Non-suitable area detection for ports and harbour construction alongside coastal water using remote sensing approach

The intertidal zone, being an interface between terrestrial and marine environments, is very susceptible to environmental changes like sea level rise, coastal erosion, and human activities. They have direct repercussions on biodiversity, marine ecosystems, and socio-economic activities, mainly for the locals who depend on tourism and fishing. Through an understanding of the spatial and temporal intertidal zone variations, this study also hopes to enlighten us about the degree of coastal transformation with time. The aim of this study is to identify changes in the intertidal zone that is unsuitable to be constrycted as port or harbour using satellite remote sensing data between 2016 and 2023 in the Perlis coastal area.
