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 Model domain Terrestrial One-line model description 2-D model tracking cosmogenic nuclides and mixing in landslide terrain Extended model description The model tracks both surface CRN concentration and concentration eroded off hillslopes into fluvial network in a simplified landscape undergoing both landslide erosion and more steady 'diffusive-like' erosion. Sediment mixing is allowed in the fluvial network. Code can be used to help successfully develop CRN sampling procedures in terrains where landslides are important.

No If above answer is no, provide end year model development 2008 Code development status When did you indicate the 'code development status'? Model availability As code Source code availability (Or provide future intension) Through CSDMS repository Source web address Source csdms web address https://github.com/csdms-contrib/cosmoland Program license type Other Program license type other -- Memory requirements <512MB Typical run time minutes to days Describe input parameters Input: Landslide: recurrence interval, size parameters Cosmogenic: production rate, decay rate, attenuation, density diffusive erosion rate drainage basin size, critical drainage area for a channel River channel scaling parameters: width, sediment depth, drainage density Input format Other input format matlab .m file Describe output parameters Mass, atoms, landslide size, fluvial residence time, mixed mass and atoms fraction Output format Other output format .mat file Pre-processing software needed? No Describe pre-processing software Post-processing software needed? No Describe post-processing software Visualization software needed? Yes If above answer is yes Matlab Other visualization software Describe processes represented by the model Tracking of cosmogenic nuclides on surface and in fluvial system of a landslide dominated drainage basin Describe key physical parameters and equations Cosmogenic nuclide production decay with depth. Power-law distribution of landslide size. Calculates a fluvial storage reservoir. Describe length scale and resolution constraints Drainage basin size controls the length of the model runs. Cell size should not be increased to shorten model runs. Describe time scale and resolution constraints Yearly timesteps. Most runs go for 500,000 yrs or more. Describe any numerical limitations and issues Matlab may max out memory if drainage basin is too large. Since this is a simplified landscape with wrap-around boundary conditions, one workaround is to do numerous smaller runs and add the output. Describe available calibration data sets Upload calibration data sets if available: Describe available test data sets Upload test data sets if available: Describe ideal data for testing CRN data both hillslope and fluvial. Do you have current or future plans for collaborating with other researchers? Not currently. Is there a manual available? No Upload manual if available: Model website if any Model forum / discussion board 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:
