Identification of groundwater emergence in a naturally bedded culvert in Conway, PA

This project focused on identifying groundwater seep locations and estimating flux rates of groundwater emerging into a 0.5 km reach of a naturally-bedded culvert confining a stream channel in an industrial area. Two steel-reinforced 1-cm diameter fiber optic cables were installed approximately 20 cm into streambed sediment in 4 transects along the length of the tunnel (See layout figure). The two fibers were connected a Silixa Ultima DTS Interrogator in a double-ended fashion, which collected temperature data from each of the four channels at 10 minute intervals. Data was collected Aug 18 – 31, 2020 and again January 9, 2021 to March 12, 2021.
