One-line model description Component to accumulate flow and calculate drainage area.
Extended model description Provides the FlowAccumulator component which accumulates flow and calculates drainage area. FlowAccumulator supports multiple methods for calculating flow direction. Optionally a depression finding component can be specified and flow directing, depression finding, and flow routing can all be accomplished together.

Describe input parameters grid : ModelGrid

A Landlab grid.

surface : field name at node or array of length node
The surface to direct flow across.

flow_director : string, class, instance of class.
A string of method or class name (e.g. 'D8' or 'FlowDirectorD8'), an uninstantiated FlowDirector class, or an instance of a FlowDirector class. This sets the method used to calculate flow directions.
Default is 'FlowDirectorSteepest'

runoff_rate : field name, array, or float, optional (m/time)
If provided, sets the runoff rate and will be assigned to the grid field 'water__unit_flux_in'. If a spatially and and temporally variable runoff rate is desired, pass this field name and update the field through model run time. If both the field and argument are present at the time of initialization, runoff_rate will *overwrite* the field. If neither are set, defaults to spatially constant unit input. Both a runoff_rate array and the 'water__unit_flux_in' field are permitted to contain negative values, in which case they mimic transmission losses rather than e.g. rain inputs.

depression_finder : string, class, instance of class, optional
A string of class name (e.g., 'DepressionFinderAndRouter'), an uninstantiated DepressionFinder class, or an instance of a DepressionFinder class. This sets the method for depression finding.

    • kwargs : any additional parameters to pass to a FlowDirector or

DepressionFinderAndRouter instance (e.g., partion_method for FlowDirectorMFD). This will have no effect if an instantiated component is passed using the flow_director or depression_finder keywords.
