This version is a WMT component but can also be run as a stand-alone model (see README.md). DeltaRCM is a parcel-based cellular flux routing and sediment transport model for the formation of river deltas, which belongs to the broad category of rule-based exploratory models. It has the ability to resolve emergent channel behaviors including channel bifurcation, avulsion and migration. Sediment transport distinguishes two types of sediment: sand and mud, which have different transport and deposition/erosion rules. Stratigraphy is recorded as the sand fraction in layers. Best usage of DeltaRCM is the investigation of autogenic processes in response to external forcings.]] Keywords: delta evolution, cellular automata, coastal morphodynamics, Name Mariela Perignon Type of contact Model developer Institute / Organization University of Colorado / CSDMS Postal address 1 Postal address 2 Town / City Boulder Postal code 80303 State Colorado Country United States Email address perignon@colorado.edu Phone Fax Supported platforms Unix, Linux, Mac OS, Windows Other platform Programming language Python Other program language Code optimized Single Processor Multiple processors implemented Nr of distributed processors Nr of shared processors Start year development 2016 Does model development still take place? Yes If above answer is no, provide end year model development Code development status When did you indicate the 'code development status'? Model availability As code, As teaching tool Source code availability (Or provide future intension) Through web repository Source web address https://github.com/mperignon/pyDeltaRCM_WMT Source csdms web address Program license type BSD or MIT X11 Program license type other Memory requirements Typical run time Hours Describe input parameters Modify parameters in example input file deltaRCM.yaml included in repository. Run with example script run_pyDeltaRCM.py. Modify water/sediment discharge (as number of parcels), grid size and spacing, basin geometry, mud/sand ratio, etc Input format Other input format YAML Describe output parameters Toggle on/off in input file: - PNG files of eta, stage, depth - grids of eta, stage, depth (as netCDF4) - grids of sand fraction in stratigraphy (as netCDF4) Output format Other output format netCDF Pre-processing software needed? No Describe pre-processing software Post-processing software needed? No Describe post-processing software Visualization software needed? No If above answer is yes Other visualization software Describe processes represented by the model Flux routing and sediment transport for the formation of river deltas. Resolves channel bifurcations, avulsion and migration. Can simulate subsidence (default basin-like shape, modify the Python code to customize). Can store stratigraphy (as sand fraction and thickness). Describe key physical parameters and equations [[Describe key physical parameters::See publications associated with DeltaRCM (in CSDMS model repository)]] Describe length scale and resolution constraints Domain should be 10s of Kms in x and y. Cell spacing should be 10s of meters. Describe time scale and resolution constraints Sediment and water discharge come from some physical parameters and the number of parcels chosen for each timestep. Set the number of parcels for both water and sediment to 1000s for improved resolution and speed. Describe any numerical limitations and issues Model should never be numerically unstable but its behavior depends on ratios of various parameters. If the model seems to not be "doing anything", look at the parameter initialization functions in deltaRCM_tools.py Describe available calibration data sets An intercomparison of the Matlab and Python versions of DeltaRCM is in the works. Upload calibration data sets if available: Describe available test data sets Upload test data sets if available: Describe ideal data for testing Do you have current or future plans for collaborating with other researchers? Is there a manual available? No Upload manual if available: Model website if any https://github.com/mperignon/pyDeltaRCM_WMT Model forum / discussion board Installation and execution instructions can be found in the README.md file of the GitHub repository. Comments This part will be filled out by CSDMS staff OpenMI compliant No but possible BMI compliant No but possible WMT component No but possible PyMT component Is this a data component Can be coupled with:
