Geomorphological map showing the fluvial terraces and erosional channels of the Moidieu, Septeme and Heyrieux corridors at the front of the internal moraine complex of the Lyonnais ice lobe and the main post-glacial fluvial and colluvium deposits found in the study area. 50m isolines of rock uplift come from numerical modelling of Quaternary erosion-induced alpine isostasy from Champagnac et al. (2007). Geodesic system used: WGS84, Projection system used: Lambert 93, Graticule units: Degrees minutes seconds.

Carte géomorphologique montrant les terrasses fluviatiles et les chenaux d’érosion des couloirs de Moidieu, Septeme et Heyrieux au front du complexe des moraines internes du lobe lyonnais ainsi que les principaux dépôts fluviaux post-glaciaires et de colluvion et/ou petits cônes de déjection locaux de la zone d’étude. Les isolignes 50 m d’uplift proviennent d’une modélisation de l’isostasie alpine induite par l’érosion quaternaire (Champagnac et al., 2007). Système géodésique utilisé : WGS84, Système de projection utilisé : Lambert 93, Unité des graticules : Degrés minutes secondes.
