batture 1. n., The gradual raising of the bed of a river or body of water by the accumulation of solid matter such as silt, soil, or gravel. 2. n., That portion of the bed of a river or body of water which has been raised by the gradual accumulation of solid matter. When accumulated matter has reached the point where it extends above the surface of the water and is therefore no longer part of the bed, it is still sometimes referred to as batture. However, the terms alluvion (for the process) and alluvium (for the land) are more specific and appear to be preferred. SEE ALSO alluvion; alluvium.
accession to real property n., The addition to real property by growth, increase, or labor, which may take place either in a natural way or in an artificial way (e.g. land gradually deposited on the bank of a stream by imperceptible means). Title to real property can be acquired by accession to real property. SEE ALSO accretion; alluvion.
