dc.description.abstract | Permeable pavements are one type of sustainable urban drainage system. Although they are not new, their use is very limited as an integrated element of the urban drainage network, and the lack of confidence in their operation may be one of the reasons for that. The aim of this article is to offer an updated vision of the existing knowledge on permeable pavements, so that practitioners have more tools available for their implementation. Thus, not only the description of permeable pavements will be analysed, but also their impacts on the management of the urban stormwater networks, as well as some design criteria. All of this from a hydrological-hydraulic point of view, highlighting the volume and flow reduction for surface dis-charges, but also taking into account water quality. At the end, a description of an area built to investigate this type of pavement will also be given, highlighting its benefits.; Zoladura iragazkorrak hirietako drainatze-sistema jasangarri mota bat dira. Ez dira berriak, baina oso mugatua da hirietako drainatze-sareko elementu integratu moduan duten erabilpena; besteak beste, sistema horien funtzionamenduarekiko konfiantza-ezagatik. Artikulu honen helburua zoladura iragazkorren inguruan dagoen ezagutzaren inguruko ikuspegi eguneratua ematea da, Administrazio eta enpresetako teknikariek inplementaziorako tresna eskuragarri gehiago izan ditzaten. Horrela, zoladura iragazkorren deskribapena emateaz gain, hirietako saneamendu-sarearen kudeaketan dituzten inpaktuak aztertuko dira, baita diseinurako irizpide batzuk eskainiko ere. Guztia ikuspuntu hidrologiko-hidrauliko batetik egingo da, azaleko isurketen bolumen- eta emari-murrizketa nabarmenduz, baina uraren kalitatea ere kontuan harturik. Bukaeran, zoladura mota hauek ikertzeko eraiki den eremu baten deskribapena ere emango da, haren erabilgarritasuna azpimarratuz. | |
