L'ús d'embarcacions d'esbarjo és una activitat molt extesa a la zona costanera del Garraf. Aquesta activitat origina fluxos energètics i materials els quals, a la vegada, són els productors d'impactes sobre el medi natural i l'entorn portuari.El uso de embarcaciones de recreo es una actividad muy extendida en la zona costera del Garraf. Esta actividad genera flujos energéticos y materiales los cuales a su vez son los productores de impactos sobre elThe use of pleasure boats is an extended activity in the coastal zone of el Garraf. This activity generates energetic and material flows which, in turn, are the producers of impacts on the port and its surrounding environment. In this article an evaluation of these flows (energy, water and residues) of our study system, is realized through chosen indicators applied for this purpose. These indicators are used, afterwards, to analyze the impacts that take place in the port boundries. Different improving proposals have been created from the results obtained in order to reduce the impacts due to the use and enjoyment of crafts, paying specia
