, 6a montre l'écoulement unidirectionnel simple selon la descente la plus raide dans des secteurs à forte pente. La figure A.6b montre l'écoulement en nappe en s'étendant vers les secteurs en aval quand la pente est moins forte. La figure A.6c montre le flux qui s'étale dans tous les sens
, Le facteur de rugosité (IR) présenté près (Mark, 1975) est lié à cette mesure
, 1 nous pouvons observer la liste de missions LiDAR terrestre réalisées à Draix. Les éléments descriptifs de chaque mission montrent l'évolution de la technique. Un premier essai réalisé en novembre 2006, sans repérages terrain, nous a montré la potentialité de cet appareillage pour son utilisation dans la validation des MNT drone fins
, nous avons effectué des essais avec repérages terrain amovible mais d'une taille non adéquate pour la distance à l'objet scanné Ensuite, des scans avec repérages terrain amovible et de taille adéquate ont été achevés, 2007.
, afin d'étudier les mouvements de terrain. Nous avons aussi effectué des scans pour l'analyse de précision sur une série des tôles avec de formes géométriques connues, ainsi que des scans pour l'évaluation de l
, LiDAR terrestre pour l'étude de changements morphométriques de versants, par altération superficielle et érosion, ont commencés en mars 2008, mais cette fois-ci avec les repères terrain fixes. L'objectif était d'évaluer la méthode de recalage numérique des scans LiDAR terrestre diachroniques avec l'utilisation des repères de terrain fixes
