Archive: Cardiff floods in 1979
Emergency services are taking part in a major exercise to replicate serious flooding across south Wales.
Exercise Polygon will set different scenarios - including people trapped in homes in a flooded Cardiff and concerns over high water levels at the Pontsticill dam above Merthyr Tydfil.
As well as fire and rescue, police, lifeboat and ambulance crews, mountain rescue and the RSPCA will be involved.
Here is footage of flooding in Cardiff from December 1979 - before the barrage in the Bay was built - when 3,000 houses were flooded.
