Project summary

Edit project overview to modify the project summary.

The Consorzio di Bonifica Acque Risorgive (drainage authority) is located within the pumped drainage landscape of the Venice Lagoon. The Consorzio was involved in a big project aimed at developing a catchment strategy to reduce nutrient loads entering the Venice Lagoon from its rivers. To achieve this goal, the Consorzio planned a major river restoration project for the Zero River, which drains into the lagoon. The main restoration actions carried out regarded: banks widening, increase of aquatic vegetation on river terraces, creation of lateral and inflow wetland (ponds and lakes) and creation of wooded riparian area irrigated by river water. Within this project a pilot experimental system was built along the Zero River, to evaluate in particular the buffering efficiency of the wooded areas on non-point pollution sources of nitrogen. On the experimental site, represented by a newly-established riparian woodland, the hydrology of the woodland is totally regulated through a series of pumps which irrigate the woodland with water coming from Zero River, through a series of parallel ditches (irrigation and drainage ditches). The results of this study provided interesting suggestions for improving the management of riparian buffer zones.
