Territorial Studies Focused on the Heat Island of the Ostrava Agglomeration and the Risk Posed by Rainwater Infiltration

Part of the activity was implemented in Phase 1 and its outcomes will be evaluated and updated in Phase 3 of the project

Partners involved in the activity: Moravian-Silesian Region

At the end of the first phase of the project, two key spatial studies were produced as part of this activity:

• evaluation of the Ostrava agglomeration in terms of the risk of overheating,
• localization of areas of the Moravian-Silesian Region at risk of rainwater infiltration

Both studies will serve as an important basis for municipal spatial planning, as municipalities play a key role in the region's adaptation to climate change.

The risk of urban overheating is a serious problem that needs to be addressed. Densely built-up areas overheat in summer, which endangers the health of residents, increases energy consumption for cooling and clearly reduces quality of life. The study helps to identify the most vulnerable areas and suggests measures such as planting trees, green roofs or permeable surfaces.

The issue of urban overheating is also closely related to rainwater infiltration. Impermeable surfaces prevent natural drainage, which also increases the risk of flash floods or water loss in the landscape. In addition, some areas have unstable bedrock, perhaps due to former mining. The study helps to identify locations at risk from rainwater infiltration and suggests effective solutions, such as recommendations for the construction of retention areas or surface finishes.

Phase 3 of the project will evaluate how municipalities are using the results of the studies in their land use plans and decision-making processes. Based on this assessment, the studies will be updated to better respond to new climate challenges and needs from the region.
