James Cave Epikarst Monitoring Drip Data: 2007-2018

Cave
drip measurements were made at three drip monitoring stations within James Cave
(Pulaski County, Virginia) from fall 2007 to winter 2018. Measurements were
made in mm on a 10 minute interval using HOBO® tipping bucket rain gauges and
stored on HOBO® multi-station data loggers. Measurements in mm can be converted
to ml (3.7 ml to 0.2 mm). Data were downloaded bimonthly to quarterly and
compiled to form a continuous time series.
Missing data reflect periods of instrumentation failure. The location of
cave drip monitoring sites can be found in Figure 4 of Groce-Wright (2021; http://hdl.handle.net/10919/104202). The geologic map can be found as Figure 3 in

Photos of the drip monitoring sites within the cave can be found as Figure 5 in

The
raw data were used in Groce-Wright (2021; http://hdl.handle.net/10919/104202) to
create drip hydrographs, which were analyzed using recession methods to
calculate alpha, the recession coefficient, which reflects the hydrogeologic
characteristics of the overlying epikarst (soil and weathered bedrock above the
cave), and the storage volume.
