This paper deals with the assessment of the environmental effects of the channelization, which has been monitored throughout the first year after completion of the project. Although the city is effectively protected against extreme hydrological events, the natural values of the river have been altered. The hydraulic conditions generated in the channelized section, the complete elimination of the riparian vegetation, the induced homogeneity of the morphological characteristics of the riverbed, and the worsened water quality joined with the uncontrolled direct wastewater disposals all contribute to question the success of the project from the environmental point of view.
