In an article in the Guardian about the floods in York, at http://www.theguardian.com/environment/2015/dec/27/floods-army-called-continue-devastate-northern-england , I read about the flood barrier on the River Foss that

[begin quote]

Problems arose at the weekend at the Foss barrier and pumping station, which controls river levels by managing the interaction between the rivers Foss and Ouse. In a model that is commonplace around the country, pumps behind the barrier are supposed to pump the water clear. The station became inundated with floodwater after the volume exceeded the capacity of the pumps and flooded some of the electrics, according to an Environment Agency spokesperson, who said that a helicopter was due to airlift in parts to complete repairs on Monday.

It is particularly ironic that flood-control measures are rendered ineffective through flooding of their controls. But it's not a one-off.

At the beginning of this month, much of the city of Lancaster (and reportedly 55,000 people) were left without power when an electricity substation in Caton Road was flooded in a previous storm http://www.bbc.com/news/uk-england-lancashire-35020049

Roger Kemp's take on the Lancaster affair is at http://www.lancaster.ac.uk/news/blogs/roger-kemp/who-decided-to-put-lancasters-main-electrical-substation-next-to-the-river/

There is more to consider. Lots more.
