The key equations and parameters are described in Shobe et al (2017, Geoscientific Model Development). Length scale should be reach or larger (~100m and up). Run time depends on grid size and resolution. Becomes very slow if run on domains with pits. Options include filling pits before running the model, or using the Landlab DepressionFinderAndRouter. Returns/updates Landlab grid fields: 'topographic__elevation' : Topographic surface elevation 'bedrock__elevation' : Bedrock surface elevation 'soil__depth' : Depth of alluvial layer on river bed 'sediment__flux' : Sediment flux out of each grid node Fluvial sediment erosion and deposition, fluvial bedrock erosion, the bedrock cover effect. Time scale will be set by discharge calculation method. The model is in general intended for annual to geological time scales, but shorter time scales may be used if Landlab dynamic flow routing components are employed. Only maintenance 2020 Yes The Landlab SPACE (Stream Power with Alluvium Conservation and Entrainment) enables modeling of bedrock, alluviated, and bedrock-alluvial rivers by simultaneously conserving mass in three reservoirs: the water column, the alluvial bed, and the underlying bedrock. SPACE allows dynamic transitions between detachment-limited, transport-limited, and intermediate states. SPACE calculates sediment fluxes, alluvial layer thickness, and bedrock erosion at all nodes within the model domain. An extended description of the model may be found in Shobe et al (2017, Geoscientific Model Development).
