Аллювий пойменный, русский
Отложения речных потоков, накапливающиеся на пойменной террасе при разливах реки. для пойменного аллювия характерно развитие определенных фаций: берего- вых песчаных валов, собственно пойменных отложений, пойменно-болотных глинистых гумуси- рованных отложений с прослоями и залежами торфа, старичных глинистых отложений и, наконец, присклоновых аллювиально-делювиальных отложений.

Alluvium, английский
- A general term for clay, silt, sand, gravel or similar unconsolidated material deposited by a stream or other body of running water.
- Gravel, sand, silt, soil, or other material that is deposited by running water. alm on drawings, abbr. for “alarm.”
- As incorrectly used by some drillers—the broken, earthy rock material directly below the soil layer and above the solid, unbroken bed or ledge rock. in a strict sense, alluvium should be applied only to soil and/or fragmented rock materials deposited by water upon land not permanently submerged beneath the waters of lakes and seas.
- Unconsolidated, clastic material subaerially deposited by running water, including gravel, sand, silt, clay, and various mixtures of these. compare - colluvium, slope alluvium. hp
- A deposit of sand, mud, etc., formed by flowing water.
- Detrital material of any grain size transported and deposited during
Floodplain, английский
- The low relief lands bordering a stream or river, common to the mature and old age stages of stream development. floodplains store excess water in times of high water, and excess sediments in times of low water. beware of building your dream house on a floodplain - they tend to get rather wet at irregular intervals.
