Due to various changes in the safety assessment for piping in recent years, such as taking into account the length-effect, the transition to the flood probability approach, the removal of Bligh's rule, and adjustments in the Sellmeijer model, many more dikes do not meet the requirements. These developments have created a need for more advanced piping calculations.
To be able to assess such complex situations, D-Geo Flow has been developed. D-Geo Flow includes a Finite Element piping analysis, based on the Sellmeijer model, to be able to assess whether piping can occur given a specific water level progression.
In D-Geo Flow, it is possible to perform 2D groundwater flow calculations with layered, heterogeneous soil structure.
D-Geo Flow includes the following features:
- Calculation of 2D groundwater flow,
- The (modified) Sellmeijer rule for predicting the occurrence of piping,
- Ability to set up complex, multi-layered soil schematizations,
- Graphical and numerical presentation of groundwater calculation results and pipe development.
How can I get D-Geo Flow?
