Reports from experts in the Mammal Society are indicating that the reintroduction of beavers might help alleviate the flooding problems affecting parts of the United Kingdom.
Beavers became extinct in the UK throughout the 16th century due to hunting but their dam construction skills could be helpful in tandem with man-made alternatives.
Society Chief Executive Marina Pacheco said that the river systems are in a bad state, which has to be acknowledged, and that special help is needed to find the floods in check. She’s advocating the reintroduction to begin at the most flood prone areas to see their most immediate advantages.
Beavers are reintroduced in Scotland since May 2009 and are what’s called a’keystone’ species.
This water is then release at a lesser speed than man-made drains now do.
This might help alleviate the flooding downstream and are a very economical measure.
However Ola Holmstrom, UK Head of Water at consultancy company WSP, has been quoted as stating that dredging is’hotly debated as a flood hazard mitigation step within the hydrological community’. Experts say that the river station only has little water compared with the flood plain and elimination of material will not increase capacity but not considerably.
And while the presently used system of getting the water into the sea as fast as possible still has its own merits, problems are only being transferred along the drainage route. Improving the movement of the water via one place can only raise the possibility of flood down the line at another.
The suggestion is to concentrate on the upstream areas and increase the ability to hold water . This comes with the advantage of becoming substantial more cost efficient than dredging.
Ultimately it may arrive at the point at which flood plains are reverted to just that and not used for farming or housing. With all the changes in the climate, it may come about that there’s simply no simple solution to repair the issue in certain areas like the Somerset Levels, which is almost totally under sea level and has seen horrible flood.
