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"...

In many riparian corridors of the semi-arid west, stream incision has resulted in lowered water tables, basin big sagebrush (Artemisia tridentata var. tridentata Nutt.) encroachment and the loss of the dominant herbaceous vegetation. To determine the potential for restoring basin big sagebrush-dominated riparian corridors to greater herbaceous cover, a fall prescribed burn on sites with relatively shallow (-153 to -267 cm) and deep (-268 to ≥ -300 cm) water tables was conducted. We evaluated the separate and interacting effects of water table depth and burning on total soil C and N, soil nutrient availability, and soil enzyme activities by microsite (sagebrush subcanopy, sagebrush interspace), and soil depth (ash/liter,...

The dataset contains simulated net primary productivity (NPP) and greenhouse gas emissions (CH4, N2O, CO2) under a series of combinations of soil salinities (0.1, 0.5, 1, 2, 4, 6, 8, 10 psu) and water table depth (WTDs) (-30, -20, -10, -5, 0, 5, 10, 20, 30 cm) for tidal forest and oligohaline marsh sites along the Savannah River and Waccamaw River, USA.
