Field Validation Of Dem And Gis Derived Longitudinal Stream Profiles, Kathryn Schroeder, Eric Peterson, Toby Dogwiler
Eric Wade Peterson
Longitudinal stream profiles provide valuable information concerning geomorphic features and energy states in a stream. Traditionally, stream profiles have been generated by field surveying or topographic map analysis. The continued growth of digital data and Geographic Information Systems (GISs) provide another method by which to achieve stream profile generation. This work examines the effectiveness of digital data, digital elevation models (DEM), and GIS to construct stream profiles. To determine the most effective and accurate data for profile generation, profiles were created using 1-meter (1-m) and 3-meter (3-m) DEMs developed from LiDAR data. Additionally, stream profiles were created from unfilled DEMs …
Longitudinal Profile And Sediment Mobility As Geomorphic Tools To Interpret The History Of A Fluviokarst Stream System, John Woodside, Eric Peterson, Toby Dogwiler
Longitudinal Profile And Sediment Mobility As Geomorphic Tools To Interpret The History Of A Fluviokarst Stream System, John Woodside, Eric Peterson, Toby Dogwiler

The complex drainage systems within karst settings can result in atypical longitudinal profiles. Features, such as cave entrances, can be expressed as anomalous ‘bumps’ in the longitudinal profile of a stream if downcutting has continued upstream of the area in which the water is pirated to the subsurface. Horn Hollow, a fluviokarst valley located in Carter Caves State Park Resort in northeastern Kentucky, was examined for these types of features. The objectives of this study were to determine if sediment mobility can be used as a proxy for anomalous areas along the profile of the valley and if detailed cross-sections …

Identifying cave levels provides insight into cave development and climatic changes that have affected a karst system over time. Cosmogenic dating has been used to interpret levels in Mammoth Cave and the Cumberland Plateau. This absolute dating technique has proven successful in determining cave paleoclimates and regional geomorphic history, but is expensive. The study presented here is a preliminary method to cosmogenic dating that can outline a region’s speleogenesis using a Geographic Information System (GIS) and published denudation rates. The Carter Cave system in northeastern Kentucky is within the karst landscape found along the western edge of the Appalachians and …
