Flood leash surveys in the Landes department

History of flood leashes in the Landes department. Flood leashes are traces left by river water level during flooding. Two other layers complete this table: L_AZI_CRUE_FORTE_S_040 and L_AZI_CRUE_FAIBLE_S_040 __Origin__ For municipalities without a natural risk prevention plan (PPRN), the route according to several methods: — flood leash surveys and calculation of the slope line d'water joining these points, according to a survey by a surveyor. The curve was then carried over to a parcel plane. — geomorphological study determining the potentially flooded sector. For municipalities with a PPRN, the curve follows the external path of the zone d'aira. This information is available in an attribute of the table. __Partner organisations__ DDTM Landes __Links annexes__ * [XML metadata view](http://ogc.geo-ide.developpement-durable.gouv.fr/csw/all-dataset?REQUEST=GetRecordById&SERVICE=CSW&VERSION=2.0.2&RESULTTYPE=results&elementSetName=full&TYPENAMES=gmd:MD_Metadata&OUTPUTSCHEMA=http://www.isotc211.org/2005/gmd&ID=fr-120066022-jdd-687e22e2-9892-4978-a958-80c97a41ff2e) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/30b8dbddcfcfec0fb0166c820db7aa3ecf49bcbd)
