Summary

These data represent input and estimates from a medium-resolution (1:100,000 scale) NHDPlus SPAtially Referenced Regression on Watershed attributes (SPARROW) model for the Chesapeake Bay watershed (CBSS_v2). The model spatially correlates long-term mean annual suspended-sediment flux in 113 non-tidal streams to likely upland and stream-corridor sources, landscape factors affecting upland sediment transport and delivery to stream corridors, and fluvial and reservoir retention representing the early 2000 time period. The item COMID is a common related field between the data file and the spatial component (catchments) in NHDPlus version 1.0.

Purpose

The purpose of these data are to present input and estimates of sediment sources from a medium-resolution (1:100,000 scale) NHDPlus hydrologic network for the Chesapeake Bay watershed. These data can be used to assess magnitudes of sediment supply and transport at regional scales.
