Coastline Change of Sanhe Island in Tianjin Using Remote Sensing Techniques

Coastline change is a result of natural process and anthropogenic interference, such as sea level change, storm surge, currents, dredging, river damming, and land reclamation (Jia et al., 2016; Xu, 2018; Zhu et al., 2017; Zhu et al., 2018). Monitoring coastline change helps us to understand the coastal responses to these factors. Previous developments, such as in-situ observation, numerical investigation and remote sensing, have enabled researchers to track the coastal erosion and coastline change (Bay et al., 2012; Stutz and Pilkey, 2011; Zhu et al., 2017). However, study on coastline change of island is relatively insufficient. *
