Hazard degree assessment of coastal erosion at Tianlongsi adjacent sandy coast

摘要

In order to respond effectively to the needs of coastal erosion disaster prevention and mitigation and emergency management, shoreline positions prediction model were established by using digital shoreline analysis system based on 2011 to 2014 0.5 m high-resolution remote sensing data and geographic information system platform, and validated the model by using the field measurement shoreline data at Tianlongsi adjacent sandy coast, Suizhong, China. The results showed that there are a better coincident between the model results and the field measurement results, meanwhile, shoreline erosion range in future period without outside interference conditions was predicted according to the model, which would be provided a technical support for carrying out the coastal erosion disasters comprehensive management and rational planning of industrial layout along the coast.
