“…German Water Association (DWA) set up different working groups with the aim to establish technical standards and provide affected interest groups with guidelines and practical advice which in the year 2013 during a heavy rainfall event with a return period of about 100 years has proven to significantly reduce flood risk and gain acceptance in public (Fritsch et al, 2016). As a further example, Hamburg has introduced a separate rain water drainage system in recent years and introduced financial penalties, if rain water is not locally drained by home owners (Schlünzen & Bohnenstengel, 2016).…”

Pluvial flooding is a result of overland flow and ponding before the runoff enters any watercourse, drainage system or sewer, or cannot enter it because the network is full to capacity, usually caused by intense rainfall. River and coastal floods get the most attention since they are largest and last the longest, while pluvial floods are relatively marginalized in research. Therefore, the main goal of this research was to show risk posed by pluvial floods, their connection to current global climate change processes, present effects of flooding in European cities, as well as what we can expect in the future. Furthermore, the aims were to present and get more familiar with scientific projects, strategies, directives and measures devised both on national and international levels, that deal with urban pluvial flood issues across the European continent. Climate change projections indicate that there will be an increase in the frequency and intensity of rainfall events throughout Europe and along with ongoing urbanization, the problem of pluvial flooding will most certainly require more attention, which it is starting to receive. Some countries have already developed their strategies and initiatives and implemented both structural and non-structural measures, such as spatial planning, constructional measures, information systems, reducing land sealing through policies, building codes and standards, on-site improvement of retention, infiltration, evaporation, and rainfall water recycling with the use of green roofs, permeable or porous pavements, rain gardening or urban rainwater harvesting. At the same time, there are numerous research papers, studies, conferences and workshops devoted to the problem of pluvial flooding and its management carried out in an attempt to properly deal with this hazard.

“…Construction materials such as concrete and asphalt have low albedo. The thermal properties and large surface areas of urban structures lead to a high thermal inertia (Erell and Williamson 2007;Bohnenstengel et al 2011), meaning that urban structures absorb and store heat during the day and release it at night (Yamamoto 2006;Kershaw et al 2010;Schlünzen and Bohnenstengel 2016). With densely built structures, urban areas tend to lack vegetation.…”

In the UK where 90% of residents are projected to live in urban areas by 2050, projecting changes in urban heat islands (UHIs) is essential to municipal adaptation. Increased summer temperatures are linked to increased mortality. Using the new regional UK Climate Projections, UKCP18-regional, we estimate the 1981–2079 trends in summer urban and rural near-surface air temperatures, and UHI intensities during day and at night in the 10 most populous built-up areas in England. Summer temperatures increase by 0.45–0.81°C per decade under RCP8.5, depending on the time of day and location. Night-time temperatures increase more in urban than rural areas, enhancing the night-time UHI by 0.01–0.05°C per decade in all cities. When these upward UHI signals emerge from 2008–2018 variability, positive summer nighttime UHI intensities of up to 1.8°C are projected in most cities. However, we can prevent most of these upward night-time UHI signals from emerging by stabilising climate to the Paris Agreement target of 2°C above pre-industrial levels. In contrast, daytime UHI intensities decrease in nine cities, at rates between -0.004 and -0.05°C per decade, indicating a trend towards a reduced daytime UHI effect. These changes reflect different feedbacks over urban and rural areas and are specific to UKCP18-regional. Future research is important to better understand the drivers of these UHI intensity changes.

“…The anthropogenically driven UHI represents the differences in albedo, roughness, heat and moisture flux exchange of the land surface. It is increasingly recognized that localized UHI effects interacted with global climate change have considerable social-economic consequences and high potential for health impacts [6][7][8][9]. Moreover, it usually introduces a warming bias in the observed surface air temperature series, similar to that of the increasing concentration of atmospheric greenhouse gases [3,[10][11][12].…”

Continued urban expansion undergone in the last decades has converted many weather stations in Thailand into suburban and urban setting. Based on homogenized data during 1970-2019, therefore, this study examines urbanization effects on mean surface air temperature (Tmean) trends in Thailand. Analysis shows that urban-type stations register the strongest warming trends while rural-type stations exhibit the smallest trends. Across Thailand, annual urban-warming contribution exhibits a wide range (< 5% to 77%), probably manifesting the Urban Heat Island (UHI) differences from city to city resulting from the varied urban characteristics and climatic background. Country-wide average urban warming contribution shows a significant increasing trend of 0.15 <sup>o</sup>C per decade, accounting for 40.5% of the overall warming. This evidence indicates that urban expansion has great influence on surface warming, and the urban-warming bias contributes large fraction of rising temperature trends in Thailand. The increasing trend of annual Tmean for Thailand as a whole after adjusting urban-warming bias is brought down to the same rate as the annual global mean temperature trend, reflecting a national baseline signal driven by large-scale anthropogenic-induced climate change. Our results provide a scientific reference for policy makers and urban planners to mitigate substantial fraction of the UHI warming.
