Description
Erosion and sedimentation of materials (gauge and bentonite) in fractures in the rock by groundwater flowing in these fractures.

Geosphere
Handling
Explanation of how the FEP is treated
Excavation/operation: Neglected because of too low flow rates in non-grouted fractures.
Temperate: Neglected because expected hydraulic gradients and shear stresses are too low to cause significant erosion.
Periglacial: Neglected because expected hydraulic gradients and shear stresses are too low to cause significant erosion.
Glacial: Neglected because expected hydraulic gradients and shear stresses are too low to cause significant erosion.
Earthquakes: Not relevant.
