Abstract :
Submerged breakwaters are a special type of breakwater associated with low
wave reflection. They can also save large quantities of engineering resources
from the view of economics. Although there have been previous investigations
on the interaction between waves and rubble mound low-crested breakwaters,
performance of impermeable submerged breakwater is somehow different
from rubble mound structures. Thus, the accurate estimation of reflection and
transmission coefficients is essential in designing of this kind of structures in
near shore zone. In this paper, performance of impermeable trapezoidal
submerged breakwater was investigated experimentally using regular waves.
In the experimental plan, for three submergence depths of breakwaters
different wave groups were used to measure transmission and reflection
coefficients. Based on the test results, empirical expressions were formulated
to describe the transmission and reflection coefficients for solid submerged
breakwater under regular group waves.
