These areas are immediately flooded during heavy rains of several hours; include landforms of topographic lows such as active river channels, abandoned river channels and area along river banks; also prone to flashfloods. High flood susceptibility Purok X Areas likely to experience flood heights of greater than 1 up to (Maguinda)# 2 meters and/or flood duration of more than 3 days. These areas are immediately flooded during heavy rains of several hours; include landforms of topographic lows such as active river channels, abandoned river channels and area along river banks; also prone to flashfloods. Moderate flood susceptibility Areas likely to experience flood heights of greater than 0.5m up to 1 meter and/or flood duration of 1 to 3 days. These San Juan Elementary School (Florida)n areas are subject to widespread inundation during prolonged and extensive heavy rainfall or extreme weather condition. Fluvial terraces, alluvial fans, and infilled valleys are areas moderately subjected to flooding. 8°48'0"N 8°48'0"N 125°36'0"E 125°37'0"E 125°38'0"E 125°39'0"E Low flood susceptibility Areas likely to experience flood heights of 0.5 meter or less and/or flood duration of less than 1 day. These areas include Data Sources : Coordinate System : low hills and gentle slopes. They also have sparse to MGB Geohazard Assessment Team moderate drainage density.
