Abstract

The environmental reclamation of the terminal tract of Ravenna Candiano channel requires high improvement in quality characteristics of water, greatly polluted by harbour activity residues, by many outlets of urban drainage system, and by short replacement capacity supplied by tides in head channel at 12 Km from Adriatic sea. As firstly required the project provides to intercept sewers drainage systems, now carrying inside the "lake", and to convey these to discharge in Candiano, down a new embankment. In a second time Port Authority imposed as necessary the maintenance of port activity in head channel and a second option has been proposed, based on two stormwater tanks. The project is described in term of civil and electromechanics works and it is discussed such in treatment efficiency as in environmental impact. The present paper give a description of provided works and presents results in modelling forecasted effects on ecosystem level.
