Tiivistelmä
The thesis examines the contemporary issue of climate change and its effects on stormwater management in Finland. The purpose of the thesis is to understand and explore stormwater management practices in the context of climate change-related extreme weather events, particularly focusing on heavy rainfall events and the subsequent stormwater flooding in built-up areas.
The thesis begins by examining the extreme weather events with the help of climate change scenarios and how these events impact on stormwater management.
The thesis then explores stormwater’s impact on built-up environments, shedding light on why it is important to manage stormwater. It subsequently moves on to address the current legislation and guidelines related to stormwater management providing an overview of the current situation of stormwater management in Finland.
Furthermore, the thesis discusses the current stormwater management methods and designs used in Finland such as open ditches, swales, and culverts that fall under conveyance method, detention basins, wetlands, and prefabricated water storages that fall under detention methods, and infrastructures such as stone beds, infiltration trenches, prefabricated systems that fall under infiltration methods to get a good picture of current stormwater management practices in Finland.
Stormwater management practices from Norway, China and the USA are also briefly examined to see whether any methods or practices that could be applied in Finland. The thesis recommends continuation of nature-based solutions in Finland, specifically emphasizing on permeable surfaces, underground storages and modern forecasting and control systems to manage and minimize stormwater flooding risks, particularly in the inner parts of built-up areas, where there has been flooding in the past.
