During the peak on 15 and 16 February 2020 there were 61 flood alerts, 89 flood warnings and two severe flood warnings in force.That is more warnings for rivers than Wales has ever had at any one time,The station there consists of a small brick-built hut and a number of measuring devices that are fixed in the water and on the riverbanks. The focal point is a river level gauge, which looks like a huge ruler.
Paul said: "What this does is monitor the velocity of particles travelling underneath from the river and at the same time it will track the depth and a cross-sectional area of the bed as well and that gives us the flow. It's a fairly simple calculation. At the office in Cardiff, maps of Wales' rivers cover the walls and the computer screens allow the team to visualise the data and detect trends.
