Green roofs and living walls are effective tools for addressing water management challenges in urban environments. These green infrastructure elements can mitigate rainwater runoff, reduce water contamination, and support more sustainable flow regulation. They also contribute to temperature regulation and provide habitat support for urban wildlife. Careful plant selection can maximize the positive impact of green infrastructure, reducing pollution levels and improving water quality in densely populated urban areas with extreme weather conditions. The research presented in this article raises awareness about potential challenges and risks associated with green infrastructure, such as pollutant release. Understanding the factors that influence water quality enables improved management practices and sustainable urban planning. The article also identifies various plant species with remarkable contaminant retention capabilities, particularly several metals such as calcium and sodium. These findings propose the design of effective green infrastructure solutions. This study confirms that green infrastructure effectively filters pollutants from precipitation water, making it suitable for injection into underground water wells. Overall, the research provides valuable scientific insights for urban water management, fostering eco-friendly and resilient cities in semi-arid climates.

Adaptation to climate change often aims to increase the ability of cities to retain water. In recent years, there has been a shift in the approach to managing storm water from traditional methods to nature-based methods, which view storm water as a valuable resource. This study conducted a systematic analysis of eleven contemporary housing estates that are commonly considered sustainable. The study aimed to identify the elements of rainwater management and determine whether these elements form a system. The research found that, in most cases, not all elements of a rainwater management system (RMS) were present. The housing estates in Gdańsk and Gdynia demonstrated some features of an RMS but were still incomplete due to missing elements such as channels and gaps in curbs that guide rainwater. The results suggest that the implementation of some elements of an RMS does not necessarily create a fully functional system. A fully effective RMS requires the integration of all necessary elements to allow water to flow between them.

Tereny naturalne często zamieniane są na powierzchnie utwardzone czy uszczelnione. Stopień uszczelnienia powierzchni oraz infrastruktura komunikacyjna i hydrotechniczna w znacznym stopniu wpływają na zmianę relacji opad–odpływ na danym obszarze. Wszystkie te czynniki pociągają za sobą konsekwencje, których skutkiem często są liczne i gwałtowne powodzie. W artykule dokonano oceny wpływu rodzaju powierzchni na wielkość odpływu wód deszczowych z obszaru naturalnego i zurbanizowanego oraz wpływu uszczelnienia terenu na hydrogramy odpływu.

Natural areas are often converted into paved or sealed surfaces. The degree of surface sealing, public transport and hydrotechnical infrastructure significantly alter the rainfall-runoff relationship in the area. All these factors entail consequences which often result in numerous and severe floods. The paper assesses the impact of surface conditions on the size of storm water runoff from both natural and urban area and the impact of seals on land runoff hydrographs.
