Longitudinal Profile And Sediment Mobility As Geomorphic Tools To Interpret The History Of A Fluviokarst Stream System, John Woodside, Eric Wade Peterson, Toby Dogwiler
Longitudinal Profile And Sediment Mobility As Geomorphic Tools To Interpret The History Of A Fluviokarst Stream System, John Woodside, Eric Wade Peterson, Toby Dogwiler
International Journal of Speleology
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 …

The Munzur Mountains were subjected to extensive and repeated glaciations during the Pleistocene. The presence of an active glacier in the region was not verified until this study. Here, we used remote sensing methods to identify and locate the glaciers and verified the activity of the largest glacier in the field. We named this glacier the Şahintaşı Glacier and studied it using 3D ArcGIS spatial analyses overlaid on high-resolution Geographical Information Systems (GIS) satellite images. The most current version of LANDSAT 8 (acquired on 14.08.2013) supplied the remote sensing information. We used principal component analysis on the data. The precise …
