What does sandbar mean?
A sandbar is a ridge or bank of sand deposited by moving water, most often in a river, estuary, or shallow coastal inlet. It can rise above the surface or remain just beneath the water, creating a hazardous obstruction for boats and a protected area of shallows behind it. The word is especially frequent in American English for the sand deposits that form at river bends and near stream mouths. In recreational contexts, people may refer to fishing from, wading across, or boating around a sandbar. The related term sandbank is sometimes used more broadly for any shallow sandy area, while shoal can refer to shallows formed by sand, rock, or mud. Sandbar is consequently a precise term when the material or shape of the obstruction matters.
nounA natural or artificial ridge or bank of sand deposited in a river, estuary, or along a shoreline, often forming a shallow obstruction in the water. The term is especially common in North America for sandbars that form in rivers or near the mouths of streams.
- A ridge, mound, or elongated deposit of sand formed by flowing water, especially in a river, estuary, or coastal inlet.
- A shallow area of sandy water separated from deeper water by such a deposit.
"The river dropped sharply after the rain, leaving a broad sandbar across the shallows."
"Fishing boats anchored behind the sandbar as the tide began to fall."
"After the drought, only a narrow channel remained between the sandbars."
The usual plural form, especially for individual deposits or ridges of sand.
"The boat grounded on one of the sandbars near the inlet."
A sandbar can turn a deep river into a shallow obstacle—and can also create a sheltered channel that boats use as a shortcut.
