One-line model description Multidirectional flow routing using a novel method.
Extended model description This class implements Voller, Hobley, and Paola’s experimental matrix solutions for flow routing. The method works by solving for a potential field at all nodes on the grid, which enforces both mass conservation and flow downhill along topographic gradients. It is order n and highly efficient, but does not return any information about flow connectivity.

Options are permitted to allow “abstract” routing (flow enforced downslope, but no particular assumptions are made about the governing equations), or routing according to the Chezy or Manning equations. This routine assumes that water is distributed evenly over the surface of the cell in deriving the depth, and does not assume channelization. You will need to back- calculate channel depths for yourself using known widths at each node if that is what you want.

Describe input parameters grid : ModelGrid

A grid.

method : {'D8', 'D4'}, optional
Routing method ('D8' is the default). This keyword has no effect for a Voronoi-based grid.

flow_equation : {'default', 'Manning', 'Chezy'}, optional
If Manning or Chezy, flow is routed according to the Manning or Chezy equation; discharge is allocated to multiple downslope nodes proportional to the square root of discharge; and a water__depth field is returned. If default, flow is allocated to multiple nodes linearly with slope; and the water__depth field is not calculated.

Chezys_C : float, optional
Required if flow_equation == 'Chezy'.

Mannings_n : float, optional
Required if flow_equation == 'Manning'.
