Summary

Description
English: Wear can be seen on granite pavers in the Pfaffensprung tunnel where the movement of particles through water has caused a groove to form in the material. While granite is one of the most durable materials to be used in this role, it is not immune to the forces exerted by flowing sediment particles. Careful repairs and maintenance are required to keep the tunnel fully operational and effective. (Photo by Jesse Brown, USACE – Huntington District)
