-The design of bypass tunnels depends on catchment characteristics like topography, geology, hydrology and the reservoir's shape and size (Tiger et al. 2011, Hauer et al. 2018, Boes et al. 2019).  They function well in small reservoir with steep slopes as the gradient of the diversion channel needs to be sufficiently large to insure the transport of sediments. The use of bypass tunnels with intake located at the reservoir head is a measure that does not interfere with hydropower operations since it does not require a drawdown of the reservoir. In contrast, if the tunnel intake is located in the reservoir, a partial reservoir drawdown is required to transport incoming sediment to the tunnel guiding structure (Fig. 1). In addition, sediment routing through bypass tunnels induces less impacts on the downstream ecosystems than reservoir flushing or sluicing. However, bypass structures are not well adapted to flood control reservoirs as they undercut the main role of these reservoirs (Kondolf et al. 2014).

-The main challenge of bypass tunnels is abrasion. Entrance of sediments degrades the inlets of the tunnels and can induce deep abrasion of the material. High strength concrete is recommended for the construction of the tunnels.
+The main challenge of bypass tunnels is abrasion. The intense bed load transport degrades the invert of the tunnels and can induce deep abrasion of the material. High-strength concrete or hard natural stone materials such a sgranit are recommended for the invert protection of the sediment bypass tunnels (Müller-Hagmann et al., 2020).
