This dataset can be linked to the NHDPlus version 2 data suite by the unique identifier COMID.  The source data is from the NAWQA Wall-to-Wall Anthropogenic Land Use Trends (NWALT) produced by James Falcone (USGS, 2015). The data provided here contains information for five time periods: 1974-1982-1992-2002-2012, compiled as described above. The units are percents. 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.
