    dct:description "This tabular data set represents the STATSGO Soil texture Attributes compiled for two spatial components of the NHDPlus version 2 data suite (NHDPlusv2) for the conterminous United States; 1) individual reach catchments and 2) reach catchments accumulated upstream through the river network. The source data is found in the TEXT table from the \"STATSGO soil characteristics for the conterminous United States\" produced by the United States Geological Survey (Wolock, 1997). The variables included are percent sand, silt, and clay. This dataset can be linked to the NHDPlus version 2 data suite by the unique identifier COMID.  Reach catchment information characterizes data at the local scale. Reach catchments accumulated upstream through the river network characterizes cumulative upstream conditions.  Network-accumulated values are computed using two methods, 1) divergence-routed and 2) total cumulative drainage area. Both approaches use a modified routing database to navigate the NHDPlus reach network to aggregate (accumulate) the metrics derived from the reach catchment scale. (Schwarz and Wieczorek, 2018)." ;
