Diolch yn fawr, Llywydd. Minister, the topography of the Glamorgan and Gwent valleys has always made them highly susceptible to flooding, often flash flooding, and the planning system, therefore, is very, very important in building up resilience. Some of the traditional methods used in other parts of the country, like bunding, are not practical. We've really got to think about how we manage these very fast moving water courses. To date, we're hearing again very, very old stories about culverts blocking and debris in river courses. This has to be constantly looked at and repaired and maintained.
