The frame "Water" serves to specify the ground water table (GWT). A combo list "Type of water" contains the following items:
- No water - no water specified
- Water specified by points - the GWT points are defined in the table in the same way as when defining terrain points. This approach is particularly suitable if having a horizontal water table - then it is sufficient to define only one point of a given coordinate Z and the program automatically generates a horizontal line representing the GWT.
- Water specified in boreholes - Ground water is defined within boreholes. A particular depth of GWT measured from terrain surface is specified. This approach is suitable when boreholes with measured depths of GWT are available.
