Model:BatTri + (To generate a grid, the user should input … To generate a grid, the user should input the boundary node information, boundary segment information and hole (or island) information in form of a .poly file, as described in the Triangle manual (http://www.cs.cmu.edu/~quake/triangle.poly.html). These input nodes and segments in the .poly file are forced into the triangulation of the domain. Alternatively (and this is a strong point of BATTRI), all this information can be created from only a bathymetric dataset with the use of the editing options of BATTRI (see Option 0 in Running BATTRI section). This process may require manual deleting of unnecessary segments and nodes, closing of islands by segment adding, addition of an open ocean boundary segment, etc.As a starting point, ordered digital coastline node data can be extracted from the National Geophysical Data Center's webpage (https://www.ngdc.noaa.gov/mgg/shorelines/) at various scales ranging from 1:70,000 to 1:5,000,000. If the coastline is very highly resolved, causing an excessive number of elements along the shoreline, the routine "xy_simplify.m" can be used to reduce the number of nodes to the desired resolution. Remember to format this data into a .poly file, consisting of nodes and segments, before inputting into BATTRI. To refine an already created grid, the user can input the above referenced information either in the form of a previously created .poly file or in the form of NML standard .nod, .ele and .bat files (see next section, Running BATTRI). files (see next section, Running BATTRI).)

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.

Layer thickness can be zero, though the entirety of Lithology must have non-zero thickness.ids : ndarray of shape `(n_layers, )` or `(n_layers, n_nodes)` Values of rock type IDs corresponding to each layer specified in **thicknesses**. A single layer may have multiple rock types if specified by the userattrs : dict Rock type property dictionary. See class docstring for example of required format.layer_type : str, optional Type of Landlab layers object used to store the layers.

Model:LakeMapperBarnes + (grid : ModelGrid A Landlab grid. … grid : ModelGrid A Landlab grid. surface : field name at node or array of length node The surface to direct flow across. method : {'Steepest', 'D8'} Whether or not to recognise diagonals as valid flow paths, if a raster. Otherwise, no effect. fill_flat : bool If True, pits will be filled to perfectly horizontal. If False, the new surface will be slightly inclined to give steepest descent flow paths to the outlet. fill_surface : bool Sets the field or array to fill. If fill_surface is surface, this operation occurs in place, and is faster.Note that the component will overwrite fill_surface if it exists; to supply an existing water level to it, supply that water level field as surface, not fill_surface. redirect_flow_steepest_descent : bool If True, the component outputs modified versions of the 'flow__receiver_node', 'flow__link_to_receiver_node', 'flow__sink_flag', and 'topographic__steepest_slope' fields. These are the fields output by the FlowDirector components, so set to True if you wish to pass this LakeFiller to the FlowAccumulator, or if you wish to work directly with the new, correct flow directions and slopes without rerunning these components on your new surface.Ensure the necessary fields already exist, and have already been calculated by a FlowDirector! This also means you need to instantiate your FlowDirector **before** you instantiate the LakeMapperBarnes.Note that the new topographic__steepest_slope will always be set to zero, even if fill_flat=False (i.e., there is actually a miniscule gradient on the new topography, which gets ignored). reaccumulate_flow : bool If True, and redirect_flow_steepest_descent is True, the run method will (re-)accumulate the flow after redirecting the flow. This means the 'drainage_area', 'surface_water__discharge', 'flow__upstream_node_order', and the other various flow accumulation fields (see output field names) will now reflect the new drainage patterns without having to manually reaccumulate the discharge. If True but redirect_flow_steepest_descent is False, raises an ValueError. ignore_overfill : bool If True, suppresses the Error that would normally be raised during creation of a gentle incline on a fill surface (i.e., if not fill_flat). Typically this would happen on a synthetic DEM where more than one outlet is possible at the same elevation. If True, the was_there_overfill property can still be used to see if this has occurred. track_lakes : bool If True, the component permits a slight hit to performance in order to explicitly track which nodes have been filled, and to enable queries on that data in retrospect. Set to False to simply fill the surface and be done with it.ueries on that data in retrospect. Set to False to simply fill the surface and be done with it.)
