Socio-economic and ecological evaluation and modelling methodologies

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...

Laboratory Experiments on the Erosion of Clay

Results showed that the existing model on erosion of clay with water-filled cracks (Führböter’s 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...

TASK 8 – FLOOD INUNDATION MODELLING - MODEL CHOICE AND PROPER APPLICATION

This report contains the results of Task 8 of the floodsite project. It provides information on different types of inundation models and how they should be applied, given the type of area and research questions that need to be answered.

GIS-based Multicriteria Analysis as Decision Support in Flood Risk Management

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...

Review of the IMPACT Project breach field test data

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.

Estimation of the Maximum Physically Possible Precipitation in Saxony Using a Mesoscale Atmospheric Model

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...

Inundation Model Evaluation

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...

Web-based knowledge transfer: Specification for the E-Flood platform

The overall objective of Task 30 is to support the communication of the findings of the whole FLOODsite project and to promote uptake of the FLOODsite framework and methodologies by the three main target groups: public, professional and educational. The specific objective of Task 30 is to enhance uptake through the adoption of a Web-enabled...

Hydraulic model tests on breaching with and without waves

This report describes small-scaled experiments performed at Leichtweiß-Institute for Hydraulic Engineering and Water Resources, Technical University Braunschweig (LWI). The experiments have been conducted to investigate the development of dike breaches in homogeneous sand dikes with and without a clay layer. The used scaling factor was 1:10.The...

Review report of operational flood management methods and models

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...

Building a model to estimate Risk to Life for European flood events

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...

Protocols for Data Sharing within FLOODsite

The overall objective of Task 30 is to support the communication of the findings of the whole FLOODsite project and to promote uptake of the FLOODsite framework and methodologies by the three main target groups: public, professional and educational. The specific objective of Task 30 is to enhance uptake through the adoption of a Web-enabled...

Determination of inundation area (PPA04/SK/8/13) – Cookbook for preparation of Flood Maps

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....

The effects of floods and flood-induced pollution on ecosystem health

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...

Breaching Processes: A state of the art review

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...
