Coastal erosion is an island-wide problem in Taiwan. Based on the most recent survey, about 80% of the island's sandy coastline had suffered from erosion over the past few decades. Historically, with the specific tectonic environment and rapid uplifting rate in Taiwan, lots of sediment had been yielded and transported to the coastal area that resulted in an advancing shoreline. During the recent processes that changing Taiwan economically from a developing country to a developed one, a lot of human intervention had been made along the island coast, and it is considered to be the major factors on recent coastal erosion.Even actions intended to save the coast, such as building of stabilization structures may inadvertently increase erosion. In this paper, some intervention examples are chosen to address how human-induced change made the profound impact on coastal erosion in Taiwan. AU the information is to provide a better understanding of the coastal processes, and a better response to the erosion problem.
