Short answer. The abandoned bed belongs automatically to the owners whose land the new course now occupies, in proportion to what each of them lost. Owners adjoining the old bed have only a right to acquire it by paying its value, which cannot exceed the value of the area taken by the new bed.
What the law says
River beds which are abandoned through the natural change in the course of the waters ipso facto belong to the owners whose lands are occupied by the new course in proportion to the area lost.

The bed goes to whoever lost land to the river
The allocation is a trade, not a windfall. The abandoned bed ipso facto belongs to the owners whose lands are occupied by the new course in proportion to the area lost. The river takes from one set of owners and the law compensates that same set with what it left behind. Ipso facto means the transfer happens by force of the article itself, without a court order or a conveyance, at the moment the change occurs. And where several owners lost land, they share the old bed in the ratio of their losses rather than in equal parts.
Why the neighbours of the old bed do not simply take it
This is the assumption most readers arrive with, and it is the wrong one. Owning land beside a channel that has dried up gives you no automatic title to the ground the water vacated. What the article gives adjoining owners is a preferential right to acquire the bed by paying the value thereof — a right to buy, exercised against those to whom the bed already belongs. It is worth having, because it lets the land beside the old channel be consolidated with it, but it is not ownership and it is not free.
The price is capped
The article limits what the adjoining owner can be charged: the value shall not exceed the value of the area occupied by the new bed. That ceiling keeps the exchange proportionate. Those who lost land to the new course are meant to be made whole, not enriched, so they cannot hold out for whatever the dry bed might fetch in a rising market. Two valuations therefore matter in any dispute of this kind — the value of the abandoned bed and the value of the land the river now covers — and the lower of them sets the outer limit of the price.
The condition everything depends on
The rule applies to a bed abandoned through the natural change in the course of the waters. A channel altered by works, diversion or engineering is not what the article contemplates, and the answer for such a case does not come from here. So the first facts to establish are physical and chronological: when the river moved, whether anything was built or excavated that moved it, and where the banks stood before. Old survey plans, dated aerial or satellite imagery, and the titles of every affected parcel are the working documents.
