Where is Sediment Coming From in North Carolina?

Where is sediment coming from in North Carolina? Comparing sediment sources for HUC8 basins, data from doi.org/10.5066/P97MV16H.  A ridgeline plot shows major sediment courses in three ecoregions of NC: coastal plain, piedmont, and mountains. In the Coastal plain, stream channels and agriculture are the top sediment sources. In piedmont and mountains agriculture makes the lowest contributions, followed by development, land use change, and stream channels. The amount of sediment from stream channels is the highest and shows a wider range of sediment per year normalized by area, Mg/km2
