Flood Path Routing In Brgy. Calumpang, General Santos City Using Geographical Information System

     This study was conducted to generate a map that determines the flood routes of barangay Calumpang, General Santos City, as a fundamental data for future related projects and to have a field verification of the recent condition of the flood path as cited during field survey.

     The study site-Brgy. Calumpang was surveyed through ocular inspection to gather point coordinates. The generated points were then imported into the GIS database. The saved file was then converted into a shape file using the digitizing tools in the QGIS software environment. The generated layer was then overlaid into the acquired flood hazard map and topographic map to finally generate the flood path map.

     The resulting map shows that more paths occur in areas which are highly populated and are naturally low-lying. Also, those areas are in medium risk of flooding which poses a major threat on the transportation, health and wellness, and also to the existing structures (Liongson, 2004).

     Hence, it is recommended to take every step of every process as less error as possible and further conduct this study by getting sample on various runoff and replicate the procedure in all barangays of the city.
