Sea level rise simulation at Major Towns of East Coast of Peninsular Malaysia

Global warming is caused by greenhouse gases resulting from natural causes and human activities. This event causes the sea level rise (SLR). The effects of SLR are the submerging of an area, saltwater intrusion, erosion, and the destruction of infrastructure and marine ecosystems. The objectives of...
