The example given in "Annex A - Case Study" of the Deltares report 1200503-001-GEO-0004 "Concept Technisch Rapport Voorland Zettingsvloeiing" of G.A. van den Ham & Co is used.
In this example, both global and detailed checks are completed on the basis of a (fictitious) dike section, which with regard to geometry and soil structure is typical of the Southwest Delta.
The dike has a height of NAP+5 m and , a crest width of 3 m and a slope of 1:3.
The foreshore begins to imaginary toe of the dike at an elevation of NAP and is 60 m wide. The toe of the trench is NAP-15 m and has a slope of 1:6. The dike section is 800 m long. The phreatic level is at NAP-2 m.
The soil profile is as follows:
...
The details of the calculation can be found in annexe annex A of the report. The main results are given in the table below. The global check fails but the detailed check passes.

Comparison with SLIQ2D (Dos and Windows) - One fully saturated layer with variable slope angle
Description
The benchmarks in this paragraph are intended to verify the advanced method by comparing D-FLOW SLIDE results with those from the older program SLIQ-2D, using both DOS and Windows versions of this program.
Because of the limitations in the DOS version of SLIQ2D, only one fully saturated layer is inputted. The geometry and the material properties for each cases are given in the table below.
The original slope angle is 1:1.25 and is set to "variable" so that the program will search (for each point) for the most unfavorable slope.
