  • Urban flooding caused by climate change: what will be the impacts?

    Heavy rain and snow induced by climate change could cause significant damage in urban areas. A recent model study estimates the impact on a Swedish city and suggests there could be an increase in the number of surface floods by 25-45 per cent during this century. Since 1998, floods in Europe have caused some 700 deaths, the displacement of about half a million people and at least EUR 25 billion ...

  • Baltimore region embraces program to locate, map, assess and repair water distribution assets

    Over the past decade, the City of Baltimore has seen vast improvements in control point operability and system sustainability of its water distribution assets. The report card is looking better each year. The Baltimore City Department of Public Works shoulders a big responsibility.  The Department provides 265 million gallons of water daily to 1.8 million ...

  • Grass and trees in urban areas help reduce flood risk

    Sealed surfaces, such as roads and buildings, in urban areas increase the amount and speed of water flowing overland during and after prolonged or heavy rainfall. Urban runoff typically flows into drainage systems for stormwater, which may not be able to handle large volumes of water, ...

  • Compensating for re-directed flooding

    Flood prevention actions can redirect flooding to another location. A new French survey indicates that current local compensation policies to deal with this situation may be financially unviable. It suggests more practical solutions would involve insurance schemes and state intervention, as well as local water management institutions. The EU Directive on the Assessment and Management of Flood ...

  • Environmental risks of urban creep

    A recent study published in the Water and Environment Journal has shown that permeable hardstanding solutions should be promoted through legislation, education and incentives. With the aim of supporting any proposed changes to Scottish building regulations, the authors investigated the impact of hardstanding on flood risk and water quality. Urban development generally leads to an increase in ...

  • City of Waterloo Uses 2D Urban Flood Modelling to Evaluate Stormwater Management Alternatives

    During the past 5 years the City of Waterloo, Ontario has been receiving an increasing number of reports of localized flooding of residential properties and roadways in some of the older neighborhoods of the city. In one particular area, a sag in the road way and low-lying adjacent properties have resulted in significant flood damage to several homes and pooling of water in excess of 1 m deep ...


  • The Ebb and Flow of Urban Water

    The average homeowner in Canada pays about a penny for every three litres of water they consume. Because water is so cheap, not many people pay attention to their water bills. Nor do they think twice when they pay over a hundred times as much for virtually the same water in a plastic bottle purchased at a convenience store. We flush our toilets, wash our laundry and brush our teeth every day ...

  • Urban water ecology

    Sewage overflows are a fact of life in urban areas, and in many cities, excess sewage water enters streams and lakes with rain runoff. Although this pollution is harmful to most organisms, there is one group of insects that thrives on it: mosquitoes. Luis Fernando Chaves, a post-doctoral researcher at Emory University, and his team discovered mosquitoes in abundance in a sewage-contaminated ...

  • Consequences of climate change and flood protection

    Acqua alta has a section on 'Maritime visions and projects', where star architect Hadi Teherani will present his 'Living Bridge' project, a bridge with housing and shops on it. A Living Bridge is to be created in Hamburg, about 700 metres long and 60 metres wide, linking the inner city and the urban districts to the south of the Elbe. 'This concept for cities by the water creates an intensive ...

  • Early warning system for pluvial flooding

    An early warning system for pluvial flooding caused by surface water runoff has been developed and could be implemented in the near future. The method offers greater warning and better targeting of resources. Pluvial flooding occurs when large volumes of surface water, typically from heavy rainfall, accumulate causing overland flow and ponding which is unable to drain away. Urban underground ...

  • Super `floodway` mooted for Thai floods

    Researchers from a Thai university have come up with a proposal for a 'super express' floodway to help reduce the impact of future flooding on Thailand's capital, Bangkok. The idea came from Chulalongkorn University's Unit for Disaster and Land Information Studies and would make use of existing ...

  • Water and flood modelling practices and solutions

    The dates and a call for papers for the 2010 European Water and Flood Modelling Conference have been announced. The event, a comprehensive and significant wet infrastructure simulation and management technology gathering, will be held 28th and 29th September 2010, at the Crowne Plaza, Reading, UK. This once-a-year learning opportunity for the European expert modelling community will feature ...

  • Predicting contamination of farmland after flooding

    Floods and the resulting damage to agricultural and urban environments are likely to increase as a result of climate change. Major floods in Europe, such as those affecting the Elbe River in Germany in August 2002, can result in contamination by heavy metals of flooded farmland. Taking zinc as an example, a new modelling approach showed that there was more than a one in three chance that ...

  • Building urban resilience to climate change

    Certain characteristics make the urban environment particularly vulnerable to heat, flooding and water scarcity. For example, buildings and road surfaces store heat and prevent water from draining away, while in times of water shortage, high population density and the demands of industry put pressure on water sourced from the surrounding regions. As climate change intensifies, it will exacerbate ...

  • Modifying urban rivers to increase biodiversity

    Urban rivers are typically heavily-engineered and polluted with degraded habitats. They are therefore a priority for biodiversity restoration. Research suggests that relatively simple modifications to river walls may potentially encourage biodiversity by significantly improving habitats for plants and animals. The EU’s Water Framework Directive requires good ecological status in surface waters by ...

  • Sustainability is key to quality of urban life

    A new report suggests that modern urban areas provide high standards of living and prosperity, but are less successful in delivering 'quality of life' to all citizens. If local, national and European authorities focus on sustainable living, they can drive new social, cultural and economic initiatives needed to protect the environment and secure the long-term future of city dwellers. 'Quality of ...

  • New UK approach to flood risk management

    The statement stresses that to realise full benefit, resilience measures will need to contribute to creating quality urban environments and to managing the wider aspects of the water cycle. Chair of the multi-institutional group David Balmforth said: 'Flooding is a very real risk in the UK and one that is only going to get worse. If we rely solely on flood defences and ever larger drainage ...

  • Asian cities head global list of flood vulnerability

    The rapid growth of cities across the developing world has resulted in urban areas overtaking rural communities as being the most vulnerable to widescale flooding, according to a report from the World Bank. The slums of Asian cities are especially vulnerable, says the report, pointing out that about 90 per cent of people exposed to floods live in Asia, and that the problems they face could ...
