(河口;入海口水域)指河流汇入海洋(或大湖)处受潮汐影响的水域,常为咸淡水混合、生态丰富的区域。(也可泛指较宽阔的河口水域)
The river widens into an estuary near the sea.
这条河在靠近大海处变宽,形成河口水域。
As urban growth increased, pollution and dredging began to disrupt the estuary’s delicate balance of tides, sediment, and wildlife.
随着城市扩张加剧,污染与疏浚开始破坏河口区域在潮汐、泥沙与野生生物之间的脆弱平衡。
Estuary 源自拉丁语 aestuarium(“受潮汐影响的水域/河口”),与 aestus(“潮汐、涌动、热浪般的起伏”)同源;后经古法语 estuaire 进入英语,大约在16世纪开始常见。
