Pseudo-3D Electrical Resistivity Investigation of an Area in Proximity to the Tumbling Creek Cave, Taney County, Missouri

Abstract

Three pseudo-3D ERT data sets were acquired at the southeast area of the Tumbling Creek Cave, Taney County, Missouri. The objective of the study was to better delineate subsurface geologic structures and the hydrologic processes in the discharge area of the creek. The top of bedrock was mapped and the orientations of prominent dissolution-widened joints were delineated in the study area. The ERT results showed the bedrock was dissected by prominent joints trending in the north, northeast and northwest directions in the area. The jointing patterns observed are consistent with the flow patterns exhibited by the Tumbling creek and other creeks around the study area. It is a standard practice in geophysical investigations to constrain geophysical interpretations with ground truth. But due to the unavailability of boring control in the study area, the interpretation of the ERT data was based on results of previous ERT studies in southern Missouri.
