Uyini owumthelela emfuleni? Ukucacisa incazelo, izici

Owumthelela - yamanzi, emlonyeni esimelela elikhulu wamanzi abalulekile, ichibi noma ezinye emanzini amaningi. Ngo geography kukhona into enjalo njengoba isiteshi esikhulu. Kuyinto kuye futhi baphathe ziyamaniswa nokungangeni yabo amanzi. Asithathe sihlolisise kwencazelo, ubheke izindlela ngezigaba kanye izici zalesi ingxenye emfuleni.

Enye owumthelela libizwa izindleko amanzi, ngokuletha wamanzi besezwa echibini, Echibini noma ezinye ndawo.

I inflow lomfula: incazelo emfushane

Ngakho, kusukela phezulu kusobala ukuthi ukugeleza ngaphezu komfula main. It ihlukile ukusakaza main aqueous ngokuyinhloko yamanzi. Ukufika lesi sibalo ephansi kakhulu kunalelo emfuleni kulo kugeleza. Kukhona nezinye izindawo umehluko zindlela. Lona izinga lokushisa lamanzi, nombala inkomba, turbidity (ukucaciseleka) kanye nokusungulwa zamakhemikhali. Ngokuphathelene nesimo ukugeleza kwamanzi, kungase futhi ziyahlukahluka. Ngokwesibonelo, ukuthutheleka - komhosha, futhi isiteshi esikhulu odabula ithafa, nge ukugeleza engaguquki. Kule kuphakama esiphethweni esisodwa: isakhiwo ogwini kungenzeka ngokuphongoza. Futhi-ke, ubude. Lesi sibalo isezingeni ukugeleza kwamanzi main uhlale mkhulu ngoba nemingenela.

Kumele kukhunjulwe ukuthi umfula ngayo yonke nemingenela yayo ibizwa ngokuthi uhlelo emfuleni. Isibalo kwemali ku yamanzi kungaba okuhluke ngokuphelele. Ngezinye izikhathi kunzima ukunquma lapho umfula oyinhloko nemingenela yayo lapho. Kwenzeka ukuthi ubukhulu yokugcina kungenzeka kakhulu kunangendlela isiteshi esikhulu.

Lapho ekuqaleni ukuthutheleka

Umsuka walo inflow umfula uthatha emithonjeni, emaxhaphozini, izintaba, izinguzunga zeqhwa. umthombo wayo ubhekwa indawo lapho ithrekhi ukhonkolo iqala ukugeleza esitebeleni. Owumthelela - umfula lapho ukhiphela ukusakaza njalo yamanzi engokwemvelo. Ngulona logeleta kanye isiteshi side kusukela ekuqaleni umthombo emlonyeni. Ukuze nemingenela ukunquma emthambekeni eyisihlobo sezwe, njengoba umthetho, kuba ngokuphelele phansi.

ngezigaba nemingenela

Ingxenye uhlelo ingeminye ukuthutheleka. Kubandakanya kukhona nomfula omkhulu, futhi fudlana. Kukhona into efana kwesokudla nemingenela kwesokunxele. Kusukela igama kuba sobala ukuthi ukugeleza kuqala bomthombo ka ohlangothini lwesokudla e ukugeleza isiqondiso, kanti owesibili, ngokulandelana, kusuka kwesobunxele.

Egatsheni eyinhloko emfuleni wabukela oda 1st. Lawa ukusakaza ukuthi ageleze ngqo kuwo. Nokho bebizwa - the nemingenela eyinhloko emfuleni. Ngakho ageleza 2nd oda ukugeleza phakathi nemingenela ye-oda 1st, nokunye. D. Ngenxa yalesi ngezigaba ukuze uhlelo emfuleni futhi emifuleni emikhulu nemifudlana emincane.

On iplanethi enguMhlaba, kukhona ukusakaza ukuthi kukhona nemingenela labangaba ngu-20 ama-oda ezidlula. Futhi, kukhona enye ngezigaba: kusukela komncane kuya ezinkulu.

izici nemingenela

inflow ngasinye, kanye emfuleni esikhulu, inezici ayo kanye nezici:

• usayizi ngasemseleni wamanzi;
• abakule ndawo okuthathwe kuyo;
• amanzi emifula yonyaka;
• kwabantu inethiwekhi emfuleni;
• iwe futhi emthambekeni emfuleni.

Kumephu Ukraine, isibonelo, kukhona angaba yizinkulungwane 71. Rivers. Imithombo main wamanzi imali izifunda eziningi ukuhlala wamanzi esemqoka kanye inflow omfula kugeleza endaweni ethile, okuyiwona, futhi yenza ezibalulekile. Ukusakaza enjalo ekubeni yingxenye ebalulekile eyisisekelo ohlelweni imvelo, umthombo wamanzi ukuphuza amanzi ezimbonini.
