One-line model description	The ChannelProfiler extracts and plots channel networks from a landlab grid.
Extended model description	In order to extract channel networks, the flow connectivity across the grid must already be identified. This is typically done with the FlowAccumulator component. However, this component does not require that the FlowAccumulator was used. Instead it expects that the following at-node grid fields will be present: 'flow__receiver_node' 'flow__link_to_receiver_node' The ChannelProfiler can work on grids that have used route-to-one or route-to-multiple flow directing.

Describe input parameters	grid : Landlab Model Grid instance, required channel_definition_field : field name as string Name of field used to identify the outlet and headwater nodes of the channel network. Default is "drainage_area". minimum_outlet_threshold : float, optional Minimum value of the channel_definition_field to define a watershed outlet. Default is 0. minimum_channel_threshold : float, optional Value to use for the minimum drainage area associated with a plotted channel segment. Default values 0. number_of_watersheds : int, optional Total number of watersheds to plot. Default value is 1. If value is greater than 1 and outlet_nodes is not specified, then the number_of_watersheds largest watersheds is based on the drainage area at the model grid boundary. If given as None, then all grid cells on the domain boundary with a stopping field (typically drainage area) greater than the minimum_outlet_threshold in area are used. main_channel_only : Boolean, optional Flag to determine if only the main channel should be plotted, or if all stream segments with drainage area less than threshold should be plotted. Default value is True. outlet_nodes : length number_of_watersheds iterable, optional Length number_of_watersheds iterable containing the node IDs of nodes to start the channel profiles from. If not provided, the default is the number_of_watersheds node IDs on the model grid boundary with the largest terminal drainage area. cmap : str A valid matplotlib cmap string. Default is "viridis".
