Flood

Very high flood susceptibility Areas likely to experience flood heights of greater than 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.

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

R. Castillo Primary School Areas likely to experience flood heights of greater than 0.5m up to (Mone) nPurok III Baguis 1 meter and/or flood duration of 1 to 3 days. These (Mone)# areas are subject to widespread inundation during prolonged and extensive heavy rainfall or extreme weather condition.
