sand bank
Shallow water hazard
A sand bank is a ridge or mound of sand formed by currents in a river, sea, or lake.
Sand banks often lie just below the water's surface, creating hazards for boats: The ship ran aground on a sand bank.
They shift with tides and weather, making navigation unpredictable.
Also written as one word: sandbank.
