This section uses tests performed by hand or by means of an Excel spreadsheet.
3.1 Test of all possible trajectories of the Global check and the Overall result
...
For case F, 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 channel slope which is 1 : 2 instead of 1 : 6.
For case G, 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.
Benchmarks results
For each cases, the Global and Detailed checks are worked out in an Excel spreadsheet.
