ABSTRACT
ABSTRACT: Downstream slopes of rockfill dams in Norway are protected with placed riprap against considerable leakages through the dam or overtopping. For this purpose, oblong stones are placed one by one in an interlocking pattern. Six large-scale field tests were run to increase the knowledge about placed riprap on steep slopes. The 3.5 m high and 10 m wide test dams withstood unit discharges of over 8 m3/s/m. There is a presentation of the facilities, test set-up and measuring equipment with focus on practical issues and challenges connected with large-scale tests in order to share useful experience about such uncommon experiments.
