    • n alluvion In modern legal use, an increase of land on a shore or a river-bank by the action of water, as by a current or by waves, whether from natural or from artificial causes. If the addition has been gradual and imperceptible, the owner of the land thus augmented has a right to the alluvial earth; but if the addition has been sudden and considerable, by the common law the alluvion is the property of the sovereign or state. By the law of Scotland, however, it remains the property of the person of whose lands it originally formed part. If witnesses could see from time to time that progress had been made, though they could not perceive the progress while the process was going on, the change is deemed gradual within the rule.
