Geographical distribution of the share of agricultural land in floodplain areas, calculated by functional elementary catchments (FEC)

Metadata

information.png Methodology:

Area of agricultural land within the potential flood-prone areas was calculated as an average of the years 2011 to 2013. The share of flood-prone area covered by agricultural area was calculated using following formula:
area of MAES agricultural (cropland and grassland) area within FEC floodplain / potential flood-prone area extent within FEC (rivers, estuaries and other "blue areas" are excluded from this calculation) *100

Based on data

Data EEA potential flood-prone area extent The EEA potential flood prone area extent delineates the area that is flooded once every 100 years, i.e. the probability of flooding is 1% assuming that flooding is unrestricted. The potential flood prone area is comprised of the river channel and floodplain. In reality, the floodplain is split into an active floodplain where flooding still occurs, and former floodplain where flooding is restricted due to flood protection. The former floodplain could be flooded again either if a flood exceeds the capacity of flood protection, or if factors that control the presence of water were removed. These factors include channel and floodplain morphological alterations as well as structural flood protection measures. The spatial coverage of the data set is EEA39 countries.
Data Copernicus Land Monitoring Service - Riparian Zones Riparian zones represent transitional areas occurring between land and freshwater ecosystems, characterised by distinctive hydrology, soil and biotic conditions and strongly influenced by the stream water. They provide a wide range of riparian functions (e.g. chemical filtration, flood control, bank stabilization, aquatic life and riparian wildlife support, etc.) and ecosystem services. Three complementary product groups provide detailed information on the state and characteristics of riparian zones across the EEA member and cooperating countries: Land Cover / Land Use (LCLU), Delineation of Riparian Zones (DRZ), Green Linear Elements (GLE).
Data European catchments and Rivers network system (Ecrins) Version 1, Jun. 2012 - Ecrins is acronym for European catchments and Rivers network system. It is a geographical information system of the European hydrographical systems with a full topological information. Ecrins is a composite system made from the CCM developed by the JRC, Corine land Cover, WFD reporting elements, etc. It is organised from a layer of 181,071 “functional elementary catchments (FECs)” which average size is ~62 km2, fully connected with explicit identifier (ID) relationships and upstream area. Catchments are grouped as sub-basins, river basin districts (actual and functional to meet hydrographical continuity). The catchments are as well organised according to their sea shore of emptying to meet Marine Strategy delineations. Catchments are drained by 1,348,163 river segments, sorted as “main drains” (connecting together the FECs) and secondary drains (internal to a FEC). river segments mimic the natural drainage, however fulfilling the topological constraint of “0,1 or 2 upstreams, single or 0 downstream”. Each segment is populated with distance to the sea, to ease further processing. They are connected to elementary catchments and nodes documented with altitude. Segments are as well documented with a “dummy river code”, fully populated that earmark each segment with the most distant to the outlet in each drainage basin and, everywhere this has been possible, with a “true river” ID based on river naming. A layer of lakes and dams has been elaborated. Lakes polygons (70,847) are taken from Corine Land cover , WFD Art. 13 and in some cases, from CCM “water layer”. Lakes inlets and outlets are set with the segment ID and where relevant, the dams making the lake is documented. All lakes which depths and volume was found have been updated. Version 1.0 here presented still contain some topological errors (e.g. incorrect segment branching), because inaccurate geometry. They are noted and a correction procedure is underway.
