Add Water by Location
The Add Water by Location option allows you to model the groundwater pore pressure distribution by defining XYZ coordinates to generate a surface that represents the water table or an actual Piezometric surface obtained from piezometer measurements.
Project Settings
You must first set the Groundwater Method = Phreatic Surfaces in the Groundwater Tab of the Project Settings dialog.
Add Water by Location
To add water by location to your model:
- Select the Groundwater
workflow tab.
- Select Add Water by Location
option from the toolbar or the Groundwater menu.
- In the Water by Location dialog, you can change the name and colour of your generated water surface.
- To create a new Water Surface, select the Add
button, or choose an existing water surface from the list at the left of the dialog to edit its properties.
- Select the desired Surface Reconstruction parameters used to generate the surface. Review the Surface Reconstruction page in the theory section for more detail. The user may use any of the following Interpolation methods:
- Inverse Distance
- Thin-Plate Spline
- Chugh
- Local Thin-Plate Spline
- Linear/Triangulation
- Gaussian
- Multi Quadratic
- Polyharmonic Spline
- Compactly Supported
- Select the Extrapolate checkbox to extend the generated surface to the limits of your model in the x and y direction. This will ensure that the water surface affects all the elements without explicitly defining location points at the edges of your model in the XY plane.
- Select Ok to generate the water surface(s).
- Review the surfaces by selecting the water surface entity in the Visibility pane. The water surfaces are hidden by default until you assign them to a material (see next step).
- To use a water surface in the calculations, you must assign it to the material properties using the Define Hydraulic Properties
option.
