If a state-owned watercourse forms a new course by abandoning its old bed, the riparian owners may acquire ownership of this old bed, each in his or her own right, up to a line assumed to be drawn through the middle of the watercourse. The price of the old bed is fixed by experts appointed by the president of the court in the location of the place, at the request of the competent authority.
If the riparian owners fail to declare, within three months of the notification made to them by the competent authority, their intention to make the acquisition at the prices fixed by the experts, the old bed is alienated according to the rules governing alienations of the domain of public persons.
The price from the sale is distributed to the owners of the land occupied by the new course as compensation, in proportion to the value of the land removed from each of them.
