Wow - what a flame war! Shows the media are winning - short snappy psuedo-science loaded facts are far easier to digest than real science - and sell more papers/attract more web hits.
Four comments on points raised so far:
1. Dredging was actually done in most (not all) places to allow navigation and keep puddles out of fields. Not stop floods.
2. The dude that put the graphs up - they were for December. December was nothing impressive rainfall wise. It did saturate the catchments (in a normal winter way) so that
Januarys record rainfall was enough to tip the balance. Esp. when combined with the multiple tidal surges (induced by the low pressures from the storms) and fully recharged groundwater. before I also get ripped to shreds here - each individual storm was nothing significantly amazing - just the sheer number of them.
3. Climate change - it is happening. I'm not going to speculate against the cause. It always has changed and always will. Politics are getting in the way of increasing our resilience.
4. Dredging in the levels would not reduce the depth of flooding by more than several cm. This is a great example of my opening line.
If you care to follow up the source of information posted by the media - they cleverly missed a very important part of the phrase off. Dredging will significantly decrease the
duration of the flooding but not the
severity
Check out the CIWEM's "floods and dredging - a reality check" report - published on their
website. Dredging could make the floods last for significantly less time - but not significantly less severe.
Over and out!
