Types of flooding

Storms and heavy rain can lead to river and sea flooding. Large-scale flooding like this can cause a danger to life and to property.

Flooding on roads can be caused by overflowing rivers, blocked highway drains and grates, or burst water or sewage pipes. 

Persistent or heavy rain can cause the ground to become saturated. This often means water cannot drain away quickly enough, leading to groundwater or surface water flooding.

Surface water flooding can also happen when underground rivers and lakes overflow, causing the water to rise above the surface. 

This may continue for weeks after the rain has stopped. 

Persistent or heavy rain can overwhelm drainage systems, causing water to accumulate on the surface. This often leads to surface wate flooding, especially in urban areas where impermeable surfaces prevent water from soaking into the ground.

Surface water flooding can also occur when rivers and streams overflow, spreading water across roads and properties. 

This type of flooding can persist for days or even weeks, depending on the severity of the rainfall and the capacity of drainage systems.

Sewer flooding can have several different causes and can be a symptom or consequence of other flooding that happened first.
