  • What is a Flood Risk Assessment?

    Flood Risk Assessments (FRA) are becoming a very important part of the planning permission process. It interlocks with other areas of the planning process, and could cause weeks or months of delays if not done from the beginning. But what is a Flood Risk Assessment? A Flood Risk Assessment is a series of tests that are carried out to assess the level of flood risk of a given location. The ...

  • Modelling and Managing Flood Risk and Flooding

    The UK’s prestigious Royal Society recently held a discussion group on the subject of Flood Management and Climate Change. With much of the Northern Hemisphere approaching the winter flooding season, we spoke to Wallingford Software’s David Fortune to find out the role of modelling in flood forecasting and flood management. He set out his ideas as follows: We must remember first that, while we ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Uncertainty assessment and risk analysis of steam flooding by proxy models, a case study

    Many uncertainties exist in development of oil fields. Developing proxy models as substitutes for reservoir simulators is a fast method for uncertainty analysis. Artificial neural network (ANN) and polynomial regression models (PR) were used as proxy models in a sector of an Iranian heavy oil reservoir under steam flooding scenario. Screening analysis was used to find influential uncertain ...

  • Matter-element model of integrated risk assessment for flood control systems

    The matter-element model of integrated risk assessment for flood control systems is established with matter-element analysis theory and correlative function of extension set, on the basis of classification of flood situations and risk indexes of typical flood control works. By this model, quantitative indexes of integrated risk assessment can be derived for flood control systems on a basin or ...

  • An influence diagram for urban flood risk assessment through pluvial flood hazards under non-stationary conditions

    Urban flooding introduces significant risk to society. Non-stationarity leads to increased uncertainty and this is challenging to include in actual decision-making. The primary objective of this study was to develop a risk assessment and decision support framework for pluvial urban flood risk under non-stationary conditions using an influence diagram (ID) which is a Bayesian network (BN) ...

  • 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 ...

  • Flood mapping, a core component of European flood risk management

    Flood mapping is a crucial element of flood risk management. Directive 2007/60/EC on the assessment and management of flood risks will require Member States to prepare two types of maps by 2013. Flood hazard maps, showing the extent and expected water depths/levels of an area flooded in three scenarios, a low probability scenario or extreme events, in a medium probability scenario (at least with ...

  • 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 ...

  • The impact of network simplification on property flood risk predictions

    A recent project, set up to compare the merits of simplified and desimplified models in InfoWorks CS, has proved that the solution’s fast and robust simulation capabilities are now so advanced that highly-complex models can provide far greater accuracy at competitive speeds than smaller, simpler models. As the water industry moves towards a risk-based approach to flooding, the existing ...

  • 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 ...

  • Assessing national flood management using a sustainable flood management framework

    This paper presents a prototype framework for sustainable flood management at the national level which features stakeholder participation, and is modified and applied to a case study. Through literature reviews and an interview survey of South Korea (the case study country), the causes of recent flood damage are found to be heavy rainfall due to climate change, urbanization, insufficient channel ...

  • Methodology for risk assessment of flash flood events due to climate and land-use changes: application to the Llobregat basin

    Global change, including climate, land-use and socio-economic changes, is expected to increase the stress on the entire water cycle. In the Mediterranean region, extreme events are likely to increase due to climate change. This work, framed in the EC Seventh Framework Programme project IMPRINTS, presents a methodology to obtain future flood risk maps using climate and land-use scenarios, ...

  • Development of a screening method to assess flood risk on Danish national roads and highway systems

    A method to assess flood risk on Danish national roads in a large area in the middle and southern part of Jutland, Denmark, was developed for the Danish Road Directorate. Flood risk has gained renewed focus due to the climate changes in recent years and extreme rain events are expected to become more frequent in the future. The assessment was primarily based on a digital terrain model (DTM) ...

  • Assessment of riverside groundwater flood risk induced by high river water levels using a numerical model and monitoring data

    Large barrages have been constructed on the main rivers in South Korea to store water and mitigate fluvial flooding damage. However, the increase in water levels behind the barrages can potentially lead to a rise in groundwater levels in the riversides. The purpose of this study was to describe the effect of a barrage on groundwater levels and to test the applicability of a numerical model to ...

  • A GIS-supported 3D approach for flood risk assessment of the Qu'Appelle River, Southern Saskatchewan

    This research introduces a hybrid approach for flood risk assessment through GIS. The developed approach is based on the integration of hydraulic simulation and GIS analysis, which allows spatial-based visualisation and prediction of flood disaster. In particular, the Hydraulic Engineering Center River Analysis System (HEC-RAS) model is employed to simulate multi-scenario flood cases within a ...
