ANALYSIS: small is beautiful when it comes to flood protection

As a series of unprecedented storms continue to wreak havoc on the country, Dr Angela Connelly, from The University of Manchester who has just completed research into innovative new flood technologies, argues we can no longer rely on large scale flood defences.

“The appalling storms battering Britain are bringing flood misery to people living in many parts of the country. But when the clean-up really does start, those people so badly affected will want to know if there is more that can be done to deal with future threats. Long term actions may be some way off, but these are important questions which should be raised now, particularly in light of David Cameron’s commitment to offer 5, 800 households up to £5000 to make their homes more resilient.

In a case study of dams on the upper Missouri River, USGS researchers have demonstrated that an upstream dam is still a major control of river dynamics where the backwater effects of a downstream reservoir begin. In light of this finding, the conventional understanding of how a dam can influence a river may have to be adjusted to account for the fact that effects of river dams can interact with one another.

“We have known for a long time that dams have dramatic effects on river form and function,” said Jerad Bales, acting USGS Associate Director for Water. “In the past, however, the effects of dams generally have been studied individually, with relatively little attention paid to how the effects could interact along a river corridor.” (more…)
