Rock Armor Stability
The performance of coastal structures is usually being evaluated by performing model tests with a constant still water level. However, in reality water levels vary during a storm due to the presence of storm surge or a tide. Here, tests have been performed with rock armoured slopes with wave loading under various water levels, including tests with water levels that continuously vary during a single experiment. The armour stability has been compared to results from tests with constant still water levels. The performed tests show the importance of water level variations on the response of rock armour.
