WAVE TRANSMISSION, REFLECTION AND ENERGY LOSS OF AN ALTERNATIVELY SUBMERGED GEOTUBE BREAKWATER SUBJECTED TO REGULAR WAVES

Over the years, there are quite a number of research and studies has been done towards
the cause and effect of shoreline erosion. Some researchers used hard engineering
method (conventional) and others followed the soft engineering method (geosynthetic).
However not every research that has been conducted leads to success as there are still
a lot of gaps that needs to be filled in their research. This study will be conducted to test
the effect of wave transmission, reflection and energy loss of an alternatively
submerged geotextile tube (geotube) that act as semicircular breakwater when subjected
to regular waves. The water when subjected to regular waves, has few hydraulic
characteristics such as wave steepness Hi/L, relative wave height Hi/d, and relative
submergence, d’/Hi that will be determined in order to achieve the aim at the end of the
experiment. This study focus mainly on testing the physical model of geotube against
the wave parameters that was mentioned above.
