Summary Contact Technical specs In/Output Process Testing Other Component info Also known as Landlab Depth Dependent Linear Diffuser Model type Tool Model part of larger framework LandLab Note on status model Date note status model Incorporated models or components: Spatial dimensions 2D Spatial extent Landscape-Scale Model domain Terrestrial One-line model description Soil depth-dependent linear hillslope diffuser Extended model description This component implements a depth and slope dependent linear diffusion rule in the style of Johnstone and Hilley (2014). Soil moves with a prescribed exponential vertical velocity profile. Soil flux is dictated by a diffusivity, K, and increases linearly with topographic slope.

No If above answer is no, provide end year model development 2019 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/landlab/landlab/tree/master/landlab/components/depth_dependent_diffusion Source csdms web address Program license type BSD or MIT X11 Program license type other Memory requirements Typical run time Describe input parameters grid: ModelGrid Landlab ModelGrid object linear_diffusivity: float Hillslope diffusivity, m**2/yr soil_transport_decay_depth: float characteristic transport soil depth, m Input format Other input format Describe output parameters Output format Other output format 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 This component calculates the flux of soil on a hillslope according to a soil depth-dependent linear diffusion rule. Describe key physical parameters and equations Soil flux is calculated at the product of diffusivity, a characteristic transport depth, and an exponential velocity profile based on total soil depth. Describe length scale and resolution constraints Describe time scale and resolution constraints Describe any numerical limitations and issues Explicit solver can go unstable, and it is not always obvious. Make sure to check resulting soil depths in the landscape to look for instabilities. 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 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 Model forum / discussion board Comments This part will be filled out by CSDMS staff OpenMI compliant No but possible BMI compliant Yes WMT component No but possible PyMT component Yes Is this a data component Can be coupled with:
