In order to understand the overtopping effect of guiding arc parapet,wave flume experiments were applied.The influences for the overtopping discharge caused by the relative height of parapet,the relative distance from water level to the toe of wall and the arc shape were analyzed.Then the formula for calculating the overtopping discharge of guiding arc parapet wall was developed on the basis of the formula for vertical parapet wall.The results show that the overtopping discharge will decrease with the increase of relative height of parapet and relative distance from the water level to the toe of wall.But the overtopping amount for single arc parapet is obviously less than double arc parapet.The results obtained from the proposed formula are well agreeable with actual data.
