Pluvial (Surface water Flood)
A pluvial, or surface water flood, is caused when heavy rainfall creates a flood event independent of an overflowing water body. One of the most common misconceptions about flood risk is that one must be located near a body of water to be at risk. Pluvial flooding debunks that myth, as it can happen in any urban area — even higher elevation areas that lie above coastal and river floodplains.
There are three common types of pluvial flooding:
- Intense rain saturates the drainage system. The system becomes overwhelmed and water flows out into streets and nearby Properties.
- Run-off from hard standings/ such as / Roads/lanes where the gullies cannot cope with the heavy rain fall.
- Run-off or flowing water from rain falling on hillsides that are unable to absorb the water.
