Integrating Urban Pluvial Flood Mitigation Measures and Systems for Heating and Cooling in the Urban Water System: Design for A Resilient New Theatre in Gouda

Heavy precipitation results in high pressure on the urban water system. This leads to pluvial flooding and overflowing of the sewer system into the surface water. In order the mitigate the impact of these events, separate sewer systems and water storage facilities are implemented in cities. Surplus water overflowing from surface water or sewer...

Resilient and Equitable Accessibility: Taking into account societal vulnerability in decision making on the placement of flood adaptation policies in an urban setting

Transportation systems are being put under increasing pressure in urban areas. These systems are concentrated, highly used and vulnerable to rainfall-induced disruptions. Improving the resilience of infrastructure systems to these disruptions has become a vital aspect of managing an urban area that is both economically viable as well as liveable...

A rainfall threshold-based approach to early warnings in urban data-scarce regions: A case study of pluvial flooding in Alexandria, Egypt

Rapidly expanding cities in the Middle Eastern and North African (MENA) region are at risk of flooding due to heavy rainfall, insufficient drainage capacity, a lack of preparedness and insufficient data to conduct required studies. A low regret Early Warning Systems (EWS) using rainfall thresholds is proposed as a cost-effective short-term...

A probabilistic approach to estimating residential losses from different flood types

Residential assets, comprising buildings and household contents, are a major source of direct flood losses. Existing damage models are mostly deterministic and limited to particular countries or flood types. Here, we compile building-level losses from Germany, Italy and the Netherlands covering a wide range of fluvial and pluvial flood events...

Urban pluvial flooding prediction by machine learning approaches – a case study of Shenzhen city, China

Urban pluvial flooding is a threatening natural hazard in urban areas all over the world, especially in recent years given its increasing frequency of occurrence. In order to prevent flood occurrence and mitigate the subsequent aftermath, urban water managers aim to predict precipitation characteristics, including peak intensity, arrival time...

The influence of land subsidence on pluvial flooding in Rotterdam: Supplementing conducted stress test pluvial flooding with land subsidence assessment

In the Netherlands, the Delta Programme aspires to adjust spatial planning climate-proof and water-resilient, in order to be prepared for extreme weather in 2050. To achieve this ambition, municipalities, provinces, regional water authorities and central governments conduct stress tests to map out the vulnerabilities in their areas of authority...

Adaptive planning of stormwater management measures to mitigate pluvial flooding under climatic and socio-economic uncertainties

The undertaken thesis work conducts a research study based on the study area — Laakhaven, The Hague, to develop an implementation example of the Adaptation Pathway approach, in order to support long-term adaptive stormwater management planning on urban adaptation measures to mitigate pluvial flooding under the climatic and socio-economic...

Midtown: Right in the MIDst of a climate resilient and vibrant HousTOWN

Houston, TX is known for being flood prone. Recent disasters such as Hurricane Harvey (2017) severly damaged this city. Houston’s flooding problem is caused by urban sprawl, the flatness of the city and the lack of policy. The urban sprawl increases the amount of concrete and limits the city’s natural drainage, the flatness of the city means the...

Critical rainfall thresholds for urban pluvial flooding inferred from citizen observations

Urban pluvial flooding is one of the most costly natural hazards worldwide. Risks of flooding are expected to increase in the future due to global warming and urbanization. The complexity of the involved processes and the lack of long-term field observations means that many crucial aspects related to urban flood risks still remain poorly...

FloodCitiSense: Early Warning Service for Urban Pluvial Floods for and by Citizens and City Authorities

FloodCitiSense aims at developing an urban pluvial flood early warning service for, but also by citizens and city authorities, building upon the state-of-the-art knowledge, methodologies and smart technologies provided by research units and private companies. FloodCitiSense targets the co-creation of this innovative public service in an urban...

Assessing different modelling concepts for estimating pluvial flooding in urban areas

Our climate is changing. In the Netherlands, higher rainfall intensities and longer periods of drought are expected in the coming years. Urban environments have to be adapted in order to maintain (or improve) the living standards that we have set for today. Models of the urban drainage system play a vital role in the identification of flood...

Cartagena, it's now or never: A study on reducing flood risk in Cartagena de Indias, Colombia

This report is the result of a study which aims to understand both the source and severity of flood risk in Cartagena de Indias, Bolívar, Colombia. Solutions to the problem are proposed accordingly. The flood risk is found to be severe and urgent enough to demand action. Currently annual damage and negative impact of inundations are severe...

Quantitative analysis of urban pluvial flood alleviation by open surface water systems in new towns: Comparing Almere and Tianjin eco-city

Increased surface runoff generated in urban areas due to larger proportion of impervious surfaces has, in many cases, exceeded the capacity of urban drainage systems. In response to such challenge, this paper introduces the quantitative analysis of pluvial flood alleviation by open surface water systems in the case of Almere in the Netherlands...

Flood safety in delta cities: Development of a comprehensive risk-based model to support decision making on measures against pluvial, riverine and coastal flooding in urban area, with the application to Hoboken, New Jersey

Flood safety in low-lying delta regions has been a challenge of all ages. Societies worldwide have been trying to protect themselves against flood hazards for centuries. Floods in vulnerable urban regions are often caused by heavy rainfall, high river flow, extreme sea levels, or combinations of those three. Currently, there is a lack of tools...

On rainstorm damage to building structure and content

Rain, catch it if you can

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...

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...
