This section describes a number of benchmarks for which an exact analytical solution can be found in the literature.

Study Case described in "Technisch Rapport Voorland Zettingsvloeiing".

Description

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 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.
The foreshore begins to imaginary toe of the dike at an elevation of NAP and is 60m wide. The toe of the trench is NAP-15, 0 m and has a slope of 1:6. The dike section is 800m long.
The soil profile is as follows:

• from NAP +3.5 m to NAP +1 m: peat
• from NAP +1 m to NAP -5 m: silty clay
• from NAP -5 m to NAP -18 m: moderately to loosely compacted sand (Calais)
  *from NAP -18 m to NAP -30 m: densely compacted sand
