Tulvapuistoja

Tulvapuistoja, also known as flood parks or flood meadows, are man-made wetlands designed to mitigate the effects of flooding in urban areas. These parks are typically created by diverting excess water from rivers or other water bodies into a designated area, where it is allowed to spread out and infiltrate the soil. This process helps to reduce the risk of flooding downstream and can also improve water quality by filtering out pollutants.

Tulvapuistoja are often designed with a variety of plant species that can thrive in wet conditions, providing habitat for wildlife and creating a unique ecosystem. They can also serve as recreational spaces, offering opportunities for walking, cycling, and birdwatching. Additionally, tulvapuistoja can help to mitigate the urban heat island effect by providing shade and cooling the air through evapotranspiration.

The concept of tulvapuistoja has gained popularity in recent years as a sustainable and low-cost solution to urban flooding. They are particularly effective in areas with a high frequency of heavy rainfall events, such as in many parts of Europe and North America. However, the success of tulvapuistoja depends on careful planning and management, including regular maintenance to ensure the health of the ecosystem and the effectiveness of the flood mitigation measures.
