La courbure de cette plante aquatique indique bien le changement de direction de l'eau dû à la présence de la pile dont on voit l'étrave à gauche de l'image.
Cette pile du pont rétrécit le lit de la rivière et oblige donc le courant à le contourner.
Ces plantes aquatiques indiquent qu'à cet endroit le courant oblique légèrement vers la gauche.
