Drainage density is calculated as the inverse of the minimum distance to channel averaged over all nodes in the Landlab domain. +
Very little constraint; runs quickly on large grids. +
Though the component can use a simple slop … Though the component can use a simple slope-area threshold to delineate channels, it is much more preferable to use some channel-head extraction method like those of Passalacqua et al (2010, Journal of Geophysical Research), Pelletier (2013, Water Resources Research), or Clubb et al (2014, Water Resources Research).bb et al (2014, Water Resources Research). +

The Landlab Drainage Density component cal … The Landlab Drainage Density component calculates landscape-averaged drainage density, defined as the inverse of the mean distance from any pixel to the nearest channel. The component follows the approach defined in Tucker et al (2001, Geomorphology). The drainage density component does not find channel heads, but takes a user-defined channels mask.s, but takes a user-defined channels mask. +
