Synonym: Sand bar landscape; Heart-shaped sand bar landscape

A heart-shaped sand bar is a shoal in a riverbed or an underwater shoal that is exposed during the dry season. Its upstream portion is subject to flow erosion, while its lower part or tail is subject to deposition. As a result, the bar gradually moves downstream. When it grows to a large size, it is called a river island.
