  • Decision making in flood risk based storm sewer network design

    It is widely recognised that flood risk needs to be taken into account when designing a storm sewer network. Flood risk is generally a combination of flood consequences and flood probabilities. This paper aims to explore the decision making in flood risk based storm sewer network design. A multi-objective optimization is proposed to find the Pareto front of optimal designs in terms of low ...

  • Towards two-way flood risk communication: current practice in a community in the UK

    Despite the considerable progress in engineering works, flooding continues and is now recognized as a major and increasing challenge. This realisation has resulted in a shift in flood risk management from leaning heavily on structural measures to the incorporation of non-structural initiatives, such as communication about flood risks that is considerate of the diversity existing within ...

  • Combining Socio-Technical and Ethical DImensions of Flood Risk Mitigation

    The aim of the current research was to develop a methodology that combines social, technical and ethical dimensions for flood risk assesment and evaluation of flood mitigation measures. A unique combination of scientific, social and ethical approach was developed to fulfil the objectives . Social justice criteria were developed with the purpose to assess in qualitative and quantitative way the ...

  • Flood Risk and Social Justice

    Flood Risk and Social Justice is a response to the rising significance of floods and flood-related disasters worldwide, as an initiative to promote a socially just approach to the problems of flood risk. It integrates the human-social and the technological components to provide a holistic view. This book treats flooding as a multi-dimensional human and natural world tragedy that must be ...

  • Flood risk modelling based on tangible and intangible urban flood damage quantification

    The usual way to quantify flood damage is by application stage-damage functions. Urban flood incidents in flat areas mostly result in intangible damages like traffic disturbance and inconvenience for pedestrians caused by pools at building entrances, on sidewalks and parking spaces. Stage-damage functions are not well suited to quantify damage for these floods. This paper presents an alternative ...

  • The efficiency of asset management strategies to reduce urban flood risk

    In this study, three asset management strategies were compared with respect to their efficiency to reduce flood risk. Data from call centres at two municipalities were used to quantify urban flood risks associated with three causes of urban flooding: gully pot blockage, sewer pipe blockage and sewer overloading. The efficiency of three flood reduction strategies was assessed based on their effect ...

  • The EU Floods Directive trickling down: tracing the ideas of integrated and participatory flood risk management in Sweden

    This study examines how the EU Floods Directive – an extensive and innovative legislative instrument for integrated and participatory flood risk planning in all EU member states – influences local flood risk management in one member state, Sweden. The study identifies that: many municipalities have received new knowledge; cross-sectoral organisational structures for water and flood risk issues ...

  • Vulnerability proxy selection and risk calculation formula for global flood risk assessment: a preliminary study

    By using the data from 15 countries in Asia, this study aims to improve the current global flood risk assessment methods in the aspects of vulnerability proxy selection and a risk calculation formula. In estimating global flood risk, the current methods treat vulnerability in a very simplistic manner. Based on recent literature and empirical findings, this study classifies vulnerability into ...

  • Public Engagement

    Today people often do not have any relation to the river they live nearby. Knowledge and comprehension of possible danger and the handling with floods is missing, especially in areas, where a flood haven't occurred for long time. Information and education is necessary to raise flood risk awareness. Depending on target group (e.g. pupil, residents) different approaches were used. The ...

  • London flood risk

    A Greater London Assembly report in 2011 stated that there was a 'serious risk' of flooding if London faces severe rainfall. Regardless of the Thames Barrier – which is there to protect against flooding from the sea, the London Assembly’s Environment Committee claim that some streets could flood from rain within minutes. Rainfall equal to what other parts of the country experienced in ...

  • Method for consequence curves as applied to flood risks

    This article summarises research intended to expand current study methodologies targeting flood risks with regard to specific issues and emergency preparedness requirements of municipalities. Various methods are currently available to predict the consequences of flooding risks. DOMINO is one such tool used to study flooding risks from natural events or from potential dam breaks. A complementary ...

  • Reassessing flood frequency for the River Trent through the inclusion of historical flood information since ad 1320

    The estimation of return periods for floods likely to have significant societal impact is challenging unless suitably long records exist. Relatively few sites across the UK provide a continuous record of river level or discharge over 50 years, whilst records extending back to the nineteenth century are rare. This represents a significant problem in providing robust and reliable estimates of ...

  • Development of priority setting process for the small stream restoration projects using multi criteria decision analysis

    This study performed a flood risk assessment using one of the multi criteria decision-making methods to identify the small stream basins with high risk of flooding and to determine the optimal small stream restoration measures by priority ranking for flood risk. The 12 representative factors for the flood risk assessment were carefully selected and constructed for the three main aspects, such as ...

  • Efficient joint probability analysis of flood risk

    Flood attributes such as the water level may depend on multiple forcing variables that arise from common meteorological conditions. To correctly estimate flood risk in these situations, it is necessary to account for the joint probability distribution of all the relevant forcing variables. An example of a joint probability approach is the design variable method, which focuses on the extremes of ...

  • Flood hazards in the headwaters area: lessons learned from a survey of households in the upper Myjava basin, Slovakia

    The aims of this paper are to present knowledge about the threat of flooding in the upper basins of the Myjava River, obtained using a questionnaire, and to identify the potential lessons for flood risk management. The questionnaire was designed to obtain information about households' experience with flooding, including the type of floods experienced, the locations of flooding, the ...

  • Flood risk management plans 1

    Flood risk management plans (FRMPs) contain an approach for saving or improving flood protection within a river basin. They shall address all aspects of flood risk management focusing on prevention, protection and preparedness (EC 2007). FRMPs include the conclusion of the preliminary flood risk assessment, the flood hazard maps and flood risk maps. Furthermore they should contain: description ...

  • Flood risk maps 2

    Flood risk is a combination of the likelihood of flooding and the potential consequences arising. There are different maps depending on the chosen hydrological scenario (see flood hazard maps). The flood risk maps should consider information about: the number of potentially affected inhabitants the type of economic activity on the area potentially affected other information ...

  • Losing memory – the risk of a major flood in the Paris region: Improving prevention policies

    This paper provides a snapshot of the key findings of an Organisation for Economic Co-operation and Development (OECD) review of flood risk prevention policies in the Paris metropolitan area. With an innovative flood risk assessment, the study shows that a major flooding of the Seine River, similar to the flood disaster of 1910, could affect up to 5 million residents in the greater Paris area ...

  • Flood and Coastal Risk Management - Case Study England

    The Environment Agency is the principal flood risk management operating authority. It has the power (but not the legal obligation) to manage flood risk from designated main rivers and the sea. These functions in relation to other rivers (defined as ...
