Describe input parameters grid : ModelGrid

A Landlab square cell raster grid object

latero_mech : string, optional (defaults to UC)
Lateral erosion algorithm, choices are "UC" for undercutting-slump model and "TB" for total block erosion

alph : float, optional (defaults to 0.8)
Parameter describing potential for deposition, dimensionless

Kv : float, node array, or field name
Bedrock erodibility in vertical direction, 1/years

Kl_ratio : float, optional (defaults to 1.0)
Ratio of lateral to vertical bedrock erodibility, dimensionless

solver : string
Solver options:
(1) 'basic' (default): explicit forward-time extrapolation. Simple but will become unstable if time step is too large or if bedrock erodibility is very high.
(2) 'adaptive': subdivides global time step as needed to prevent slopes from reversing.

inlet_node : integer, optional
Node location of inlet (source of water and sediment)

inlet_area : float, optional
Drainage area at inlet node, must be specified if inlet node is "on", m^2

qsinlet : float, optional
Sediment flux supplied at inlet, optional. m3/year

flow_accumulator : Instantiated Landlab FlowAccumulator, optional
When solver is set to "adaptive", then a valid Landlab FlowAccumulator must be passed. It will be run within sub-timesteps in order to update the flow directions and drainage area.
