Groundwater Data

RSLog covers the following groundwater measurements:

• Groundwater Observation During Drilling: in order to enter groundwater observed during drilling, during test hole data entry click the link Groundwater Observed During Drilling (on General tab). This will open a dialog where you can enter groundwater depth in the "Groundwater Level (ft) to Show in the Test Hole Log" textbox.
• Groundwater Measurements After Drilling: if a piezometer / well is installed in the test hole, groundwater monitoring data is entered on Instrumentation tab during test hole data entry.

Another Type of Groundwater Measurement?

If you would like to add a different type of groundwater data (e.g. water level observed after 24 hours or 48 hours from drilling), create an Extra Tags for your boreholes.

Depth vs Elevation

RSLog calculates groundwater elevation based on the groundwater depth and borehole collar elevation. If collar elevation is not available, groundwater elevation won't be calculated.

Showing Groundwater Data on Header / Footer of the Log

• As a Number: to show groundwater depth or elevation, add a Database Field element to the header or footer of the log template. Link the Source property of this element to Water Depth or Water Elevation under the Groundwater section. If data is not available for this element, "N/A" will be show on the borehole log.
• As an 'Extra Tag': to show an Extra Tag groundwater depth or elevation, add a Database Field element to the header or footer of the log template. Link the Source property of this element to your desired Extra Tag under the Extra Tags section.
• As a Table: to show groundwater depth and elevation as a table vs time, add a Database Field element to the header or footer of the log template. Link the Source property of this element to Piezometer Readings under the Groundwater section. If piezometer groundwater measurements are not available, no table is presented on the log.

Showing Groundwater Symbol on a Log Column

Groundwater depth can be shown on the following log columns: Depth Scale, Samples, Lithologic Symbol (hatch), Elevation, and Piezometer. The following options are available (see screenshot below):

• Observed During Drilling: this will be shown using symbol. Since the date for this groundwater data is same as Start Date / End Date, RSLog does not print the measurement date for this groundwater type.
• Last Piezometer Measurement: this option will show the last groundwater on the log column using the symbol. User has the option to show the date of measurement.
• All Piezometer Measurements: this option will show all groundwater measurements on the log column using the symbol. User has the option to show the date of each measurement.

Plotting Groundwater Data vs Time

When a piezometer / well is installed in a test hole, user enters a date and time for each groundwater measurement (borehole data entry page > Instrumentation tab > Groundwater Measurements section). A graph showing the variation of groundwater depth and elevation vs time is plotted on this page. This graph may be downloaded in image format (PNG).
