- Analytical - Wave penetration is computed on a grid within the harbour basin and is based on Cornu spiral waves propagating into the harbour basin. Note that this does not take into account processes such as reflection and diffraction.
- Diffrac2DH - Wave penetration is computed using the numerical Diffrac2DH schemisation (solving the Helmholtz equation). This method takes reflection and diffraction into account.

Tool limitations
The following processes are not included in the tool: wave directional spreading, bed level changes throughout the harbor, wave reflection (in case of using the analytical method) or varying reflection values (in case of Diffrac2DH), etc. Results of the wave penetration tool should therefore be interpreted with a considerable range of uncertainty.
