Abstract
This study carried out several laboratory tests such as water tank settlement test and two-dimensional water flow test to investigate settlement and scour characteristics of a square-shaped hybrid reef which was reinforced with geogrid. In addition, numerical analysis was also performed to find out scour characteristics of the square-shaped hybrid reef with different placement types (type A; straight placement type, type B; zigzag placement type). Laboratory test results indicated that settlement and scouring depth significantly reduced in hybrid reefs reinforced with geogrid, compared with those without reinforcement. Two-dimentional water flow tests and numerical test results also showed that scouring depth and flow velocity of placement type A more decreased than those of type B.
