The relative amount of these two kinds of water varies greatly from one kind of rock or sediment to another, even though their porosities may be the same.(這兩種水的相對含量在不同的巖石或沉積物之間差異很大，盡管它們的孔隙率可能是相同的。)

Others point out that decreased sediment loads will likely lead to erosion of downstream riverbanks and the Mekong Delta.(其他人指出，泥沙負(fù)荷的減少可能會導(dǎo)致下游河岸和湄公河三角洲的侵蝕。)

The more poorly sorted or the more tightly compacted a sediment is, the lower its porosity and permeability.(沉積物分選越差或壓實(shí)越緊，其孔隙度和滲透率就越低。)

Also, things like the damming of rivers has caused increased sediment production, not to mention the addition of more carbon dioxide and methane in the atmosphere.(此外，河流筑壩等工程也增加了沉積物的產(chǎn)量，更不用說大氣中二氧化碳和甲烷的增加。)

So sediment is transported and then deposited and it forms layers on the Earth's surface over time.(所以沉積物被運(yùn)輸，然后沉積，隨著時間的推移，它在地球表面形成了層。)

Many organisms that die in the sea are soon buried by sediment.(許多在海里死亡的生物很快便被沉淀物掩埋。)

This idea was modified in the late twentieth century, when geologists and oceanographers examining oceanic sediment found fossil evidence of warming and cooling of the oceans.(在20世紀(jì)后期，地質(zhì)學(xué)家和海洋學(xué)家在研究海洋沉積物時發(fā)現(xiàn)了能夠證明海洋變暖和變冷的化石，并修正了這一觀點(diǎn)。)

When snorkeling, do not touch the coral or stir up sediment, as these actions can damage the reef's fragile ecosystem.(潛泳的時候，不要碰珊瑚礁或者攪動沉淀物，因為這樣做可能會破壞珊瑚脆弱的生態(tài)系統(tǒng)。)

The plant functions as a stabilizer and a sediment trap and as a nursery area for estuarine fish and shellfish.(該植物可作為穩(wěn)定劑和沉積物捕集器，并可以作為培育河口魚類和貝類的地方。)

Much of the water in a sample of water-saturated sediment or rock will drain from it if the sample is put in a suitable dry place.(如果把水飽和的沉積物或巖石樣品放在合適的干燥的地方，樣品中的大部分水將從中流出。)

用作名詞(n.)

The sediment of the water settled and it was clear.
水中的雜質(zhì)沉淀后，水變清澈了。

A claret bottle with half an inch of sediment in it.
