摘要

Cyclone is the mostGeospatial technology hazardous phenomenon all over the globe and its effect can be found in the coastal regions of the world. CycloneCyclone causes floodingFlooding, storm surge, landslidesLandslides, heavy rain, and huge property and environmental damage. The intensity and number of cyclonesCyclone are triggering due to climate change and its relative impact over ocean and land surface temperature in recent decade. The purpose of the study is to assess cycloneCyclone induced hazard. The study adopts Geographic Information Systems (GIS)GIS-based Analytical Hierarchy Weightage matrix of Bhadrak district and proposes strategic measures for sustainable cycloneCyclone disaster managementDisaster management of that area. Land use/land cover (LULC), geomorphology, lithology, elevation, slope, drainage density, topographic wetness index (TWI), and rainfall are considered important cycloneCyclone hazard factors.
