[ca] La Riera de Canyars situada entre els municipis de Castelldefels i Gava conforma un eix que connecta diversos espais amb una gran pressio urbanistica i humana com el parc natural del Garraf, el Parc Agrari del Baix Llobregat i el mar. Aquesta riera es troba emplacada en l?unic espai lliure d'urbanitzacio entre Barcelona i Castelldefels. Es un espai que connecta de forma ficticia dos espais protegits (El Parc Natural del Garraf i el Parc Agrari) L'ambit d'estudi es centra en una petita part de tota la conca de la Riera de Canyars, concretament, en la part mitjana de la conca de la Riera delimitada a banda i banda per les poblacions de Castelldefels i Gava, i per altra banda per dues carreteres, la C-245 i la carretera de la Sentiu. Tot aquest conjunt d'infraestructures i poblacions actuen com a embut i en epoques de grans riuades provoquen problemes d'inundacions que afecten a les ciutats i a molts dels terrenys que formen part del Parc Agrari. A mes a mes, aquestes riuades transporten grans quantitats de materia organica generada per l'erosio i grans quantitats de residus que contaminen altres ambits com poden ser els canals del Parc Agrari o el mar. L''objectiu de la proposta es aportar una solucio que eviti la problematica de les inundacions, que redueixi l'erosio, i que de forma indirecta generi un espai obert a l'us public evitant que segueixi sent un entorn oblidat, marginal i degradat. Aixi com, preservant el seu valor natural com a connector al conjunt d'espais naturals a l'Area Metropolitana La proposta consisteix en generar unes bases de laminacio que permetin recollir i acumular l&#8217;aigua provinent de la Riera en periodes de precipitacio elevada, aconseguint aixi disminuir el risc d&#8217;inundabilitat, i efectes d&#8217;erosio del sol . Al mateix temps generem espais que permetin la interaccio entre la fauna, la flora i la poblacio, tinguen com a element principal, l&#8217;aigua.

[en] The Canyars stream between the municipalities of Castelldefels and Gava forms an axis that connects several spaces with a great urban an human pressure such as the garraf natural park, the Baix Llobregat Agricultural Park and the sea. The Riera is located in the single free space of urbanitzation between Barcelona and Castelldefels. It's a space that connects in fiction of two protected spaces (the Garraf Natural Park and the Agricultural Park) The field of study focuses on a small part of the entire basin of the Canyars stream, specifically, in the upper part of the river basin boundedd on either side by the towns of Castelldefels and Gava, and by another take the road on two roads, the C-245 and the Sentiu road. All of this set of infrastructures and populations act a funnel and at times of great floods they cause flood problems that affects the cities and many og the lands that are part of the agricultural park In addition, these floods carry large amounts of waste that pollite other areas such as the channels of the agriculturals park or the sea. The objective of the proposal is to provide a solution that avoids the problems of floodin, which erosion, and indirectly generates an open space for public use, while avoiding a forgotten marginal and degraded enviroment. As well as preserving its natural value as a connector to the set of natural spaces in the Metropolitan Area. The proposal consists in generating lamination bases that allow to collect and accumulate the water from the Canyars River during periods of high precipitation, thus reducing the risk of floodability and effects of soil erosion. At the same time we generate spaces that allow the interaction between the fauna, the flora and the population, have as main element, the water.
