Watershed 80 Historic Well Levels, 1992-1995.

Description:
Abstract:
A network of 34 manual wells was installed on Watershed 80 in 1992 (concurrent with the installation of a similar network on Watershed 77), two years after Hurricane Hugo had devastated the Santee Experimental Forest in September 1989. This network was monitored until early 1995, and recording datalogger/sensor units were installed in a subset of wells in 1996.

Purpose:
The purpose of this network of water table wells was to provide information on spatial and temporal variation in water table level across the first-order Watershed 80 and to increase knowledge about the relationship of water table to precipitation, runoff, evapotranspiration (ET) and other related hydrologic processes.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Measurement of the network of 34 manual wells was conducted approximately every two weeks using a steel tape and pen flashlight (measuring from the top of the well to the water surface).
Logical_Consistency_Report:
Visual inspection of electronically plotted water table data and comparison with precipitation data from the Met 25 weather station on this watershed was employed to expose anomalous values for the expected water table response to rainfall.
Completeness_Report:
As noted in the abstract, water table levels in the manual well network were monitored approximately every two weeks between 1992 and 1995.
Lineage:
Methodology:
Methodology_Type: Field
Methodology_Description:
These wells were constructed with 1.5 inch diameter PVC pipe and were installed to a depth of 8-10 feet (or more) beow ground surface.

Wells were visited approximately every two weeks and the distance from the top of the well to the water surface was measured with a steel tape and pen flashlight.
Process_Step:
Process_Description:
Water level information was retrieved from field notebooks and recorded in databases (written and electronic) at the office. Using information about the height of individual wells above ground surface allowed for calculation and plotting of water table level below ground surface.

Overview_Description:
Entity_and_Attribute_Overview:
Variables included in the dataset WS80_historic_well_levels_rev2.xlsx:

Location = watershed name (WS80 = Watershed 80);
Instr_ID = well name (w28001 = post-Hugo well number 1);
Date_ = date associated with water table data (format MM/DD/YYYY); and
Depth_cm_b (alias 'Depth below ground surface') = depth, cm below ground surface, in cm (positive values represent levels above ground surface and negative values represent levels below ground surface).

The form of the well ID numbers is whwwnn, where h is an indicator of pre Hurricane Hugo versus post Hurricane Hugo, ww is the watershed number, and nn is the well number. The values of h are 1 for pre Hugo, and 2 for post Hugo. The well numbers, nn,
are in two digit format, e.g. well numbers less than 10 are represented as 0n, as opposed to just n.

All missing data were originally assigned the value "-9999"; during database development this code was changed to "null"
