Hydrologic Behavior of Gullies in the South Carolina Piedmont
The Piedmont region in the United States has been eroded and gullied due to deforestation and cultivation during the 1700 and 1800. Currently, a majority of these gullies are under forest vegetation and appear stable; however, neither the hydrology of these gullies, nor their sediment contribution to surface waters, has been quantified. This study instrumented eight gullies ranging in size from...
متن کاملEffect of Soils on Water Quantity and Quality in Piedmont Forested Headwater Watersheds of North Carolina
Water quantity and quality data were compared from six headwater watersheds on two distinct soil formations, Carolina Slate Belt (CSB) and Triassic Basins (TB). CSB soils are generally thicker, less erodible, and contain less clay content than soils found in TB. TB generated significantly more discharge ⁄precipitation ratio than CSB (0.33 vs. 0.24) in the 2009 dormant season. In the 2009 growin...
متن کاملThe Impacts of a Large Hurricane on Understory Sapling Dynamics and Diversity in North Carolina Piedmont Forests, USA
We analyzed population dynamics and changes in species diversity and composition of saplings (tree or shrub stems >50 cm in height and < 1 cm diameter at breast height) during an interval lasting from 5 years before the 1996 Hurricane Fran to 5 years post-hurricane through use of permanent transects where individual sapling stems were censused annually. The study site was the Duke Forest, locat...
متن کاملSmall Reservoir Impacts on Stream Water Quality in Agricultural, Developed, and Forested Watersheds: Georgia Piedmont, USA
Small reservoirs are prevalent landscape features and an important component of headwater hydrology. Tens of thousands of small ponds, most less than a hectare, were constructed over the past century within the United States. While remote-sensing and geographic-mapping technologies assist in quantifying these features, their influence on water quality is less well understood. This study reports...
متن کاملWeathering in the Subtropical Enoree River Basin, South Carolina, Usa
The effect of watershed spatial scale on chemical weathering is inadequately known for subtropical environments. In order to determine the relationship between watershed scale and weathering chemistry, the Enoree River basin was sampled at seven different spatial scales ranging from second-order watersheds smaller than 2 km^2 to a sixth order watershed of 1840 km^2. The second-order watersheds ...
