Groundwater Elevation

Calculate the true water level referenced to elevation. Typically used for depth-to-groundwater calculations in civil and geotechnical applications, groundwater elevation is a basic conversion for water level data: it calculates the depth relative to the well elevation by subtracting the install depth from the well elevation.

Groundwater Elevation = (Well Elevation − Install Depth) + Head

• Well Elevation is typically the top-of-casing (TOC) elevation from sea level.
• Install Depth is the sensor installation depth from a point of reference, typically a wellhead.
• Head is the sensor-measured water level.

Supported sensors

Groundwater elevation can be calculated from any water level measurement.

Recommended sensors

• HYDROS 21
• CTD
• CTD-5
• CTD-10

Create a Groundwater Elevation model

1. On the Data page, click New Data.
2. Select Groundwater Elevation as the type.
3. Select one or more water level sources.
4. Edit the data stream color.
5. Edit the data stream name.
6. The sensor Position is the default value for the install depth. Edit the Height/Depth, or enter a value if none is present.
7. Enter a value for the Top of Casing / Well Elevation.
8. Select Save, then Create to finish.

The new data stream(s) will now appear in your data list.
