“…For Lund, although the storm water system is designed to accommodate further development of the city, increased rainfall intensity of 20-30 % would result in significant flooding problems for the city's sewage network (Niemczynowicz 1989). Semadeni-Davies et al (2008b) showed that for Helsingborg, the impacts of urbanisation and climate change could be more than met by implementing current developments in urban water management.…”

“…Consequently, urban areas, which are characterised by fewer storage elements than rural basins, would respond with further decreases in storage capacity and enhanced run-off (Niemczynowicz 1989). The impacts of changing precipitation patterns on drainage and sewage systems have mainly been assessed by studies using hydrological modelling systems with various assumptions about future precipitation amount (Niemczynowicz 1989;Semadeni-Davies et al 2008a, b;Nie et al 2009). The modelling studies usually use climate scenarios based on different global and regional climate model results (Semadeni-Davies et al 2008a, b;Olsson et al 2009).…”

“…The projected increase in heavy precipitation and rapid snow melt events (Chap. 11) could cause surface flooding due to undersized urban drainage and sewage systems such as in Porvoo (Virkki et al 2006), Loviisa (Virkki et al 2006), Helsingborg (SemadeniDavies et al 2008b, Kalmar (Olsson et al 2009), Lund (Niemczynowicz 1989), Stockholm (Sverige 2007) and Uppsala ). For Lithuania, as well as snow, frozen ground was considered to affect roads, communication infrastructure and buildings (Taminskas et al 2005).…”

“…Inflow volumes to drainage and wastewater systems are likely to increase under a warmer climate and to increase the occurrence of surface flooding and overflow of sewage systems and associated environmental problems if current systems remain unchanged (Niemczynowicz 1989;Semadeni-Davies et al 2008a;Nie et al 2009;Olsson et al 2009;Plósz et al 2009). For Lund, although the storm water system is designed to accommodate further development of the city, increased rainfall intensity of 20-30 % would result in significant flooding problems for the city's sewage network (Niemczynowicz 1989).…”

“…The modelling studies usually use climate scenarios based on different global and regional climate model results (Semadeni-Davies et al 2008a, b;Olsson et al 2009). Time scales range from single rainfall events to annual precipitation amounts (Niemczynowicz 1989;Semadeni-Davies 2004;Semadeni-Davies et al 2008a, b;Nie et al 2009;Olsson et al 2009). In addition to climate change, other developments such as population growth and ongoing urbanisation can influence urban drainage systems due to increased soil sealing and removal of vegetation, among others (SemadeniDavies et al 2008a).…”

This chapter examines observed and potential future climate change impacts on socioeconomic fields concerning urban complexes in the Baltic Sea basin. This is based on the literature review that focused mainly on English publications on climate change impacts, but included some publications in other languages on adaptation. In the Baltic Sea basin, there appears to be an imbalance between cities and towns that have been well studied with reference to climate change impacts, and cities or even regions for which there is hardly any published literature. For those publications that do exist, most concern the impact of a specific climate change effect (temperature rise, extreme events, sea-level rise) on a particular socioeconomic field of an urban complex. The results of the literature review indicate that urban complexes in the Baltic Sea catchment are likely to experience climate change impacts within wide-ranging contexts: from urban services and technical infrastructure, to buildings and settlement structures and to the urban economy or population. Impacts will differ depending on the location of the urban complex: northern versus southern and coastal versus inland. IntroductionThis chapter examines observed and potential future climate change impacts on socio-economic fields concerning urban complexes. Urban complexes are human-dominated settlements with relatively higher population density than rural settlements. The term comprises cities and towns. Urban complexes are further characterised by high concentrations of buildings and built-up areas with consequent soil sealing, high concentrations of people and infrastructure as well as specific economic and cultural roles and activities. These factors render urban complexes particularly vulnerable to climate change impacts (Hunt and Watkiss 2011). As every urban complex is characterised by a specific mix of social, ecological and economic interdependencies and its own settlement and building structure, it is difficult to generalise on scientific findings concerning urban complexes. Moreover, in the Baltic Sea basin, there seems to be an imbalance between cities and towns that have been well studied with reference to climate change impacts, and cities or even regions for which there is hardly any published literature. For those publications that do exist, most concern the impact of a specific climate change effect (temperature rise, extreme events, sea-level rise) on a particular socioeconomic field of an urban complex. Systematic case studies are available but are mostly on the impacts of climate on human health (Analitis et al.

Projected Change—River Flow and Urban Drainage

North Sea Region Climate Change Assessment

View full text Add to dashboard Cite

Hydrological extremes, largely driven by precipitation, are projected to become more intense within the North Sea region. Quantifying future changes in hydrology is difficult, mainly due to the high uncertainties in future greenhouse gas emissions and climate model output. Nevertheless, models suggest that peak river flow in many rivers may be up to 30 % higher by 2100, and in some rivers even higher. The greatest increases are projected for the northern basins. Earlier spring floods are projected for snow-dominated catchments but this does not always cause an increase in peak flows; peak flows may decrease if higher spring temperatures lead to reduced snow storage. An increase in rain-fed flow in winter and autumn may change the seasonality of peak flows and floods. The proximity of a river basin to the ocean is also important; the closer the two the greater the potential damping of any climate change effect. In urban catchments, the specific characteristics of the drainage system will dictate whether the net result of the climate change effect, for example the projected increase in short-duration rainfall extremes, is to damp or amplify the impact of this change in precipitation. The response in terms of sewer flood and overflow frequencies and volumes is highly non-linear. The combined impact of climate change and increased urbanisation in some parts of the North Sea region could result in as much as a four-fold increase in sewer overflow volumes.
