Structural geology and topographic mapping of Kelantan river basin using PALSAR-2 remote sensing data for high risk area delination

Identification of high potential risk and susceptible zones for natural hazards of geological origin is one of the most important applications of advanced remote sensing technology in tropical environments. Yearly, several landslides occur during heavy monsoon rainfall in Kelantan river basin, Penin...
