Physiography

Physiography, Geology, and Soil Classification

Young’s Branch (YB), located on a portion of the Wayne National Forest in Lawrence County, is located on bedrocks belonging to the Allegheny group. By contrast, Bluegrass Ridge (BR), the other study area in Lawrence County, is underlain by sedimentary strata of the Connemaugh group. The bedrock complex includes a combination of sandstones, sandy shales (or siltstones), and clay shales (Denton e...

Overview of the Physiography and Vegetation of Virginia

Stretching over 750 km (450 mi) east to west from the Atlantic Ocean to the Appalachian mountains, the Commonwealth of Virginia spans five of the more than 20 major physiographic provinces found in North America (Fenneman 1938), making it one of the most diverse landscapes both topographically and floristically in the East. Because of its location between the glaciated, mountainous regions of t...

Soil and ground water salintty and their relations to physiography

Howmuch influence does landscape-scale physiography have on air temperature in a mountain environment?

Spatio-temporal patterns of temperature in mountain environments are complex due to both regional synoptic-scale and landscape-scale physiographic controls in these systems. Understanding the nature and magnitude of these physiographic effects has practical and theoretical implications for the development of temperature datasets used in ecosystem assessment and climate change impact studies in ...

Assessment of regional variation in streamflow responses to urbanization and the persistence of physiography.

Aquatic ecosystems are sensitive to the modification of hydrologic regimes, experiencing declines in stream health as the streamflow regime is altered during urbanization. This study uses streamflow records to quantify the type and magnitude of hydrologic changes across urbanization gradients in nine U.S. cities (Atlanta, GA, Baltimore, MD, Boston, MA, Detroit, MI, Raleigh, NC, St. Paul, MN, Pi...
