Atlas of flood zones (AZI) of the Loire Estuary — linear embankments

The data of this layer represent the linear embankments (like d' linear infrastructures, dikes or other embankments of type talus, slabs...) located in the alluvial plain of the Loire. They have been identified with the precision field numerical model, the Litto 3D and supplemented by field visits, databases provided by the GIP Loire Estuaire and l' analysis of maps and ancient aerial photographs. L' all embankments n' is not represented on this layer. Only the most important embankments that can have impacts on the flows are represented on this layer. L' scale of realisation of the l'atlas (1/25000 to 1/10000) does not take into account any small local embankments that can be made at the point of #x27; scale of small plots. This layer identifies the linear embankments located in the alluvial plain of the Loire but does not specify their impact on the modification of natural flows.
