Reshape of Wave Break Structure under Irregular Wave Attack

Alireza Bakhtiari, and Manoochehr Fathi Moghadam

Experiments are conducted to investigate effects of irregular wave parameters on reshaping of seawall. Tests run in several water level conditions. The experiments and physical modeling are conducted in a combined flume at the Soil Conservation and Watershed Management Research Institute (SCWMRI). The energy spectrum of the applied waves is JONSWAP. The material of armour layer have been constructed with the scale of 1:25 model and grading class of D85/D15=1.82. Adequate number of waves was subjected to the structure to get enough data for analysis. The results showed that damages to the structure reduced by 85% as wave steepness increased by 82%. Also, damages to the structure reduced by 83% as wave height increased by %57
