How to Improve the Biological Quality of Urban Streams? Reviewing the Effect of Hydromorphological Alterations and Rehabilitation Measures on Benthic Invertebrates

Urbanisation alters the natural hydromorphology of streams, affecting aquatic communities and ecological quality. Increasing efforts have been put into rehabilitation urban streams due to their importance for sustainability. Despite these efforts, many projects fail achieve improvement communities. This study aims provide specific recommendations enhance biological by reviewing: (i) impacts urbanisation climate change on stream hydrology, (ii) responses invertebrate assemblages alterations in hydrology morphology (iii) hydromorphological measures applied effect review found that commonly employed habitat heterogeneity enhancement (such as addition meanders, boulders, artificial riffles) are not enough improve On other hand, most effective those leading re-establishment hydrological patterns good water Ultimately, an integrated ecohydrological approach considers entire watershed its interactions between ecosystems anthropological activities is key managing rehabilitating streams.
