ROR Areas with Potential Significant Flood Risk EU2018 lines (Flood Risk Directive) RWS

Areas with Potential Significant Flood Risk in the Netherlands contains the designated areas from the flood risk report in the Netherlands, 2018. Preliminary flood risk assessment and designation of potentially significant flood risk areas under the European Flood Risks Directive (ROR) 2nd cycle 2016 to 2021. The areas are designated on the basis of the following principles. Areas are distinguished according to the four separate river basin districts. Areas are divided into four types (A, B, C, D) of floods that reflect the difference in protection, as well as the diversity of responsibilities and roles of relevant governments. The boundaries of the areas are based on the extreme limits of the potentially floodable area, as determined on the basis of simulations from the national flood database. For the primary flood defences, the area has been supplemented to the high ground line. The Rijkskanaaldijken are part of the designated areas. In total, 14 GPSOR are awarded in the Netherlands. Areas of Type D are not present in the Eems and Scheldt river basins. There are areas that can flood both from the main water system (B) and the regional water system (C).
