“…2a, b), which exists in many urban environments (Bauer et al, 2002;Lu et al, 2014;Kaspersen et al, 2015). Linear regression models (Table S1 in the Supplement) developed by Kaspersen et al (2015) relating the soil-adjusted vegetation index (SAVI) to levels of imperviousness were applied to estimate IS fractions for the four cities both historically and for the present day.…”

Abstract. The economic and human consequences of extreme precipitation and the related flooding of urban areas have increased rapidly over the past decades. Some of the key factors that affect the risks to urban areas include climate change, the densification of assets within cities and the general expansion of urban areas. In this paper, we examine and compare quantitatively the impact of climate change and recent urban development patterns on the exposure of four European cities to pluvial flooding. In particular, we investigate the degree to which pluvial floods of varying severity and in different geographical locations are influenced to the same extent by changes in urban land cover and climate change. We have selected the European cities of Odense, Vienna, Strasbourg and Nice for analyses to represent different climatic conditions, trends in urban development and topographical characteristics. We develop and apply a combined remote-sensing and flood-modelling approach to simulate the extent of pluvial flooding for a range of extreme precipitation events for historical (1984) and present-day (2014) urban land cover and for two climate-change scenarios (i.e. representative concentration pathways, RCP 4.5 and RCP 8.5). Changes in urban land cover are estimated using Landsat satellite imagery for the period 1984-2014. We combine the remote-sensing analyses with regionally downscaled estimates of precipitation extremes of current and expected future climate to enable 2-D overland flow simulations and flood-hazard assessments. The individual and combined impacts of urban development and climate change are quantified by examining the variations in flooding between the different simulations along with the corresponding uncertainties. In addition, two different assumptions are examined with regards to the development of the capacity of the urban drainage system in response to urban development and climate change. In the "stationary" approach, the capacity resembles present-day design, while it is updated in the "evolutionary" approach to correspond to changes in imperviousness and precipitation intensities due to urban development and climate change respectively. For all four cities, we find an increase in flood exposure corresponding to an observed absolute growth in impervious surfaces of 7-12 % during the past 30 years of urban development. Similarly, we find that climate change increases exposure to pluvial flooding under both the RCP 4.5 and RCP 8.5 scenarios. The relative importance of urban development and climate change on flood exposure varies considerably between the cities. For Odense, the impact of urban development is comparable to that of climate change under an RCP 8.5 scenario (2081-2100), while for Vienna and Strasbourg it is comparable to the impacts of an RCP 4.5 scenario. For Nice, climate change dominates urban development as the primary driver of changes in exposure to flooding. The variation between geographical locations is caused by differences in soil infiltration properties, historical t...

“…The methodologies that present specific area of IS, considered the small cuts of larger agglomerations only and IS cover varied from 15-98% (Boyd et al 1993) or 44-46% (Miller et al 2014). There was just one case where the area of a greater UC part was evaluated (Bauer et al 2004) and the proportion of IS varied from 37 to 58%. The percentage of the IS cover of the UC is an important environmental indicator.…”

The risks of accelerated runoff and its larger amounts brought by urbanisation include increased flood flows and pollution of downstream ecosystems. One of the most significant permanent effect of urban sprawl is soil sealing, which alters natural infiltration and runoff. In addition to imperviousness, the increased runoff from sealed and compacted surfaces results in increased sedimentation of stream ecosystems with contaminants. In most urban planning strategies, water related ecosystems have already become the fundamental components of the integrated urban landscape management, but still have been referred to as objects of protection or rehabilitation; not as management tools. This paper shows how soil sealing significantly affects urban environment and urban ecosystems health. It also demonstrates significant impacts of a city on downstream ecosystems. Data obtained from orthophotomap vectorization showed that the model urban catchment is relatively highly urbanized. 45% of model area is sealed mainly with buildings (40.41%), streets (31.01%), and parking lots (25.28%). Compared to natural basins, urban runoff is 64 times higher and carries a significant amount of pollutants.

“…Impervious surfaces are primarily associated with human transportation (streets, highways, parking lots, and sidewalks) and rooftops of buildings, which represent the imprint of land development on the landscape. Therefore, imperviousness is generally used to quantify and map the degree of urbanization and the extent of urban land use (Civco et al, 2002;Yang et al, 2003;Bauer et al, 2004). More importantly, imperviousness is a useful environmental indicator that can be used to measure the impacts of urbanization on surface runoff, water quality, air quality, biodiversity and microclimate (White and Greer, 2006;Luo et al, 2009;Lee et al, 2010).…”

Impervious surfaces are the result of urbanization that can be explicitly quantified, managed and controlled at each stage of land development. It is a very useful environmental indicator that can be used to measure the impacts of urbanization on surface runoff, water quality, air quality, biodiversity and microclimate. Therefore, accurate estimation of impervious surfaces is critical for urban environmental monitoring, land management, decision-making and urban planning. Many approaches have been developed to estimate surface imperviousness, using remotely sensed data with various spatial resolutions. However, few studies, have investigated the effects of spatial resolution on estimating surface imperviousness. We compare medium-resolution Landsat data with high-resolution SPOT images to quantify the imperviousness in Beijing, China. The results indicated that the overall 91% accuracy of estimates of imperviousness based on TM data was considerably higher than the 81% accuracy of the SPOT data. The higher resolution SPOT data did not always predict the imperviousness of the land better than the TM data. At the whole city level, the TM data better predicts the percentage cover of impervious surfaces. At the sub-city level, however, the ring belts from the central core to the urban-rural peripheral, the SPOT data may better predict the imperviousness. These results highlighted the need to combine multiple resolution data to quantify the percentage of imperviousness, as higher resolution data do not necessarily lead to more accurate estimates. The methodology and results in this study can be utilized to identify the most suitable remote sensing data to quickly and efficiently extract the pattern of the impervious land, which could provide the base for further study on many related urban environmental problems.
