Summary Contact Technical specs In/Output Process Testing Other Component info Also known as Model type Single Model part of larger framework Note on status model Date note status model Incorporated models or components: Spatial dimensions 2D Spatial extent Global Model domain Terrestrial, Geodynamic, Climate One-line model description Global Scalable Paleo Landscape Evolution Extended model description gospl is able to simulate global-scale forward models of landscape evolution, dual-lithology (coarse and fine) sediment routing and stratigraphic history forced with deforming plate tectonics, paleotopographies and paleoclimate reconstructions. It relates the complexity of the triggers and responses of sedimentary processes from the complete sediment routing perspective accounting for different scenarii of plate motion, tectonic uplift/subsidence, climate, geodynamic and sedimentary conditions.

Yes If above answer is no, provide end year model development Code development status Active When did you indicate the 'code development status'? 2020 Model availability As code Source code availability (Or provide future intension) Through web repository Source web address https://github.com/Geodels/gospl Source csdms web address Program license type GPL v3 Program license type other Memory requirements Typical run time Describe input parameters paleo-landscape, paleo-climate, plate reconstruction Input format ASCII, Binary Other input format Describe output parameters evolving landscape, stratigraphy Output format Binary Other output format Pre-processing software needed? Yes Describe pre-processing software Available as jupyter notebooks based on CSV and numpy compressed arrays format. The documentation contains some workflows and functions that helps, among others, to pre-process netCDF elevation and climate dataset, plate velocity files and to create an unstructured spherical mesh used as input for gospl. Post-processing software needed? Yes Describe post-processing software Python workflows. Outputs are generated as compressed hdf5 files (The HDF Group, 2000-2010) that can be simply visualise as a temporal series in ParaView (Ahrens et al., 2005). In addition, post-processing scripts are also provided to build the output as VTK (Schroeder et al., 2006) or netCDF files (Brown et al., 1993) and to extract some specific information from the results such as erosion deposition thicknesses, stratigraphic records or river sediment load over time. Visualization software needed? Yes If above answer is yes Other visualization software Paraview Describe processes represented by the model global-scale forward models of landscape evolution, dual-lithology (coarse and fine) sediment routing and stratigraphic history forced with deforming plate tectonics, paleotopographies and paleoclimate reconstructions. Describe key physical parameters and equations • river incision using the stream power law (Howard et al., 1994) based on a multiple flow direction approach and an implicit parallel implicit drainage area method (Richardson et al., 2014), • inland river deposition in depressions computed using priority-flood techniques (Barnes et al., 2014), • dual-lithology marine deposition at river mouth based on a diffusion algorithm (Rivenaes, 1992), • hillslope processes in both marine and inland areas (Salles, 2019), and • sediment compaction as stratigraphic layers geometry and properties changes (Sclater & Christie, 1980; Yuan et al., 2019). Describe length scale and resolution constraints global scale (5 to 100 km). gospl can be used with different mesh resolutions enabling better representation of surface processes in regions of interest (e.g., specific basins, continental regions) while using lower resolutions to save memory allocation in other parts (deep marine regions for example). Describe time scale and resolution constraints long term (several millions of years) problems. Describe any numerical limitations and issues Documentation provides a description of the available processes and associated limitations: https://gospl.readthedocs.io/en/latest/tech_guide/index.html Describe available calibration data sets The user guide covers essential features of gospl, mostly in the form of interactive Jupyter notebooks and Python scripts. https://gospl.readthedocs.io/en/latest/user_guide/index.html Upload calibration data sets if available: Describe available test data sets + data structure used in gospl input file, + how to generate initial conditions like topography, precipitation and tectonic maps to force a simulation, + how to extract some of the output from the model results to visualise them in Jupyter notebooks, + how to run sequence of backward/forward gospl models using Python functions, + how to set a script for running gospl on HPC. Upload test data sets if available: Describe ideal data for testing It can be used to test different hypothesis related to Earth past evolution and to characterise the role of several drivers such as precipitation, dynamic topography, sea-level on Earth landscape evolution and sedimentary basins formation.
