Precipitation, air temperature, streamflow, and water table depths from selected wells at the Panola Mountain Research Watershed, 2001 - 2003

This dataset contains hourly average groundwater level time-series for 19 monitoring wells at the Panola Mountain Research Watershed (PMRW) from January 2001 to October 2002. The data was used in a hydrologic modeling study to test a model formulation that allowed for bi-direction fluxes between groundwater and surface water in a bucket type hydrologic model. Some wells had missing data so record lengths were not equal. The water level data were quality controlled; unexplained peaks and shifts were removed, and these periods were indicated as having no data. The modeling study used average water level data from the riparian area and from the entire catchment for calibration. Riparian groundwater levels were calculated from the 13 riparian wells, while catchment average groundwater levels were calculated from the averages of levels from the riparian (n=13) and hillslope (n=6) wells, weighted based on the proportion of their landscape unit areas in the catchment (0.83 for hillslopes and 0.17 for riparian areas). Modeling required continuous record of water levels, so levels from each well were scaled based on their minimum and maximum levels measured during the period. Hourly riparian and catchment averages were then calculated from these scaled values, thereby, utilizing all available water level observations. Well levels were reported from the bottom of the well to facilitate this scaling, but levels can be converted to depth to water table below land surface using the provided well construction specifications. In addition to the groundwater level time series, the dataset also contains hourly time series of average streamflow at two locations at PMRW (outlet of the 10 ha Upper catchment and the 41 ha Lower catchment), total precipitation and average temperature for the January 2001 to October 2003 period. The longer period for these data were used for model verification.
