A comparative survey of the impacts of extreme rainfall in two international case studies

Flooding is assessed as the most important natural hazard in Europe, causing thousands of deaths, affecting millions of people and accounting for large economic losses in the past decade. Little is known about the damage processes associated with extreme rainfall in cities, due to a lack of accurate, comparable and consistent damage data. The...

Van last naar les: Hoe publiek-private samenwerking de regenwateroverlast voor inwoners, woningeigenaren en klanten kan verlagen. Een analyse van schadegegevens en de factoren die van invloed zijn op regenwaterschade

In het Impactproject ‘Samen met verzekeraars naar een regenbestendige stad’ hebben we de werelden van een verzekeraar, onderzoeker en gemeente/waterbeheerder bij elkaar gebracht. Amsterdam Rainproof, Waternet, Achmea en TU Delft zijn de samenwerking aangegaan om de impact van extreme regenval op bewoners in Amsterdam te analyseren en te...

Decision-tree analysis of factors influencing rainfall-related building structure and content damage

Decision Tree Analysis Of Processes Generating Water-Related Building Damage: A Case Study In Rotterdam, The Netherlands

The objective of this study was to identify the main failure mechanisms behind water-related building damage and to investigate to what extent these processes are related to characteristics of buildings and rainfall events. Results are based on the mining of property level insurance damage data, for a case study in Rotterdam, the Netherlands....

Correlations between reinfall data and insurance damage data related to sewer flooding for the case of Aarhus, Denmark

Sewer flooding due to extreme rainfall may result in considerable damage. Damage data to quantify costs of cleaning, drying, and replacing materials and goods are rare in literature. In this study, insurance claim data related to property damages were analysed for the municipality of Aarhus, Denmark. The aim of this paper was to study the extent...

A spatial analysis of rainfall damage data using c-band weather radar images

Intense rainfall may locally cause considerable damage in cities, e.g. because of sewer floods. A better understanding of relationships between rainfall characteristics and rainfall-related damage can help insurers and flood authorities to respond more adequately to rainfall extremes. This paper aims to study to what extent weather radars can be...

A statistical analysis of insurance damage claims related to rainfall extremes

In this paper, a database of water-related insurance damage claims related to private properties and content was analysed. The aim was to investigate whether the probability of occurrence of rainfall-related damage was associated with the intensity of rainfall. Rainfall data were used for the period of 2003–2009 in the Netherlands based on a...

A statistical analysis of insurance damage claims related to rainfall extremes

In this paper, a database of water-related insurance damage claims related to private properties and content was analysed. The aim was to investigate whether high numbers of damage claims were associated with high rainfall intensities. Rainfall data were used for the period of 2003–2010 in the Netherlands based on a network of 33 automatic rain...

Correlations between rainfall data and insurance damage data on pluvial flooding in The Netherlands

The objective of this paper is to establish relationships between rainfall extremes and damage data from Dutch insurance industry. Rainfall data are based on a network of 33 automatic rain gauges held by the Royal Netherlands Meteorological Institute. Rainfall characteristics, such as peak rainfall intensity and rainfall volume, are correlated...

Collecting data for quantitative research on pluvial flooding

Urban pluvial flood management requires detailed spatial and temporal information on flood characteristics and damaging consequences. There is lack of quantitative field data on pluvial flooding resulting in large uncertainties in urban flood model calculations and ensuing decisions for investments in flood protection. In this paper four...

Analysis of pluvial flood damage based on data from insurance companies in the Netherlands

Insurance databases form a promising data source that can be used to improve pluvial flood damage estimations. This paper describes the key characteristics of an insurance database on water related damages to private buildings and content in the Netherlands that has been made available for research. The paper presents preliminary results of a...
