Identifying The Stream Erosion Potential Of Cave Levels In Carter Cave State Resort Park, Kentucky, Usa, Eric Peterson, Brianne Jacoby, Toby Dogwiler Dec 2010

Identifying The Stream Erosion Potential Of Cave Levels In Carter Cave State Resort Park, Kentucky, Usa, Eric Peterson, Brianne Jacoby, Toby Dogwiler

Eric Wade Peterson

Cave levels, passages found at similar elevations and formed during the same constant stream base level event, reveal information about paleoclimates and karst geomorphology. The investigation presented here examines how Stream Power Index (SPI) relates to cave levels. The study area, Carter Caves State Resort Park (CCSRP), is a fluviokarst system in northeastern Kentucky containing multiple cave levels. SPI deter-mines the erosive power overland flow based on the assumption that flow accumulation and slope are proportional to potential for sediment entrainment. Part of this digital terrain analysis requires the creation of a flow accumulation raster from a digital elevation model …

Using Gis To Identify Cave Levels And Discern The Speleogenesis Of The Carter Caves Karst Area, Kentucky, Lara Harlan, Eric Wade Peterson, Toby J. Dogwiler Dec 2010

Using Gis To Identify Cave Levels And Discern The Speleogenesis Of The Carter Caves Karst Area, Kentucky, Lara Harlan, Eric Wade Peterson, Toby J. Dogwiler

Cave level delineation often yields important insight into the speleogenetic history of a karst system.Various workers in the Mammoth Cave System (MCS) and in the caves of the Cumberland Plateau Karst(CPK) have linked cave level development in those karst systems with the Pleistocene evolution of theOhio River. This research has shown that speleogenesis was closely related to the base level changesdriven by changes in global climate. The Carter Caves Karst (CCK) in northeastern Kentucky has beenpoorly studied relative to the MCS to the west and the CPK karst to the east. Previously, no attempt hadbeen made to delineate speleogenetic levels …

Temporal Stability Of Cave Sediments, Kevin Hughes, Eric Wade Peterson Dec 2010

Temporal Stability Of Cave Sediments, Kevin Hughes, Eric Wade Peterson

Eric Wade Peterson

Sediments within cave systems have been examined concerning source, mineralogy, and transport potential. While sediments in the thalweg are very mobile, the entrainment potential of the sediment piles has not been examined. Over the course of nine months, sediment piles in a Missouri cave were sampled to determine the stability of the piles and of the sediment properties. Sediment cores were analyzed for dry bulk density (ρd), porosity (n), volumetric wetness (θ), organic content (O.C.), hydraulic conductivity (K), and sediment particle size distribution. Observational evidence, deposited sediment and deformation of previous …
