Abstract
This research aims to investigate the effect which big coastal facilities exert on coastal erosion due to waves in Khlong Wan Coast and examine some measures. Field surveys and a long-term simulation with the one-line numerical model indicated that the blockage of silt-and-sand supply from the northeast side of the coast by a big groin and the blockage of the supply from the southwest side by a huge detached breakwater has caused coastal erosion. Moreover, because the prediction using the one-line model showed that the beach in the southwest side of an old fishing port will become the most dangerous area, some measures for the coastal protection were proposed. Then, examinations on topographical changes of the beach, wave overtopping rates, etc. elucidate that sand nourishment is the most effective measure.
