Mobu Alluvial: characterization le tlhophiso

ke eng mobu alluvial? Litšobotsi tse le tlhophiso ea mobu tsena le tla fuoa ke re sehloohong sena. Lebitso la mobu tsoa lentsoe Latin alluvio, e bolelang "alluvium", "ho etsa hore". Sena se hlalosa hore na etymology le tšimoloho ea mobu. Lia bōptjoa linōka inwash, e entsoe ka likaroloana tsa mafika hore linōka lipalangoang tloha finyellang e ka holimo ho e ka tlaase 'me sa tloha litlhokoa nakong meroallo. Joalo tse bonahalang e le e bitsoa alluvium. O nonneng haholo ka lebaka la nōka larileng liminerale e seng feela, empa hape mesaletsa likokoana-hloko ea limela le liphoofolo. Classification ea mobu e pharaletseng alluvial. Ka mor'a hore tsohle, linōka na puso ea bona hydrological. From eo, ba teng nako le nako ka libotlolong le tšoanang le mabaka a mang, ho ipapisitse le seo mobu ba theha libakeng tse ling. A re ke re sheba mefuta eno ya mobu le eena.

Ke seo floodplain le terraces

E mong le e waterway ka makholo a lilemo butle empa butle-butle fetola le sebopeho sa naha ya naha haufi. Le ho feta nōka, le le matla haholo ho feta ke tshebetso ena. O lekeha lebōpong le. From le kanaleng ena e ba sephara. Empa ho phaella ho khoholeho ea mobu e lebōpong la leoatle, 'me ho na le ke tshebetso tebileng. Nōka ea fokotsa ho ka tlase betheng ea hae. Tshebetso ena e ka bapisoa le kopo ya maqeba incision. Tse tebileng ba thipa longoa, e khōlō le e hanyetse ea metshetshe letlalo. Empa ka papiso ena e tlas'a maemo haholo. Haeba u sheba le nōka le libanka ea eona e leng karolo tse tshekaletseng, u ka khetha le kanaleng, floodplain le terraces. Le pele tsohle e hlakile - sena ke sebaka seo ho sona metsi a phallang.

Litšobotsi tsa mobu alluvial

mofuta ona wa ea mobu o etsang liphesente tse tharo feela tsa naha. Empa o ho nkoa e nonneng ka ho fetisisa. Mora mobu alluvial - ha e le hantle, nōka ea seretse, e nang le liminerale. Ka lebaka leo, mobu tsena ananeloa ka temo. Hopola hore kaofela ha tsoelo-pele batho ba pele ba hlaha le ntshetswa pele ka linoka: Nile, Yan Tszy le Yellow River, ea Tigris le ea Eufrate. linokana tsena ile a fa batho ba mobu o nonneng leo ho hōla ya lijalo morui, esita le boemong ba khale tsa ho lema.

Ka mobu floodplain alluvial teng makhulo, e leng makhulo molemo ka ho fetisisa le makhulo fana likhomo fepa bakeng sa ea mariha. Ka terraces noka ntshetswa viticulture. Ka thuso ea Reclamation libakeng moru le tloaelo ea raese le ntseng le hōla. Floodplains ke tsa bohlokoa le ea ho tsoasa litlhapi. Ha e le hantle, nakong ea likhohola e na le fetisa spawn le bakang mocha.

Classification ya mobu alluvial

A tsobotsi bath ya mobu tsena ke hore ba ka potlako hōla. Haholo-holo e ama libakeng la lithoteng moroallo. Ba bang ba linōka moroallo o hlahellang teng mathoasong a selemo ha lehloa le qhibiliha, ba bang ba - mariha (Mediterranean tlelaemete), oa boraro e - ka ea lehlabula, ka nako ya lipula lipula. Empa puso ea hydrological lokisetsa selemo le selemo 'me (tlaase metsi) ditefello phahameng ka ho fetisisa se tlaase-tlaase phallo. Moo noka nakong metsi phahameng siea mobung lona, e matla ka ho fetisisa accumulative tshebetso. Empa alluvial mobu floodplain ke heterogeneous ka sebopeho bona. Ha moroallo o fihla, ho phalla noka ke ho itima lijo haholo haufi le bethe. Ka lebaka leo, e karolong e lebōpong la leoatle ea likaroloana tse khōloanyane li beha - lehlohlojane, lehlabathe. Ha metsi a le sieo, ka nako e thehoa mabōpo a ena le shafts. Nakoana ka ho eketsehileng ho tloha nōkeng nakong ea butle. Ho na le ba beha likaroloana o motle - yl, letsopa. Ho na le libakeng tse sa floodplain tse tlala selemo le selemo, empa feela ka likhohola tse matla. Joalo mekhahlelo mobu. Qetellong, ka terraces le ho na le reisisi, moru le mobu Meadow ba a qapa ka go tlaleletsa ka alluvium.
