STABILITY ANALYSIS OF RUBBLE-MOUND BREAKWATERS UNDER TSUNAMI FIRST IMPACT AND OVERFLOW

摘要

Tsunamis are relatively infrequent but very destructive phenomena that can cause devastating consequences on coastal areas. In view of recent tragic episodes, the scientific community is strengthening their efforts to develop strategies to mitigate the risk of tsunami consequences, specially focused on the potentially affected areas. One of the strategies in this direction is the design and construction of more efficient coastal structures. In this way, in the frame of the EU FP7 project ASTARTE physical experiments on rubble-mound breakwaters (RMB) under tsunami wave attack have been carried out in the IH Cantabria facilities in Santander, Spain. These experiments focused on gaining a better understanding of tsunami impacts on this kind of structures. Improving the knowledge about their stability and hydrodynamics will contribute to a better design of coastal protection marine structures.
