  • Urban flood risk assessment using sewer flooding databases

    Sustainable water management is a global challenge for the 21st century. One key aspect remains protection against urban flooding. The main objective is to ensure or maintain an adequate level of service for all inhabitants. However, level of service is still difficult to assess and the high-risk locations difficult to identify. In this article, we propose a methodology, which (i) allows water ...

  • Methodology for qualitative urban flooding risk assessment

    Pluvial or surface flooding can cause significant damage and disruption as it often affects highly urbanised areas. Therefore it is essential to accurately identify consequences and assess the risks associated with such phenomena. The aim of this study is to present the results and investigate the applicability of a qualitative flood risk assessment methodology in urban areas. This methodology ...

  • Subsidence of peat soils in South-East Asia – Flooding risks in Sarawak

    There is an increase in awareness of the carbon emissions resulting from peatland drainage and peat fires. There is in general however a lack of recognition of the link between carbon loss and peatland subsidence, i.e. lowering of the soil surface. This paper presents the case study of the Rajang Delta in Sarawak, Malaysia where peatland subsidence will cause flooding, rendering 50% and ...

  • Flooding of lowland peatlands in Southeast Asia

    Vast lowland areas of Southeast Asia will be frequently and irreversibly flooded before the end of the century unless action is taken to stop the destruction of peatlands. A radical change in land-use is needed. In particular the palm oil and pulp wood sectors must stop developing new plantations on peat and plan to phase-out existing drainage-based plantations before they are flooded. If no ...

  • Flood risks and environmental vulnerability — Exploring the synergies between floodplain restoration, water policies and thematic policies

    Nowadays floodplain areas are reduced in size or no longer function as active floodplains, thereby impacting on the delivery of environmental services to local and regional communities and economies. These services include regulating services such as protection against floods or water purification; provisioning services, such as nutrient collection and fertile soil formation; and cultural ...

  • Grow in concert with nature : green water defense for flood risk management in East Asia

    This summary note presents the key concept and approach of Green Water Defense for flood risk management in East Asia. East Asia is home to more than a quarter of the world's population. It saw impressive economic growth in the past decade, accompanied by rapid population growth and urbanization. As a result, land and water resources in this region are under increasing pressure leading to ...

  • Modelling the Thatcham Flood - Case Study

    Overview On 20th July 2007, an unusual storm swept west across England along the approximate line of the M4 motorway. Thatcham, a town in Berkshire, was one of the worst affected. Many towns in England flooded that month from the Humber to Tewksbury. In fact there were 200 major floods worldwide in 2007 affecting 180 million people. Some of these floods were caused by rainfalls much more ...

  • Green infrastructure for flood-risk management in Dar es Salaam and Copenhagen: exploring the potential for transitions towards sustainable urban water management

    The risk of flooding in urban areas could be better approached by complementing conventional sewer systems with sustainable urban drainage systems (SUDS) for storm-water management. This may be the case for developing world cities like Dar es Salaam with incomplete sewer services, as well as cities like Copenhagen with fully developed sewer systems. This paper explores some theories relevant to ...

  • Risk is much more than a game

    Wildfires and flooding affect many more people in the USA than earthquakes and landslide and yet the dread, the perceived risk, of the latter two is much greater than for those hazards that are more frequent and cause greater loss of life. Research published in the International Journal of Risk Assessment and Management, suggests that a new paradigm for risk assessment is needed so that ...

  • Uncertainty-based flood resiliency evaluation of wastewater treatment plants

    Wastewater treatment plants (WWTPs) have a significant role in urban systems’ serviceability. These infrastructures, especially in coastal regions, are vulnerable to flooding. To minimize vulnerability, a better understanding of flood risk must be realized. To quantify the extent of efforts for flood risk management, a unified index is needed for evaluating resiliency as a key concept in ...

  • Sea Level Rise: Risk and Resilience in Coastal Cities

    Introduction One of the most dire impacts of anthropogenic climate change is a rise in the global sea level caused by the melting of glaciers and land-based ice caps, as well as a smaller increase from expansion due to the higher temperature of the water itself.  Unlike some other predicted effects of climate change, this impact has already been observed for some time.  Indeed, ...
