Properties along river banks

A farmer wakes up one day and half his riverside land is simply... gone. Meanwhile, his neighbor across the river somehow has more land than before. What's the law on this? Can a river really just redraw property lines in the Philippines?
Turns out, yes โ and the law has two very different answers depending on how it happened.

Under the Civil Code, land near rivers can change ownership through natural forces in two distinct ways: alluvion (gradual buildup of soil) and avulsion (a sudden, violent transfer of a known chunk of land). They sound similar, but the legal consequences are completely different โ one gives you free land, the other puts your original land on a countdown.

Article 457 of the Civil Code says landowners next to a river automatically own the soil that gradually and imperceptibly builds up along their bank. For this to apply, courts look for three things: the deposit must be slow and unnoticeable day-to-day, it must be caused naturally by the current, and the new land must be adjacent to the existing riverbank property. No paperwork, no payment โ the added land simply becomes part of your title by operation of law.
The rationale: since your land is the one at risk of erosion and flooding from the river, you're also the one entitled to what the river gives back.
But there's a catch โ if you dump soil yourself, dam the current, or otherwise engineer the buildup, it isn't alluvion. That's unlawful reclamation, and it won't transfer ownership to you.

Article 459 covers the opposite scenario โ a flood or strong current suddenly tears off a recognizable portion of your land and dumps it onto someone else's property, or even across the river entirely. Here's the twist: you don't lose it outright. The law says you keep ownership of that detached portion, as long as you can identify it and physically remove or reclaim it.
โณ ๐ง๐ต๐ฒ ๐ง๐๐ผ-๐ฌ๐ฒ๐ฎ๐ฟ ๐๐น๐ผ๐ฐ๐ธ ๐ฌ๐ผ๐ ๐๐ฎ๐ป'๐ ๐๐ด๐ป๐ผ๐ฟ๐ฒ
This is the part most landowners don't know: you only have two years to claim and remove that avulsed portion. Miss the window, and it's absorbed into the land it landed on. Courts have also made clear that if you can't prove the change was sudden, the presumption defaults to gradual accretion โ meaning the burden of proof is on you to show it was avulsion, not alluvion, if you want to reclaim it.
So back to our farmer: whether he still owns that missing half of his land depends entirely on whether it eroded away gradually (in which case it's now legally his neighbor's) or was torn off suddenly and identifiably (in which case he has two years to act). Same river, same missing land, two completely different outcomes.
