A series of tests of wedge-shaped blocks intended for armoring embankment dams and levees was carried out in a new experimental facility (‘Hydraulic Experimentation Facility—Luis Ruano’) under quasi-prototype conditions. This unique facility is located in the canal leading to the Laverné reservoir (Zaragoza, Spain) with a maximum vertical drop of 7 m and discharge up to 9 m3 s−1. The aim was to conduct experimental research on technologies to protect embankment dams and dikes against overflowing erosion under quasi-prototype conditions. The results of the tests demonstrate the ability of the WSBs to withstand high unit discharges under extremely negative conditions at the upstream and downstream ends of the armoring. The tests also helped to identify potential failure modes for the armoring blocks.
