Summary Contact Technical specs In/Output Process Testing Other Component info Also known as Model type Modular Model part of larger framework Note on status model Date note status model Incorporated models or components: Spatial dimensions 2D Spatial extent Landscape-Scale, Watershed-Scale, Reach-Scale, Patch-Scale Model domain One-line model description Python software framework for writing, assembling, and running 2D numerical models Extended model description Landlab is a Python software package for creating, assembling, and/or running 2D numerical models. Landlab was created to facilitate modeling in earth-surface dynamics, but it is general enough to support a wide range of applications. Landlab provides three different capabilities: (1) A DEVELOPER'S TOOLKIT for efficiently building 2D models from scratch. The toolkit includes a powerful GRIDDING ENGINE for creating, managing, and iterative updating data on 2D structured or unstructured grids. The toolkit also includes helpful utilities to handle model input and output. (2) A set of pre-built COMPONENTS, each of which models a particular process. Components can be combined together to create coupled models. (3) A library of pre-built MODELS that have been created by combining components together.

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 Source code availability (Or provide future intension) Through web repository Source web address https://github.com/landlab/landlab/ Source csdms web address Program license type GPL v2 Program license type other Memory requirements variable Typical run time variable Describe input parameters Because this is a toolkit for model building, there are no set input parameters. Rather, developers use the code to create their own models, with their own unique inputs. The ModelParameterDictionary tool provides formatted ASCII input for model parameters. The I/O component also handles input of digital elevation models (DEMs) in standard ArcInfo ASCII format. Input format ASCII Other input format Describe output parameters Gridding component provides ASCII and/or netCDF output of grid geometry. Output format ASCII Other output format 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 Python, VisIt Describe processes represented by the model As of autumn 2013, the library of process components includes the following: - diffusion (for conductive heat transport, soil transport over terrain, or other applications of diffusion theory) - single-direction flow routing over topography - detachment-limited stream erosion - solar radiation input as a function of topography, latitude, and time - evapotranspiration - soil-moisture dynamics - stochastic storm generation - stochastic wildfire generation - impact cratering - overland flow / flood inundation Describe key physical parameters and equations See documentation at: http://landlab.readthedocs.org Describe length scale and resolution constraints Depends on application/process Describe time scale and resolution constraints Depends on application/process Describe any numerical limitations and issues Depends on application/process Describe available calibration data sets Varies among components and models Upload calibration data sets if available: Describe available test data sets Varies among components and models. All components include internal consistency checks using the doctest package. Upload test data sets if available: Describe ideal data for testing Varies among components and models Do you have current or future plans for collaborating with other researchers? Landlab was created for the scientific community to use and share. We encourage anyone interested to contribute new components and models. Is there a manual available? Yes Upload manual if available: Model website if any Documentation online at http://landlab.readthedocs.org Model forum / discussion board Comments This part will be filled out by CSDMS staff OpenMI compliant No not possible BMI compliant No not possible WMT component Not yet"Not yet" is not in the list (Yes, In progress, No but possible, No not possible) of allowed values for the "Code CMT compliant or not" property.
