A sandbank is a raised area of sand in a river or in the sea, built up by moving water. It may hide just under the surface or stick out like a low island. Boats can get stuck on it.

A sandbank沙洲 is是 a raised area of sand一塊隆起的沙地 in a river or in the sea在河裡或海裡 built up by moving water由流動的水堆積而成 It它 may hide just under the surface可能剛好藏在水面下 or或 stick out like a low island像座低矮的小島一樣露出來 Boats船隻 can get stuck on it可能會擱淺在上面

English also says sandbar for the same kind of ridge; sailors may say shoal when they mean a shallow patch that can catch a boat. Bank here is the 'raised ground' sense, as in riverbank — not a place for money.

Though actually, speakers are a bit loose: a huge dry stretch the tide leaves behind, a thin ridge, and a shifting patch in a river mouth may all get called a sandbank. It is an ordinary geography and sailing word, not a fancy one.
