A shoreline erosion control device having a frame fixed to the ground along the shoreline of a body of water and in the path of the wave action on the body of water. A plurality of screened louvers are pivotally secured to the frame and are adapted to pivot to the open position on the side of the frame facing away from the body of water during movement of a wave therepast. A return of the water in the wave toward the body of water will effect a closing of the screened louver and any sand that will be contained in the returning water will be strained by the screened louvers. The slightly restrictive openings in the mesh will slow the water velocity and allow the large grains of sand and soil to fall on the landward side of the screened louvers and due to the slowing of the wave action the sand particles that pass through the screen to fall on the seaward side of the device thus creating a gentle slope to the bottom.
