Monitoring Beach Erosion Control Alternatives: Southern California Examples

Survey monitoring methods are described which can be generally used to quantify the effectiveness of erosion control devices on sandy coastlines. Monitoring results of the Longard Tube installation at Del Mar, California are reported as an example. We conclude that due to high sand levels and low storm activity the tube has had insufficient interaction to assess its effectiveness. The baseline sand level data available on Del Mar beach illustrate the importance of detailed knowledge of the region of the erosion control device being assessed.
