An Analysis of Shoreline Changes Using Combined Multitemporal Remote Sensing and Digital Evaluation Model

摘要: Cua Dai estuary belonged to Quang Nam province is considered be one of the localities Vietnam having a complex erosion and accretion process. In this area, sandbars are recently observed with lots arguments about causes regimes formation. This could very likely result not reliable source information on shoreline evolution lack historical monitoring data. Accurately identification positions over given period time key quantitatively accurately assessing beach accretion. The study therefore propose an innovative method for analysis coastal in estuary. proposed technology multitemporal remote sensing digital evaluation model tidal correction used analyse changes estimate rate An empirical formula is, especially, exposed fully interpret multiple scales based limitation satellite images during 1965 2018. results show that there significant difference shift between corrections non-corrections tidal. Erosion process tends recorded cape located ward, especially Luong Duy Hai commune length 1050 m. Furthermore, it much stronger north side compared south
