- for the distribution of the stochastic parameters of the Detailed check (LogNormal instead of Deterministic/Normal)
- for the channel slope which is 1 : 7.1 instead of 1 : 6.
- for the grain diameters:
- for Calais sand : D50 = 230 μm (instead of 180) and D15 = 130 μm (unchanged)
- for Compacted sand : D50 = 210 μm (instead of 160) and D15 = 110 μm (unchanged)
For case H, the same input as benchmark 1-1 (see group 1) is used except:
- for the distribution of the stochastic parameters of the Detailed check (LogNormal instead of Deterministic/Normal)
- for the state parameter which is equal to -0.06 instead of -0.03
- for the diameters D50 and D15 which are equal to 250 μm and 150 μm resp. for sand layers.
- for the Detailed check, the required probability of failure is 1 per 40000 years instead of 1 per 4000 years and the migration velocity is 0.5m/year instead of 10 mm /year.

For each cases, the Global and Detailed checks are worked out in an Excel spreadsheet.
