Kuyini umfula, iziphi emfuleni

ukuphila komuntu njalo ubulokhu uhlangene eduze exhunywe kwi emifuleni. Kwakungekhona kuphela esikhathini esidlule, kukhona ukuhlobana ezinjalo namuhla. nemizana wokuqala wabo abantu njalo eyakhelwe kwaleli chibi, eduze imithombo yamanzi ahlanzekile. Zazisetshenziswa ukudoba kanye neensetjenziswa, njengoba wokuxhumana, kwathiwa wahamba phezu ihlathi. Namuhla, bonke emadolobheni amakhulu emhlabeni zitholakala emifuleni emikhulu futhi amagama abo izwakala omqondofana: London futhi iThames, the Seine kanye Paris, Petersburg uMfula iNeva, New York kanye Hudson.

Ngisho esikoleni, sonke siyazi ukuthi lo mfula, kanye lokuthi ukugeleza kwamanzi kuyinto sekhefu, okuthiwa i-track. Ngamunye wabo, efana nakho konke okunye kuleli zwe lenesicalo, ibizwa ngokuthi umthombo. A confluence olwandle, ulwandle noma echibini ibizwa ngokuthi umlomo.

Amanzi ukugeleza Ungase futhi abazitika nezinye, usayizi omkhudlwana. Isiteshi esiyinhloko nazo zonke nemingenela yayo yakha uhlelo emfuleni.

Njalo umfula, kungakhathalekile ubungako bawo, unendlela yawo yokubhukuda - endaweni ethile, okuyinto eliluqoqayo ngaphezulu nangaphansi komhlaba. Umngcele esasihlukanisa amachibi ibizwa ngokuthi nakangaka.

Yengane futhi amandla

Ukukhuluma ngalokho umfula kufanele nakanjani ukusho ukusebenza kwawo. Ukudla ukuvundulula amanzi enhlabathini, izinga kanye ukugeleza senzeka unyaka wonke kuyinto engalingani. Ngenxa yalokho izinguquko ezithile zonyaka ka ezingeni amanzi kwabantu bemikhakha ehlukene kanye nezinye izinkomba.

Imodi ngokuvamile izingxenye izinkathi eziningana. Kuyini kwesikhukhula, sabona konke - ukuchitha yansukuzonke yonyaka kwelinye futhi ngesikhathi esifanayo ngeke zinganakwa. Izinga lamanzi linyuka emgqeni ukuze udla izindwani. Ngokulinganayo eshiwo ngokucacile futhi inkathi ehlukile - amafishane. Ngalesi sikhathi, izinga lamanzi kuyinto ephansi, okuyinto kubangelwa zokunciphisa izimali zayo kusukela endaweni okulawulwa kwemithombo yamanzi. Futhi ke kukhona izikhukhula - kusenjalo ezingeni kuyanda kubangelwa nezimvula ezinkulu noma ngokushesha iqhwa ukuncibilika kakhulu.

Lokho abayikho

Kuye izinhlobo zosizo, ngesikhathi lapho zenzeka, amanzi notshwala zihlukaniswe amaqembu amabili:

• plain;
• entabeni.

Ukuze phezu flat lomfula uyephuza, ngoba imisuka zabo engamamitha ongaphakeme kanye emthambekeni sezwe phezu lapho flow, amancane. Valley zingabantu ububanzi, ne emithambekeni emnene. Esinye sezibonelo zalokhu emifuleni China elikhulu: umfula iYangtze kanye Yellow River. Lezi zaziwa kithi njengoba iVolga, Dnieper, Don nabanye.

Ezintabeni, okusheshayo kakhulu, kusukela imithombo zitholakala okusezingeni eliphezulu kanye umlomo - emathafeni. Emthambekeni indawo kakhulu, kuhambisana emanzini ahamba ngesivinini, "slotting" kwamadwala nzima amakhulu ezinkulungwane eminyakeni lezigodi emincane emithambekeni emaweni. Kuyini umfula ogeleza ezintabeni? Kuyinto namandla, sesifufula engenakunqandeka sukela ngoba tumbleweed kanye Rapids. Mhlawumbe omele ovelele kuleli qembu yilona Yenisei.

Ingxenye ukugeleza, oqala ngo ezintabeni, kokushiya indiza, ushintshe uhlamvu yabo ekubeni emathafeni entabeni. Izibonelo ezinye imifula Bashkiria, umsuka zazo zitholakala emithambekeni esentshonalanga yezintaba zase-Ural. I mfula main weRiphabhulikhi - k. White, ogwini olunothile zazo zitholakala emadolobheni amancane namakhulu. Kwehla ezintabeni, le liphindele emathafeni Ural baqoqe amanzi nenqwaba nemingenela eminingi, kuba amandla nokuthunyelwa.
