Need to re-map flood plains in Wales, river expert claims

Lives and homes are in danger because the flood risk in Wales is being underestimated, according to a rivers expert.

Aberystwyth University's Prof Mark Macklin said magnitudes could be 40% greater than planned for in some areas.

He said Natural Resources Wales (NRW) is failing to use all historical data to predict the risks.

A NRW spokesman said its flood maps were not underestimating the problem but it was considering using the data.
