Coastal Flooding
Coastal flooding is flooding driven by seawater pushing onto land, most commonly caused by storm surge during a typhoon's passage near or over the coastline.
Flood Advisory
A flood advisory is a lower-level notice than a flood warning, indicating that flooding is possible but not yet occurring or imminent.
Flood Depth
Flood depth is the measured or estimated height of floodwater above ground level, used to assess severity and guide evacuation decisions.
Flood Risk
Flood risk describes the likelihood and potential severity of flooding in a given area, based on factors like elevation, proximity to rivers or coastline, and historical flooding patterns.
Flood Warning
A flood warning is an official notice indicating that flooding is occurring or is imminent in a specific area, issued by PAGASA or local disaster offices based on river levels or rainfall forecasts.
Floodplain
A floodplain is the low-lying land bordering a river that is naturally prone to flooding when the river exceeds its capacity.
Inundation
Inundation is the covering of normally dry land with water, the general term used for flooding from any source, whether river, rain, or storm surge.
River Flood
A river flood occurs when sustained or heavy rainfall causes a river to exceed its banks, typically developing more slowly than a flash flood but affecting a wider area for a longer duration.
