Understanding Flood 

River Flooding

River flooding, or fluvial flooding, is a very common type of flooding in the UK. This is where a river’s flow will exceed the bank sides and cause damage or obstruction to a nearby area. Homes and businesses located near streams and rivers should always check their flood risk, to see if they should be worried about river flooding.

Tidal Flooding 

Coastal flooding is a type of flooding that affects communities situated close to the sea. With high tides, stormy weather, and climate change all contributing to an increased risk of coastal flooding, this is a major hazard for many areas of the UK. Seawater over topping coastal defences can cause significant damage and disruption to communities, often requiring retreat further inland. With the added problem of salt in the seawater damaging buildings, coastal flooding is a serious issue and should be addressed with appropriate flood protection.

Surface Water Flooding

Surface water (also known as pluvial) flooding can affect people all around the country. Even if you are not situated near to a rive or the sea, you may still be at risk of this type of flooding. Surface water flooding occurs after periods of heavy rainfall where excess water cannot drain away. This may be due to a range of reasons including blocked drains or even rainwater running off roads. This water will then collect in an area it cannot drain away from and can cause serious damage. Surface water flood maps are currently available in the UK, but as areas change and develop, this may change where water could collect. Just because your home or business has not flooded before, does not mean that it may not flood in the future.

Groundwater Flood

Groundwater flooding can affect homes and businesses in the UK although this is not the most common type of flooding. For groundwater flooding to occur, the water table in an area must rise as a result of increased rain. When this water table rises up through a slope, there may be a point at which the water table is above the ground level. If this happens, the water will flow over the surface as it cannot seep into the ground – this is groundwater flooding. Unlike other types of flooding, groundwater flooding may require you to consider measures to protect your home that will prevent water from rising up from below your building – such as a floor membrane.

Sewer Flooding

Sewage flooding rarely affects homes and gardens in the United Kingdom. Sewage flooding however is extremely unpleasant and can be a dangerous type of flood in the UK due to the high levels of bacteria that can spread. The risk of sewage flooding is low in the UK due to both private companys, and local councils putting flood prevention systems in place.

The most common cause of sewage flooding is a blockage in the sewage pipe. It is crucial if you notice sewage flooding, to contact your council and a professional clean-up company should be organised to ensure minimal health risks occur.

Run Off Water Flooding 

Surface run off is the water flow that occurs when soil is infiltrated to full capacity and excess water from rain, melt water or other sources flows over the land.
