Remote sensing and GIS-based assessment of coastal vulnerability of Bolinao, Pangasinan to sea level rise

Recent studies have classsified the Philippines as one of the many Asian countries that are highly vulnerable to the major effects of climate change. A number of investigations using satellite altimetry data verified the varying trends in sea level across the South China Sea, which is one of the lar...
