Coastal flooding

The force of the sea has shaped our coastline into what it is today. Scotland has over 13000km of coastline, which includes cliffs, dunes, sea lochs and rocky shorelines. Over the years, coastal settlements have developed around our ports and harbours to support industries such as fishing, agriculture, oil and gas.

Low-lying communities within our estuaries and along our coastline are particularly vulnerable to flooding from the sea. SEPA currently estimates that there are around 26,000 homes and businesses at risk from coastal flooding in Scotland.

Current predictions for climate change anticipate an increase in sea levels, storm surges and waves all around Scotland’s coastline; however, this will affect some regions more than others.  The number of properties at risk is predicted to increase, as well as the frequency and severity of flooding in our coastal communities.

Coastal flood watch service

Our coastal Flood Watch service covers nine broad coastal areas and are issued by SEPA flood warning duty officers, based on the information that we receive from the Met Office, Storm Tide Forecasting Service. This uses a model to forecast sea levels around the coast based on predicted tides and weather conditions. When the predicted sea levels suggest a risk of flooding, flood watches are issued. This indicates that localised flooding may occur within the next 12 to 24 hours (one or two tidal cycles).

The flood warning scheme on the Firth of Clyde combines tidal information, sea level data acquired from monitoring stations and computer modelling of predicted scenarios. This is used to assess the likelihood of flooding in communities covered by the scheme.

How do I find out if a coastal Flood Watch has been issued?

It is possible to find out if any alerts have been issued through the Floodline information service on 0845 988 1188 or by clicking here.

Contacting Floodline by telephone for the first time will involve going through a menu of options to select the area you are interested in. To save time, a list of all the quick-dial numbers for coastal Flood Watch areas are listed below.

To use the quick-dial codes call 0845 988 1188, press option 1 and enter the appropriate quick-dial code for your area.  If you experience difficulty in using the service, you can speak directly to an operator by selecting ‘0’.

SEPA is looking at future development of coastal flood warning schemes and is currently working on identifying suitable communities. At the moment it is not possible to provide detailed coastal flood warnings for all areas because detailed forecast models and monitoring equipment are required to design and implement a flood warning scheme, and these must be targeted at specific at risk communities.

In the meantime, we have introduced coastal Flood Watch to provide broad information to the whole of Scotland.
