Please work on the Watershed/Catchment delineation algorithm so that it can produce usable watersheds and catchments, like the USGS can, shown below.
Also add a basin aggregation tool, executed by the Crossing Window Selection of multiple neighboring basins/watersheds/catchments, that the engineer/designer can implement for quick post processing aggregation of the watershed model delineations into useful basins for drainage analysis, per specific project scope and requirements.
