A high-level group of engineers and architects have been called in by Number 10 to advise the government on tackling flooding in the UK, 黑洞社区 can reveal.

Following a recent meeting of the Cobra government emergency committee, prime minister David Cameron announced that leading experts had been called to meet at Downing Street to help the government work on a 鈥渓ong-term solution to alleviate the risk of flooding鈥�.

It has now emerged that the group includes Arup鈥檚 global research leader Jeremy Watson; civil engineer Jeremy Benn of engineering and environmental consultant JBA; engineers from the Chartered Institution of Water and Environmental Management; and Robert Barker, the co-founder of Baca Architects, which is working on the UK鈥檚 first amphibious house and the government-funded Life project on flood-risk initiatives.

The experts met Sir Mark Walport, the government鈥檚 chief scientific adviser, earlier this month. It is now expected that the group will offer ongoing advice.

Barker said: 鈥淣ational policy establishes some general flooding guidance but general guidance isn鈥檛 going to be the solution to some of these overwhelming challenges in places like Somerset and Lincolnshire - where 90% of some regions are flood plain.

鈥淭he government needs to support greater innovation in planning and architecture, to live with and make space for water.鈥�

Benn said the group had initially discussed immediate challenges such as 鈥渞emoving water in the Somerset Levels鈥�.

Walport is already involved in considering how urban areas respond to future challenges such as climate change through the government鈥檚 Future of Cities research project.

A Number 10 spokesperson said: 鈥淭he government鈥檚 chief scientific adviser has been consulting with relevant experts.

鈥淭here is a range of work ongoing on what can be done around issues of flooding and flood defence. We fully expect that to carry on for the foreseeable future but obviously things are at quite an early stage.鈥�

The news of the advisory group emerged as a group of architects, engineers, surveyors and ecologists urged the government to convene a 鈥渃ross-departmental conference鈥� with construction professionals to develop a long-term strategy to manage flooding.

In a letter to the Telegraph - signed by the chair of the RICS, the president of the Chartered Institution of 黑洞社区 Services Engineers, and the heads of 15 other professional bodies - the professionals said government needed to mobilise their 鈥渏oint expertise鈥�.

The letter said: 鈥淲ater management techniques could have helped prevent the effect of flooding on villages, towns and over surrounding land seen recently.

鈥淓mergency measures are in order for the immediate crisis. But in the long term, the management of water requires a clear strategy.鈥�

The letter said that Sustainable Urban Drainage Systems (SUDs) needed to be fitted to all new buildings.

It said: 鈥満诙瓷缜鴖 and land that cannot be properly protected should be made resilient to withstand flooding.鈥�

It concluded: 鈥淲e are asking David Cameron to convene without delay a cross-departmental conference, including the professions, with the Department of Energy and Climate Change, the Department for Environment, Food and Rural Affairs, the Department for Communities, the Environment Agency and National Resources Wales, similar to the one convened to address the problem of ash dieback.鈥�

Meanwhile, the government鈥檚 climate change watchdog, the Committee on Climate Change (CCC), warned that current plans for spending on flood defences, through to 2021, are as much as 拢1.4bn below the level required to ensure that the flood risk for homesacross the country does not increase.

It said that as a result, 250,000 more homes would become exposed to 鈥渟ignificant risk of flooding by 2035鈥�.

In its detailed analysis of flood defence spending by the Department for Environment, Food and Rural Affairs, the CCC warned the funding shortfall meant the government was storing up 拢3bn or more of costs in future years as a result of avoidable flood damage.

In the analysis, published in response to the debate over flood spending, the CCC said that when comparing current spending plans against the Environment Agency鈥檚 long-term investment strategy, an additional 拢20m plus inflation would need to be spent on flood defences each year for the next 25 years just to 鈥渉old constant the number of properties at significant flood risk over time鈥�.

It said an extra 拢50m plus inflation a year would be required to 鈥渕ake headway and reduce the number of properties at risk鈥�.

The watchdog said analysis of spending on flood defences showed that every 拢1 spent on average prevents 拢8 in future flood damage: 鈥淭he current ratio implies that each 拢1 taken from the programme means expected future flood damages will be 拢8 higher than otherwise.

鈥淰alue for money will be less strong amongst schemes on the margin, perhaps achieving 拢6 in benefits per 拢1 spent.

鈥淏ut even at this more modest rate of return we can expect an extra 拢3bn in avoidable flood damages in future years because spending this period is half a billion pounds behind the identified need.鈥�
