Summary Contact Technical specs In/Output Process Testing Other Component info Also known as Model type Single Model part of larger framework LandLab Incorporated models or components: Spatial dimensions 2D Spatial extent Regional-Scale, Landscape-Scale Model domain Terrestrial One-line model description Compute fluvial erosion using stream power theory with a numerically smoothed threshold Extended model description stream_power_smooth_threshold.py: Defines the StreamPowerSmoothThresholdEroder, which is derived from FastscapeEroder. StreamPowerSmoothThresholdEroder uses a mathematically smooth threshold formulation, rather than one with a singularity.

No If above answer is no, provide end year model development 2020 Code development status Only maintenance 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 Source csdms web address Program license type BSD or MIT X11 Program license type other Memory requirements Typical run time Describe input parameters [[Describe input parameters model::grid : ModelGrid A grid. K_sp : float, array, or field name K in the stream power equation (units vary with other parameters). m_sp : float, optional m in the stream power equation (power on drainage area). n_sp : float, optional, ~ 0.5<n_sp<4. n in the stream power equation (power on slope). NOTE: NOT PRESENTLY HONORED BY StreamPowerSmoothThresholdEroder (TODO) threshold_sp : float (TODO: array, or field name) The threshold stream power. discharge_field : float, field name, or array, optional Discharge [L^2/T]. The default is to use the grid field 'drainage_area'. To use custom spatially/temporally varying rainfall, use 'water__unit_flux_in' to specify water input to the FlowAccumulator and use "surface_water__discharge" for this keyword argument. erode_flooded_nodes : bool (optional) Whether erosion occurs in flooded nodes identified by a depression/lake mapper (e.g., DepressionFinderAndRouter). When set to false, the field flood_status_code* must be present on the grid (this is created by the DepressionFinderAndRouter).
