Can I extend my sympathies to all those affected in South Wales Central by this most distressful event and the experiences that followed of seeing your homes flooded? It's the speed at which it happens—I think you've referred to that. It is astonishing. In my 21 years in the Chamber, when I've talked to flood victims, speed is what they say, which means we need the most effective warning systems possible.

Can I praise the joint work between the Welsh Government and the UK Government? I know there have been a few things flying about the Chamber today, but actually, both sides seem to have co-operated very well, and you need to continue this. I do commend the fact that the Secretary of State, Simon Hart, did visit RCT on Friday.

My main point is that we do need, because of climate change, to look at the whole hydrology of the south Wales catchment area. We have very fast-moving rivers. They're short. The energy they possess is astonishing, and quite frankly, some of the culverts are not fit for purpose for the speed of the water flow. We need to look at these water courses and examine them in the whole system, about what can be done to deepen them and strengthen them and move that water away from the areas at most risk around businesses and homes.
