                  <gco:CharacterString>1) Données d'entrée : Lmax issu des stratégies locales, trait de côte 2014 et résultats de l'analyse DSAS.     

2) Traitement : projection du trait de côte à l'horizon 2025 en utilisant le champ ""Tx_11ans""  

3) Contenu : Taux_evol (taux d'évolution issus des stratégies locales); Morphologi (type de morphologie de la côte);Troncon (numéro du tronçon du TDC selon les caractéristiques géomorphologiques);Commune; Secteur (lieu-dit/plage);Larg_Max (Lmax issu des stratégies locales); CoeffSL_10 (coefficient multiplicateur pour mise à jour du Taux_evol à l'horizon +10ans suite à l'étude du CASAGEC); CoeffSL_30 (coefficient multiplicateur pour mise à jour du Taux_Evol à l'horizon +30ans suite à l'étude du CASAGEC); Tx_11ans (Taux_evol x coeffSL_10 x 11ans); Tx_36ans (Taux_evol x coeffSL_30 x 36ans); Lmax_10 (Lmax en 2025 issu des stratégies locales); Lmax_30 (2,5 x Lmax_10 d'après les stratégies locales); Recul_2025 (Tx_11ans + Lmax_10); Recul_2050 (Tx_36ans + Lmax_30); INCERT_SEU (seuils d'incertitude sur une échelle de 1 à 5 - 1=faible incertitude ; 5=forte incertitude)
