of-Concept simulation

UnreactiveModel-scenario1

Subdirectory that contains model input and output files for a simulation in which an inert dust is applied to the top of the DustToySteadyState weathering profile

ReactiveModel-scenario2a

Subdirectory that contains model input and output files for a simulation in which a moderately soluble dust is applied to the top of the DustToySteadyState weathering profile

ReactiveModel-scenario2b

Subdirectory that contains model input and output files for a simulation in which a highly soluble dust is applied to the top of the DustToySteadyState weathering profile

SapineCaseStudy

Directory that contains model input and output files used to produce Figures 7-9. The models were run with a modified version of the CrunchTope executable used in Golla et al. (2021; https://doi.org/10.1016/j.epsl.2021.116988) and with PETSc 3.20.4 (https://petsc.org/release/).

SSModel

The original simulation developed by Golla et al. (2021; https://doi.org/10.1016/j.epsl.2021.116988). The restart (.rst) file produced by running this model is suppled as a starting point to the remaining subdirectories in this SapineCaseStudy simulation

DustDepositionModel

Subdirectory that contains model input and output files for a simulation in which exogenous dust is applied to the top of the SSModel weathering profile for the Sapine watershed.
