초록

The current study reviews the formula used to calculate the stability of an
artificial reef in the breaking wave zone of coastal waters. A comparison was carried out
between the existing formula and a new formula that takes into account the water
particle velocity in the breaking wave zone. Water particle velocity was analyzed using
the Fluent (CADMAS-SURF) software program. The new formula took into various
factors, including the difference in the drag coefficient due to the direction of the
current and the ratio of distance between two reefs. The drag coefficient of the artificial
reef due to the direction of the current was 0.84 when the distance ratio was 0.5. When
the artificial reef was placed at 45 degree angle to the current, the product of the drag
coefficient and the project area were 40 to 46 % greater than when the reef was placed
at 90 degree angle. Our results regarding the stability of an artificial reef indicate that
the new formula provides the designers of artificial reefs with a more rational and
economic design rationale rather than the existing formula.
