Flood prevention
I recently chanced upon the website of the Flood Prevention Society, a voluntary organisation that tries to shape public policy on flooding. Their website has a long and detailed report on some of the floods in recent years and, for those with less time on their hands, a snappy "Urban myths about flooding" page. They seem less than impressed with the Environment Agency, and indeed with George Monbiot's ideas about grouse moors and flooding. I reproduce the whole thing here.
1. “Increased flooding is because of more land drainage”.
The opposite is true. During the last Great War and for years after to produce more food and later help the balance of payments, farmers were given a 50% capital grant by Governments to clean ditches, brooks and land drainage. This grant ceased over 30 years ago – so while flooding is on the increase, land drainage is on the decrease.
2. “Modern farming with heavy tractors and machinery causes a plough pan seal (compaction) in the land preventing it soaking up rain, so the rain runs straight into rivers”.
Modern farmers also use subsoilers that break up any plough pan letting air and moisture penetrate up and down – so no change.
3. “Rainfall running off moorland causes urban flooding”.
