Alluvium - ndiwo mugumisiro mabasa mvura Rwako

Chii alluvium? Tsanangudzo iyi izwi anogona kupiwa nenzira dzakawanda. Zvose zvinoenderana ndiani nyaya iyi. Nokuti mudzidzi, nokuti mudzidzi, nokuti vemba, chive nyore munhuwo zvake tsananguro kunganzwika zvakasiyana.

Zvichida mumwe munhu kanenge kamwe muupenyu zvinoitika kurwizi. Uye kana zvaitika muchirimo, panguva mafashamo, angadai vakacherekedza guru mari siyana nezvinhu (ibwe, zvimedu pamatombo, boulders, jecha, silt, muti uye shrub mapazi, zvakanaka, kana asiri zvakasiyana nevanhu masarasara) anotinhwa rwizi nomurwizi . Pfungwa iyi zvose ndiye alluvium.

Saka, alluvium - zvose kuti kunounza rwizi? Kwete, kwete chaizvo. Zvadaro, pamwe, alluvium - chikamu mugero iyo rwizi kuita mubereki wake dombo? Kwete.

Zvesayenzi tsanangudzo rokuti

Zvakanaka, zvino isu kumupa zvose zvakafanana tsananguro nesayenzi. Alluvium - emadhaka iri rakachengetedzwa dzemvura zvinosanganisira kushambidzwa uye arongwe detrital nyaya uyewo makemikari nyaya. Shoko pacharo rinobva muchiLatin alluvio, zvinoreva "hwaishanda", "alluvium".

Alluvium mapani uye nenzizi gomo

Pane mhando mbiri mikuru alluvium, izvo zvinobva zvikurukuru pamusoro tectonics uye kwenzvimbo, apo rwizi runoyerera. alluvium ichi gomo uye nokumapani nzizi.

nzizi Alluvium gomo

River mumakomo zvinowa- dzinoratidzwa guru chokubuda yevanhu deposits acho kazhinji mabwe mavhu. Kuramba kwazvo uye akapfava matombo havana nguva yokudziyira rwizi uchitora nomurwizi.

nzizi Sedimentation gomo dzinoratidzwa anotevera zvinhu:

• Inoitwa zvinonyadzisa nemarara, izvo rikunde shingle;
• siyana chicherwa sezvamunoita zvimedu;
• murombo Sorting mashoko;
• hakuna stratification yakajeka.

Alluvium pamapani nenzizi.

Pamapani nzizi maduku iyerere zvazvingava uye, naizvozvovo, havagoni kutakura pamusoro madaro marefu zvinonyadzisa zvimedu.

Nokudaro vachikonzera nokumapani nzizi dziri kuri mune dzimwe zvairatidza:

• melkooblomochnogo panofanira zvinhu iro hunodzorwa jecha uye jecha loam;
• zvakakwana homogeneous chicherwa sezvamunoita;
• Sorting zvakanaka zvinhu;
• kuvapo zvinonyadzisa muchinjikwa zvekufuga, vakapfuura munzvimbo duku muchinjikwa zvekufuga.

The zoning yomurwizi alluvium uye ayo unhu

Zoning ndizvo kuti chero dzinongoitika chinonakidza kana chinhu. Kunyange zvazvo ari alluvial ivhu riri shoma raidudzwa kupfuura rumwe, uye dzinonyanya zvinoriumba constituent rinongova alluvium. Izvi, zvisinei, harirambidzi matambudziko zoning pamusoro alluvium, achinyanya ayo chicherwa sezvamunoita uye acidity.

Zvisinei, chikuru rwizi wayo floodplain, kashoma raidudzwa zoning alluvial deposits.

Paavhareji, nemadhaka nzvimbo dziri kuchamhembe alluvial nevhu yemanyorero vari acidic, dzinoratidzwa kusavapo carbonates uye asiri sesaline. With mberi kumaodzanyemba, iri kupfuura dzisinganayi dzoga, vanova kwazvakarerekera pakutanga, uye zvino ane alkaline maitiro, vaine saturation pamwe carbonates.

Delta, floodplain, oxbow uye mugero alluvium

Alluvial deposits mu nokumapani nzizi dziri akaoma uye zvawanda. Naizvozvo, hunhu kwemvura, uye nzvimbo dzavo mari alluvial deposits akakamurwa murwizi mubhedha, kuti Delta, floodplain uye oxbow.

Deltaic alluvium achiumbwa deltas uye vaine jecha-dzevhu sezvamunoita.

Channel alluvium akaumba munzizi uye rinoumbwa kunonyanya jecha uye coarser Marara, zvakadai boulders, hurungudo uye mavhu. Vari inoumbwa jecha mbariro, akasvipira mumwe uye zvitsuwa kurwizi.

Floodplain alluvium akaumba panguva mafashamo uye rine zvakasiyana-siyana loam, jecha rakanaka uye ivhu akapfuma Organic.

Oxbow alluvium rakachengetedzwa pamusoro pasi oxbow madhamu uye chinosanganisira silt zvakawanda makemikari nyaya.

Alluvial deposits vari rinoparadzirwa pasi pose. Long sezvo iri kukura kwavo akatanga kubuda ose makuru nyika yekare pundutso dzakadai muIjipiti yekare Mumupata murwizi kana Mesopotamia yekare mumipata Tigirisi uye Yufuratesi.

In zvokurima nyika dzakawanda maberekero ano zvenyika dziri munzvimbo floodplain alluvium. It kakawanda ine deposits zvicherwa, uye kunyange zvicherwa zvinokosha.
