DOTTY MCLEOD: The headlines have been dominated by the devastation that flood waters have brought to the North of England over the last few weeks. Cambridgeshire has been spared the heavy rainfall this year, but one Cambridge academic has warned that instead of floods, the greatest challenge facing this county could be chronic water shortages in the coming years. Of course Cambridgeshire hasn’t always escaped flooding. In 1947 much of Fenland was inundated as rivers and drains broke their banks. These people remember what happened.
ONE: The Sunday night was very bad. Wind, the men had to rope themselves together on the banks to stop from falling into the river. Yes I were out on them banks and breaching them up with sandbags.
TWO: I went up to Earith because I’d heard rumours the bank had blown. When I got there it was really frightening. The bank was really shaking.
THREE: The one journey that I really recollect is the night that I was called out to go to Hilgay. The water in the river was so high that it was coming over.
DOTTY MCLEOD: There were also of course the terrible East Coast floods of 1953, when 300 people died, and as a result of that, a large scale flood protection scheme was introduced. Since then the flooding we’ve experienced in Cambridgeshire, although it’s always awful for anyone whose home is affected, it has normally been fairly localised. Dr Bob Evans is a Visiting Fellow at the Global Sustainability Unit at Anglia Ruskin University. Morning Bob.
BOB EVANS: Good morning.
DOTTY MCLEOD: Are we prepared then for the kind of deluge that we’ve seen in the North of England here in Cambridgeshire?
BOB EVANS: Well the North of England has had about three times its average rainfall in December. That is fairly rare.
DOTTY MCLEOD: Its average annual rainfall?
BOB EVANS: No no. Average for December.
DOTTY MCLEOD: OK.
BOB EVANS: So it’s an enormous amount of rainfall. We’ve had just over the average. So one of the reasons is we’ve had a lot less rainfall, and at the moment we’re coping. The river levels, I cross Jesus Green nearly every day and they’re not very up at all. And that’s been so for quite a long time.
DOTTY MCLEOD: Suppose we did have that kind of level of rain that they’ve seen in places like Cumbria, three times the average. Would we just be inundated here?
BOB EVANS: We would I think be more like what you’ve just been saying on the radio, that it would be local. Because it would be a question of how quickly you could shift the water through the system. And generally when we’ve had big floods it’s because the water can’t get out quickly, because the sluice at Denver is not allowing the water to go out to sea, because the tidal levels are very high. So you’d usually need two things to get really massive flooding. So I think you’ll just get local flooding, which as you say is fairly horrendous for the people who are affected. It won’t be massively around the Fens.
DOTTY MCLEOD: Now you say that actually water shortages are something that we’re more at risk of in the long term.
