- Riverine Flood: The overflowing of a river, creek, lake or dam beyond its normal banks, causing inundation of surrounding land. This is what most people think of as "flooding" and is the category most commonly excluded or restricted in farm policies.
- Flash Flood: Rapid onset flooding caused by intense rainfall, often in areas not adjacent to watercourses. Some insurers treat flash flood differently to riverine flood in their policy wording.
- Stormwater Runoff: Water damage caused by surface runoff from heavy rain, including overland flow that enters buildings. Most farm policies cover stormwater damage as part of storm cover, even when flood is excluded.
- Actions of the Sea: Coastal inundation from storm surge or tidal events. This is typically excluded from farm policies.
