Entering Downhole Water Level Data

The Borehole Manager’s Water Levels table is used to enter one or more dates, depths, and optional text for observed water level(s) in the boreholes. These can be displayed as bars in strip logs and log sections, and modeled as surfaces for display in profiles, sections, fence diagrams, and 3D blocks.

Multiple, distinct, aquifers can be defined.  The Water Levels data table links to the Aquifer Types Table where the aquifer names are defined.

Accessing the Water Levels Table

1. Access the Borehole Manager
2. Create a new project as necessary.
3. Create a new well if necessary, or click on the existing well to be edited.
4. Click on the Water Levels table for the well.

Water Level Fields

These instructions are for hand-entering the data; please see the links at the end of this topic for other options.

• Aquifer Name: Double-click in this cell and choose the Aquifer name from the Aquifer Types Table.  Or, you can single-click in this cell, click the small down arrow, and choose the name from the drop-down list.  
  • If the aquifer name is not listed, you'll need to add it to the current Aquifer Types Table.  See the Aquifer Types Table section for more information. 
    
    
• Date: Here you enter the date on which the measurement was taken - double-click in the cell and choose a date.  On logs, the date field can be displayed as a text label.  For interpolated models and diagrams, RockWorks will use the Date field to match like measurements between wells. The date and time formats will automatically adjust to U.S. or European formats based on the Windows Regional Settings. 
  
  
• Depth to Top: Type in the measured depth to the top of the water level.
  ! The depth units must be the same as the Vertical units you defined for the project (and which are displayed on the Location table). For example, if the elevation and TD for the hole are shown there in feet, then the depth listings here must be in feet as well.
  ! The depth values must be positive. 
  
  
• Depth to Base: Type in the measured depth to the base of the water interval. If you don't have base depths (or if you simply wish to display the water level model as a surface of little or no thickness), set the Base depth to slightly greater than or equal to the Top depth.
  
  
• From Elevation / From Collar Elevation: Use this button at the top of the table to define for this borehole which datum your depths were measured from.
  • Choose Measured from Elevation if the depths were measured from the ground elevation (entered as the "Z (Elevation)" field in the Collar Coordinates tab). This is the default setting.
  • Choose Measured from Collar Elevation if the depths were measured from the collar elevation (entered as the "Collar Elevation" field in the Collar Coordinates tab).

• Repeat this process for additional aquifers and/or water level measurement dates.
