It results that SBTs are an effective measure to reduce the sedimentation of dam reservoirs, particularly of type (A) with intake at the reservoir head. The hydroabrasive wear of tunnel inverts is significant and has to be mitigated by using adequate invert liners. The invert abrasion can be estimated based on an abrasion model where a correct input value of the bed material resistance coefficient is paramount to limit model uncertainties. Based on abrasion measurements at prototype SBTs typical values of the material resistance coefficient are recommended for high-strength concrete, natural stones and steel liners. The field experiences gathered so far and the comparison of various invert materials suggest granite pavers as a promising lining material for severe abrasion conditions.}, language = {en} } @inproceedings{AuelTheneMuellerHagemannetal.2017, author = {Auel, C. and Thene, J.R. and M{\"u}ller-Hagemann, M. and Albaryak, I. and Boes, R.M.}, title = {Abrasion prediction at Mud Mountain sediment bypass tunnel}, series = {Proc. 2nd Int.
