High flood susceptibility Areas likely to experience flood heights of greater than 1 up to 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 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°57'0"N 8°57'0"N 125°15'0"E 125°16'0"E 125°17'0"E 125°18'0"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.
