Flash floods occur due to varying meteorological and hydrological conditions of the river basin, and changes in climate and land use. These variables make forecasting and detecting flash floods challenging, especially since ares with land use and land cover (LULC) characteristics and vulnerable to heavy flash flood. In Cagayan de Oro, recent calamities brought by extreme rain events affected 2 barangays [villages] Cugman and Gusa -within the Bigaan River Basin. This research aimed to investigate the Flash Flood Guidance system as an early flood warning mechanism, and suggested areas for reforestation and conservation through GIS [Geographic Information System] mapping and land use characteristics. Techniques in geospatial technology, such as remote sensing and geographic information system, were widely used. With field validation, these technologies analyzed the LULC characteristics of the area. Satellite imagery from 2015 obtained through the latest Landsat satellite mission were used to classify the different LULC of the basin. Results determined the flash flood guidance system for the river basin and the areas which needed reforestation and conservation.
