WUFI 2D: wall in a ground depression – boundary conditions for surface water
Posted: Tue Nov 10, 2026 5:57 pm -1100
Hello,
Can the attached case be simulated in WUFI 2D? A 50 cm masonry wall on a concrete foundation with an interior slab. The surrounding ground has risen by approx. 100-150 cm, so the wall now stands in a pit (Example 1: section sketch, example 2: site photo).
I want to understand which of these causes the moisture problem, or their combined effect:
1. Groundwater flowing toward the wall, foundation and slab
2. Surface runoff collecting in the pit
3. Reduced drying due to the pit microclimate (low wind, high RH, less sun)
Questions:
1. How do I model soil, foundation, wall and slab in one 2D section?
2. How do I represent each effect (groundwater, runoff, reduced drying) so I can compare them?
3. Are there example files for below-grade walls?
Best regards,
Hüsna
