In this study, we analyzed the flow characteristics in the wide-crested side weir of trapezoidal section by using a three dimensional numerical stimulation. From this study, as the Froude number increases in the main channel, the overflow discharge ratio and the discharge coefficient of lateral overflow tend to decrease. And it was also found that the increase of the lateral overflow reduces the channel discharge area in the downstream, and the size of recirculating zone is increasing in the opposite side of side weir. The stream-wise water surface on the side where the side weir is installed falls down rapidly in the weir starting point, gradually ascending, and rapidly rising at the end point. The reason why the water surface rapidly rises at the weir end point is because the weir end point hinders the flow.
