Experimental study on bed-material transport over entrance sills at longitudinal training walls

Bed-material transport over entrance sills at longitudinal training walls

Groynes have been replaced by longitudinal training walls in an 11-km long pilot project to optimize training of the river Waal in the Netherlands. These train­ ing walls improve navigability, reduce flood levels, create a sheltered second channel with more favourable ecological conditions, and decrease the erosive action on the river bed that...
