Van der Westhuysen, A. (author), Van Dongeren, A. (author), Van Nieuwkoop, J. (author), Groeneweg, J. (author), Eslami Arab, S. (author)Over the last five years a research program has been carried out to assess the performance of the spectral wave model SWAN in the Wadden Sea so that it may be used for the transformation of offshore wave conditions to wave boundary conditions near the sea defenses (dikes and dunes). The assessment was done on the basis of extensive wave...report 2011

Groeneweg, J. (author), Burgers, G. (author), Caires, S. (author), Feijt, A. (author)This report presents the joint KNMI and Deltares Plan of Approach for the wind modelling activities for the coming years, with the goal to determine time and spatially varying extreme wind fields. These are required as input for the 2017 safety assessment of the primary water defences. The objectives of the project have been defined as follows:...report 2011

Husrin, S. (author)Results showed that the existing model on erosion of clay with water-filled cracks (Führböters theory) which only considers cohesion as the soil strength is only applicable for certain conditions. The model should consider other resistant forces such as soil weight and pore pressures. From the tests on clay without water-filled cracks, it...report 2009

Lesniewska, D. (author)Failure of natural and man-made earth structures is an important environmental hazard in many climatic conditions with significant socio-economic impact. Failures usually appear as sudden catastrophic events. Actually they are triggered by much slower processes of a progressive nature, occurring within the earth mass without any visible external...report 2009

This report aims to provide a comprehensive reference of flood inundation models for the flood manager. We begin by describing the processes important for flood propagation, the equations for modelling these processes, the simplifications and assumptions. Examples of each type of model are given, the limits and capabilities of each model or...report 2009

Wijdeveld, A. (author)Flooding not only induces a risk which is related to direct loss of life for humans, animals and plants. During flooding, toxicants which are normally stored or otherwise unavailable might be released. The spreading of these pollutants during the flooding or, often more important, the persistent presence of toxicants in the soil or sediment...report 2009

Tapsell, S. (author)Task 10 focuses on developing innovative methods to understand, model and evaluate socio-economic and ecological flood damages. The four main activities within the Task are: building a model to estimate risk to life modelling the damage-reducing effects of flood warnings toxic stress and use of the OMEGA modelling framework to predict...report 2009

Hall, J. (author)Task 20 has contributed to the methods and application of uncertainty analysis by targeting novel areas of uncertainty analysis and decision support. The research fell into four sub-tasks: 1) Development of an overall framework for uncertainty analysis in flood risk management decisions. 2) Development of new methods to deal with the uncertainty...report 2009

Meyer, V. (author)Evacuation is a response to the immediate or forecast threat of flooding that is expected to pose a risk to life, health or well-being. It involves people moving from their houses or places of business to safe locations, out of the flood risk area where they are able to shelter until it is possible and appropriate for them to return. This...report 2009

Morris, M. (author), Hassan, M. (author), Kortenhaus, A. (author), Visser, P. (author)This report provides an overview of the state of the art with regards to embankment breach initiation and formation processes. Basic breach formation processes are explained, including a review of commonly held misconceptions. The different stages of breach initiation and formation are also explained, along with the varying needs of different...report 2009

Hassan, M. (author)The IMPACT Project (www.impact-project.net) provided valuable data on breach formation processes. Five large scale field tests were performed in Norway, and a further 22 laboratory tests were performed in the UK. A review of this data has been undertaken to support breach model testing and development under Task 6.report 2009

Priest, S. (author)A methodology has been developed to estimate loss of life from flood events. In order to reduce the risk to life it is necessary to understand the causes of loss of life in floods and what kind of intervention and flood risk management measures may be effective in eliminating or reducing these losses. Data on flood events were gathered from 25...report 2009

Van Mierlo, T. (author)This document can be considered as a kind of cookbook for preparing flood maps. The cookbook was made in the framework of the PPA04/SK/8/13 project entitled Determination of inundation area. The project focussed on the transfer of knowledge in the field of preparing flood maps as required in the Slovak Water Act and resorts under the EVD....report 2009

Kuze, T.. Helmuth, O.; Görner, C.; Bernhover, C. (author)A series of sensitivity studies have been performed to estimate the impact of presumed global warming on synoptic scale weather events. Within the framework of an epignostic study, mesoscale simulations of the Elbe river flood (August, 2002) employing the COSMO-DE model of the DWD have been carried out. The first set of runs was realised on a...report 2008
