Spatial dimensions	2D
Spatial extent	Continental, Landscape-Scale, Reach-Scale, Regional-Scale, Watershed-Scale
Model domain	Terrestrial
One-line model description	Landlab component for fluvial erosion/deposition.
Extended model description	The Landlab ErosionDeposition component calculates fluvial erosion and deposition of a single substrate as derived by Davy and Lague (2009, Journal of Geophysical Research). Mass is simultaneously conserved in two reservoirs: the bed and the water column. ErosionDeposition dynamically transitions between detachment-limited and transport-limited behavior, but is limited to erosion of a single substrate (e.g., sediment or bedrock but not both).

Describe input parameters	[[Describe input parameters model::Parameters ---------- grid : ModelGrid Landlab ModelGrid object K : float Erodibility constant for substrate (units vary). phi : float Sediment porosity [-]. v_s : float Effective settling velocity for chosen grain size metric [L/T]. m_sp : float Drainage area exponent (units vary) n_sp : float Slope exponent (units vary) sp_crit : float Critical stream power to erode substrate [E/(TL^2)] F_f : float Fraction of eroded material that turns into "fines" that do not contribute to (coarse) sediment load. Defaults to zero. method : string Either "simple_stream_power", "threshold_stream_power", or "stochastic_hydrology". Method for calculating sediment and bedrock entrainment/erosion. discharge_method : string Either "area_field" or "discharge_field". If using stochastic hydrology, determines whether component is supplied with drainage area or discharge. area_field : string or array Used if discharge_method = 'area_field'. Either field name or array of length(number_of_nodes) containing drainage areas [L^2]. discharge_field : string or array Used if discharge_method = 'discharge_field'.Either field name or array of length(number_of_nodes) containing drainage areas [L^2/T]. solver : string Solver to use. Options at present include: (1) 'basic' (default): explicit forward-time extrapolation. Simple but will become unstable if time step is too large. (2) 'adaptive': adaptive time-step solver that estimates a stable step size based on the shortest time to "flattening" among all upstream-downstream node pairs.]]
