Scenario Analysis on the Susceptibility of Cantilan DepEd Elementary Schools to Storm Surge

Abstract

This study used geographic information systems (GIS) and remote sensing as a tool in simulating the storm surge in Cantilan, Surigao del Sur. Storm surge shapefile were downloaded at the website of Nationwide Operational Assessment of Hazards (Project NOAH) which is the flagship disaster mitigation program of the Department of Science and Technology (DOST) of the Philippine government.  Digital elevation mapping, image processing, and overlaying of schools geographic coordinates were conducted in QGIS 3.16 Software. Results of the study revealed that at SSA 1 or 2 meters height of possible storm surge, five (5) elementary schools of Cantilan are susceptible. At SSA 2, with a height of 3 meters, there are four (4) schools susceptible at 3 meters height. When it comes to SSA 3, ten (10) schools are susceptible to 4 meters height of water level. Moreover, all the elementary schools located at the coastal area are susceptible to storm surge SSA 4 with a height of 5 meters..
