La moyenne Garonne a vu sa morphologie et sa dynamique hydro-sédimentaire durant le XXe siècle se modifier de manière significative, avec la contraction de la bande active et l’incision de son chenal. Cette thèse se propose d’analyser les ajustements verticaux du cours d’eau depuis 1830 et la dynamique d’évolution des seuils rocheux mis à l’affleurement sous l’effet de l’incision. L’étude se fonde sur une approche géohistorique et une approche de terrain, à trois échelles spatiales : (1) le linéaire de la moyenne Garonne, (2) trois tronçons et (3) les seuils inscrits dans les tronçons. A l’échelle du linéaire, trois phases d’ajustements sont identifiées : une première phase (1830-1860s) d’exhaussement (1,9 cm.an-1) et d’élargissement, une s...
