Subbasins (HUC8s) of the MS-only portion of the Mississippi Sound Watershed, excluding the Mississippi Sound itself

Source: R/subbasins_ms_land.R
subbasins_ms_land.Rd

The Mississippi Sound Watershed is made up of HUC4s 0317 (Pascagoula River basin) and 0318 (Pearl River basin). This is the combination of all HUC8 units within them, clipped to cartographic boundaries (i.e. following the contours of land and islands) within only Mississippi (as MSEP's current funding only allows work within the state).

Source

National Hydrography Dataset, as downloaded from USGS on 6/4/2025 from https://prd-tnm.s3.amazonaws.com/StagedProducts/Hydrography/NHD/State/GPKG/NHD_H_Mississippi_State_GPKG.zip.

Details

The raw data were subsetted to the geopackage file msep_hucs.gpkg using the script subset_NHD.R. The subset was further processed into this final form, using the tigris package for state and cartographic boundary delineations, in make_boundaries.R. Both scripts and the subsetted geopackage file are available in the data-raw directory of the package repository at: https://github.com/CMEP-MS/msepBoundaries.
