Description

Chisseaux (Indre-et-Loire)

Le Port Olivier et l'écluse.

Au XIXe siècle, le Cher est canalisé depuis Noyers-sur-Cher jusqu'à Saint-Avertin.

La commune, est pourvue en 1830-1840 d’un barrage à aiguilles sur le Cher, d'une écluse rive droite.

L'écluse mesure 35 m de long sur 5,15 m de large. Le barrage est composés d'aiguilles en bois de 2,50 m de haut sur 7 cm de large et d'un déversoir sur la gauche. Le 7 juin 2010 le déversoir de Chisseaux tue 2 navigateurs qui tentaient de franchir le barrage. Le dangereux phénomène de rappel* est trop souvent méconnu.


  • Le rappel est une : "Perturbation dangereuse dans l’écoulement de l’eau pouvant survenir en bas d’une chute d’eau. Cette perturbation entraîne une émulsion de l’eau, un mouvement de surface qui ramène l’eau vers la chute, un affouillement qui creuse une excavation au pied de la chute. Les barrages artificiels ou des chutes naturelles peuvent avoir un rappel à leur pied ce qui interdit totalement leur franchissement."
