D-Flow Slide needs extra input parameters compared to the Study Case:
- Ψ5m = -0.03 for sand layers and Ψ5m = -0.06 for other layers (used in Global step 1)
- Ψ5m = -0.03 (used in Global step 5 and Detailed checks)
- D50 = 180 μm and D15 = 130 μm for Calais sand
- D50 = 160 μm and D15 = 110 μm for Compacted sand
- Cohesive layers factor = 0.2
- Migration velocity = 0.0001 mm/year
