三角洲,即河口冲积平原,是一种常见的地表形貌。江河奔流中所裹挟的泥沙等杂质,在入海口处遇到含盐量较淡水高得多的海水,凝絮淤积,逐渐成为河口岸边新的湿地,继而形成三角洲平原。三角洲的顶部指向河流上游,外缘面向大海,可以看作是三角形的“底边”。

「三角洲」这名词翻译自英文delta。英文delta即希腊文Δ的转写。希腊文含义源自三角洲的形状像“Δ”(三角形),有人认为这就是字母“Δ”的象形起源。

The Ganges Delta in India and Bangladesh is the largest delta in the world and it is also one of the most fertile regions in the world.

A river delta is a landform that forms from deposition of sediment carried by a river as the flow leaves its mouth and enters slower-moving or standing water. This occurs where a river enters an ocean, sea, estuary, lake, reservoir, or (more rarely) another river that cannot transport away the supplied sediment.
