Description

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

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.
