STATSGO Soil Characteristics: Soil Attributes, Layer Attributes
This tabular data set represents the STATSGO Soil Layer 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 LAYER table from the "STATSGO soil characteristics for the conterminous United States" produced by the United States Geological Survey (Wolock, 1997). The variables included are water-table depth, soil erodibility (k-fact), soil erodibility for the uppermost soil horizon (k-factup), permeability, average water capacity, bulk density, percent organic material, rainfall and runoff factor ("R factor" of Universal Soil Loss Equation; average annual value for period 1971-2000), average value of percent by weight of soil material less than 3 inches in size and passing a No. 10 sieve (2 mm), average value of percent by weight of soil material less than 3 inches in size and passing a No. 200 sieve (.074 mm), average value of percent by weight of soil material less than 3 inches in size and passing a No. 4 sieve (5 mm), and rock depth. 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).
