“…Rapid urbanization, such as building construction, industry and transport, cause an increase in the area covered by concrete and pavement and a reduction in natural terrain that has the capability of natural rainfall water infiltration (Markovič et al, 2014). This increases the threat of inland flooding and causes various problems related to urban water resources.…”

There is an urgent need to develop an urban rainwater drainage system in cities that have been facing flooding due to heavy rainfall events. In Japan, many municipalities have provided financial support for installing household‐level rainwater infiltration and harvesting facilities. However, the use of domestic installations is still limited. This study used the contingent valuation method (CVM) to investigate household preferences for rainwater tanks and a rainwater infiltration inlet (RII) in Yokohama, Japan, and examine the factors influencing the respondents' willingness to pay (WTP). We found that public perceptions of these systems have remained low. The mean WTP was US$265 and US$274 per unit for RII and a rainwater tank, respectively. When compared with the actual market price, the WTP results indicate that respondents had a high interest in these systems. Moreover, income, the experience of flooding and environmentally conscious behaviour were the main affecting factors.

“…Land use -Due to the impervious nature of asphalt, urban areas tend to carry more water as overland flow during a flooding event. Permeable soils, such as forested areas and bare land, on the other hand, have a higher infiltration rate than asphalt, leading to a significant percentage of water being lost to infiltration in case of a rainfall or flooding event (Markovič et al, 2014). This raster was resampled to match the 1-metre resolution of the other layers.…”

The Maritime province of Nova Scotia has seen coastal flooding become a more frequent phenomenon during the past decades due to the changing climate regime. This has influenced the interest provincial and federal governments have in flood risk modelling, who often incorporate Geographic Information Systems (GIS) as useful tools in their analysis. Incorporating LiDAR-derived digital elevation models (DEMs) in their workflows is the next step in hydrological analysis, as LiDAR-derived DEMs offer high resolution data for the analysis of flood risk without the need to rely on biotic or hydrological data. This study aims to follow this theme in order to model the effects of inland flooding in the low relief landscape of the Mersey River, located in Queen’s County, Nova Scotia, and its effects on the infrastructure built along the river network. The analysis included multi-criteria evaluation (MCE) methods coupled with a stochastic simulation approach in order to determine areas where vulnerability is the most certain. Results indicated that high flood risk is present in urbanized areas within 1 km of the Mersey River at a low degree of uncertainty, making them the best candidates for flood-preventive measures. The accuracy provided by LiDAR-derived DEMs supported a high-quality workflow for the MCE and DEM error analysis, proving their utility for floodplain delineation. The addition of historical and hydrological data to future projects could build on the results presented in this study, adding more to the literature on flood risk modelling along the Mersey River.

Proper management of rainwater in cities has a significant impact on improving the environmental conditions: the microclimate of a city by regulating the water cycle and reducing heat islands; developing of biodiversity; increasing health and well-being of residents. The aim of the article was to present the possibilities of improving the environmental conditions in compact urban development areas-those that additionally contribute to the shaping of architecture, and thus combine the ecological, functional, and aesthetic benefits. The article draws attention to the synergy of climate change and the new way of developing urban areas, which was presented on the example of specific solutions functioning on the transformed urban area: Clichy-Batignolles in central Paris-recognized as a model for environmental solutions, labelled Éco-Quartier. The mentioned conditions and solutions were related to the possibility of shaping urban form, with the obligation to discharge some or all of the rainwater on the building plot. On the basis of the calculations made for the runoff ratio in individual quarters, it was found that it is possible to maintain a compact urban structure and effectively manage rain water provided that appropriate engineering and urban solutions are applied. These solutions can have an architectural value. The conclusions from the analyses can be used to formulate guidelines for other European cities, which are increasingly faced with the problem of water scarcity and uncontrolled flooding.
