Wave-induced vibrations of flood gates: modelling, experimentation and design

Flood gates form an essential part of many flood defence systems in coastal areas. During storm events, these gates are subjected to extreme loads from various sources. This dissertation addresses the dynamic behaviour of flood gates induced by wave impacts. A semi-analytical fluid-structure interaction model is developed to predict vertical...

Riverine flood risk screening with a simple network-based approach: A proof of concept in the Ganghes-Brahmaputra basin

Floods cause major problems around the world. Over 35 million people were affected by floods in 2018. They have a growing worldwide impact on life and property. Changes in climate conditions lead to unanticipated variations in glacial runoffs, snowmelt and precipitation, which all significantly changing river flows. An imbalance in river network...

Including stochastic rainfall distributions in a probabilistic modelling approach for compound flooding due to tropical cyclones: A case study for Houston, Texas

Hurricanes impose great threats on coastal communities in terms of hazard and impact. Recent hurricanes like Harvey (Texas, 2017) and Idai (Mozambique, 2019) emphasize the global character of this threat. In the U.S., Hurricane Harvey tied with 2005's Hurricane Katrina as the costliest tropical cyclone on record, inflicting $125 billion in...

Analysing the effects of extreme precipitation for municipalities and waterboards: Do they need to connect their sewer and surface water models?

The world’s climate is changing. In the Netherlands one of the consequences is that water boards and municipalities are preparing for an increase in extreme precipitation. To evaluate the consequences in case of extreme precipitation all Dutch municipalities and water boards have to perform a stress test. In these stress tests the response of...

Flood Safety in the Clarence Valley: Feasibility study into flood mitigation measures to make 'Room for the River'

The Clarence River catchment is located in the state of New South Wales (NSW), on the east coast of Australia. The lower Clarence Valley is an area covering approximately 1000 square kilometers and is located on the downstream part of the Clarence River. Due to heavy rainfall, the Clarence River discharge can increase from an average 160 m3/s to...

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...

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...

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...

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...

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...

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....

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.
