A river delta is a triangular landform created by the deposition of the sediments that are carried by the waters of a river, where the river merges with a body of slow-moving water or with a body of stagnant water.
Deltas are wetlands that form as rivers empty their water and sediment into another body of water, such as an ocean, lake, or another river. Although very uncommon, deltas can also empty into land. A river moves more slowly as it nears its mouth, or end.
A delta landform is a sophisticated depositional feature that typically occurs at the mouth of a river. By definition, the mouth of the river is where the river drains into a water body such as lake, ocean or sea, leading to reduction of the rivers capability to transport sediment any farther.
DELTA meaning: 1. an area of low, flat land, sometimes shaped like a triangle, where a river divides into several…. Learn more.
A river delta is a low-lying plain or landform that occurs at the mouth of a river near where it flows into an ocean or another larger body of water. Deltas' greatest importance to human activities, fish and wildlife lay in their characteristic highly fertile soil and dense, diverse vegetation.
A river delta is a wetland area created when a river empties into another body of water, such as another river, lake or ocean, or on rare occasions into a land basin. These areas tend to fluctuate with tides and precipitation rates and periods of flooding are not uncommon in deltas.
The presence of a delta represents the continuing ability of rivers to deposit stream-borne sediments more rapidly than they can be removed by waves and ocean currents. Deltas typically consist of three components.
A delta is a body of sediment deposited at a point along a body of water where a sediment-transporting channelized flow of water enters the water body.
Deltas, with their fan-shaped structures, form when rivers discharge silt into a lake, ocean, or sea. This creates productive, dense wetlands rich in biodiversity that support ecological and human communities.
A delta is a deposit of sediment at the mouth of a river that accumulates as the river flows into a standing body of water such as a lake or ocean. Because sediment tends to be rich in nutrients, deltas become fertile wetlands inhabited by diverse wildlife.
