Display Field: cours_eau
Type: Feature Layer
Geometry Type: esriGeometryPolygon
Description: Les 'fractions de bassins versants' représentent le découpage élémentaire des bassins versants (BV) de cours d'eau, délimités selon la topographie.
A chaque surface correspond un exutoire de BV, positionné selon les règles suivantes:
- à chaque confluence de cours d'eau;
- à chaque changement d'état le long du cours d'eau, si une surface contributive significative peut-être définie.
Les limites des BV ont été digitalisées manuellement à partir des lignes d'écoulement préférentiel, obtenues automatiquement à partir du MNT.
Remarques importantes:
- s'agissant de BV toopographiques, l'écoulement des eaux dans les réseaux de canalisation n'est pas pris en considération;
- les lignes de structure non naturelles (tels que murs, routes, etc.) ne sont pas prises en considération. La pertinence des BV en milieu urbain est ainsi amoindrie.
