**4. Conclusions**

The paper presents the method used to set up the Coastal Plan for the Venetian littoral. This method was based on a homogeneous approach at regional level consisting of a descriptive and a design phase and focused on an intensive use of a Coastal GIS database that stored both information and results, which were then organised into littoral cells and semi-cells.

The GIS also contains the sediment balance assessment obtained by analysing collected and modelled data, the accuracy of which is based on a compensation criterion. The ensuing erosion and coastal-flooding hazard, integrated with information on socioeconomic vulnerability, resulted in a priority index that highlighted the most critical areas. The information on relative sea level rise due to climate change and geodynamics are stored as they may have a relevant role for a correct design of the mitigation measures characterized by a long lifetime.

A noteworthy contribution of this paper is given in Section 2.2.1, which provides an example of a single mitigation strategy against erosion and coastal flooding for the region's valuable urbanized and non-urbanized low sandy coasts. The consistent application of this method to the Veneto Region produced measures that were globally accepted by stakeholders, and the plan was adopted by the Regional Authorities with regional decree DGR no. 898-14/06/2016. It is conjectured that the same approach may be adopted, with due modifications, in other low sandy beaches, as well.

After a general description of the main results for the Venetian coastal plan [23], the Rosolina (RO) coastline is described in detail and provided as an example case.
