Urbanizacija, kot civilizacijski proces širjenja mestnega načina življenja je povzročil spremembe v površinskem odtoku padavinske vode oziroma je povrzočil spremembe v lokalnem ali urbanem vodnem krogu. Sedanji (v veliki meri netrajnostni) sistem odvodnje v kombinaciji s podnebnimi spremembami oz. pogostimi ekstremnimi dogodki, predstavljajo dodatne razloge za spremembe v upravljanju z vodami. Izvedba sonaravnih rešitev omogoča trajnostno urbano odvodnjo ter hkrati ustvarja okolju prijazna, trajnostna in prijetna območja. S svojimi fizikalnimi in biološkimi procesi vplivajo na povečano infiltracijsko sposobnost mest, zadrževanje padavinske vode na mestu nastanka in na boljšo kakovost voda ter omogočajo njeno ponovno uporabo ali bogatenje podtalnice. Urbani prostor v tem kontekstu predstavlja edinstven sistem, ki je zaradi človeškega posega v naravo, zelo občutljiv na hidrološke spremembe. V nalogi smo?opredelili primerne sonaravne rešitve za ravnanje s padavinsko vodo. Predstavili smo nekatere primere že izvedenih sonaravnih rešitev na področju urbane odvodnje v Sloveniji: zelene strehe, zadrževalniki padavinske vode, zeleno parkirišče in prepustni beton. Na primeru načrtovanja parkirišča prikažemo uporabnost sonaravnih rešitev za upravljanje s padavinskimi vodami. Growing Uurbanization has caused changes in the surface rainfall runoff and consequently in used changes in the local or urban water cycle. In addition to the current drainage system, which is unsustainable, climate change caused by human development is an additional reason for the necessary changes in water management. Implementation of nature-based solutions can lead to sustainable urban drainage, and at the same time create environmentally friendly, sustainable and comfortable spaces. Sustainable drainage systems, through their physical and biological processes, affect water purification and allow its reuse or infiltration into the soil. In this context, the urban areas represent a highly man-made system, which is very sensitive to hydrological changes (caused by climate change). In this work, we selected suitable nature-based solutions that can successfully address the challenges of the urban water cycle. A few Slovenian examples of nature-based solutions that were already implemented in the field of urban drainage are presented: green roofs, dry ponds, green parking and permeable concrete. A parking lot case study was used to illustrate the usefulness of nature-based solutions for urban water management. |
