Bankfull Indicators in Small Blackwater Streams in Peninsular Florida: Reliability and Relations with Hydrology
INTRODUCTION Bankfull stage, or the elevation at which the stream just begins to overflow onto its floodplain, is considered an important threshold in geomorphology. Bankfull discharge, the streamflow associated with that stage is considered "the...
Comparison of Changes in Runoff and Channel Cross-Sectional Area as a Consequence of Urbanization for Three Chattahoochee River Subbasins, Georgia, USA
Hydrologic analysis was performed for three similar-size Chattahoochee River, Georgia, subbasins for the period 1961-2005, each reflecting differing degrees of urbanization. Median yearly runoff volume was higher for the highly urbanized Peachtree...
In-Channel Benches in Small Watersheds: Examples from the Southern Piedmont
A knowledge of the process dynamics and forms of river sediment storage is important for understanding the impacts of climate and land use change on sediment yield, longitudinal and cross-sectional stream channel morphology, and aquatic and riparian...
Introduction: Fluvial Processes in Small Southeastern Watersheds
The seven papers in this special issue resulted from two special sessions by the same name, at the Southeastern Division of the Association of American Geographers (SEDAAG) in Knoxville, Tennessee, in November 2009. The sessions were convened to address...
Legacy Hg-Cu Contamination of Active Stream Sediments in the Gold Hill Mining District, North Carolina
The purpose of this study is to evaluate the longitudinal vends of mercury (Hg) and copper (Cu) in active channel sediments downstream from the Gold Hill mining district in the Piedmont of North Carolina. Mining for gold (Au) and Cu from 1844 to 1915...
Morphology and Channel Evolution of Small Streams in the Southern Blue Ridge Mountains of Western North Carolina
INTRODUCTION Geomorphologists have long known how basic measures of channel form relate to increasing watershed size (hydraulic geometry), with increasingly larger flows being associated with wider, deeper channels, lower gradients, and finer channel...
Temporal Variability of Bank Erosion in East Tennessee Headwater Streams
As part of a larger effort to improve water quality in the Little River watershed, we installed and monitored 45 erosion pins on 12 banks of tributaries of this east Tennessee river. Here, we examine changes in exposure of individual erosion pins and...
The LiDAR-Side of Headwater Streams: Mapping Channel Networks with High-Resolution Topographic Data
Automated channel headwater mapping methods are reviewed and three methods are used to map a small watershed in the South Carolina upper Piedmont based on high-resolution LiDAR data. First, channels were mapped manually using crenulations on 0.6-m...
