| Summary: | Resonance phenomenon at the extreme scale can damage the environment.
This phenomenon may occur due to the absence of breakwater construction to
dispel the coming wave currents. Therefore, we will examine the effect of porous
breakwater on resonance phenomenon. There are three observed cases, consists of
the placement of: one block rectangular submerged porous breakwater, two block
rectangular submerged porous breakwater, and combination of one block
rectangular submerged porous breakwater along with one vertical rectangular
porous breakwater. Analytically, we will find the basin’s natural period value
using a modified shallow water equation model for the two-layer case. The
basin’s natural period value is a parameter needed to observe the resonance
phenomenon. Afterwards, we will do several simulations using numerical scheme
which is derived from the finite volume method on a staggered grid. Based on the
simulation, we will define the porous breakwater’s dumping coefficient needed to
stop the resonance phenomenon. |
