Sandbars can be classified into submerged sandbars that lie underwater and emerge during low tide, exposed sandbars that are visible above water at all times, and offshore sandbars that are found further out to sea. Other types include crescentic sandbars that curve in a crescent shape, recurved sandbars with a concave shoreline, and straight sandbars that run parallel to the coast.

longshore currents for example ,often deposit sand along shorelines,the sand builds up to form sandbars
Sandbars occur when sediment is deposited by water, usually in shallow areas such as rivers or coastlines. They can form due to changes in water flow, wave action, or changes in sediment supply. Sandbars are dynamic features that can change over time due to natural processes.
