This app allows to visualize and compare the flooding scenarios due to both the Relative Sea Level Rise -RSLR- (left side of the map) and the combined effects of the RSLR, astronomical tide and storm surge (right side of the map) with regard to selected study areas of the SAVEMEDCOASTS-2 project. Use the panels below to set the input parameters and then click on the Show on map button to see the scenarios on the map and their main features in the lower panels. By moving the map divider horizontally, you can compare the scenarios given the input parameters.
Warning: please note that the following maps represent flooding scenarios without considering any adaptation or protection systems (e.g. MOSE in the case of Venice Lagoon). Disclaimer

Glossary:
IPCC = Intergovernmental Panel on Climate Change
AR5 = IPCC's Fifth Assessment Report
RCP = Representative Concentration Pathway
RCP2.6 = low-emissions scenario (mitigation)
RCP8.5 = high-emissions scenario ("business as usual")
SLR = Sea Level Rise
VLM = Vertical Land Motion (negative if subsidence, positive if uplift)
HAT = Highest Astronomical Tide
MWE = Maximum Water/Flood Elevation, calculated as RSLR + HAT or the overtopping discharge of sea defences, if it occurs.
Area 0 = Potentially flooded area due only to RSLR
Area 1 = Potentially flooded area due to RSLR, highest astronomical tide and storm surge
