Ukukhukhuleka kunomthelela omkhulu emanzini echibi ngokunyusa amazinga okushisa nokuhwamuka. Lolu cwaningo lunikeze ulwazi olucacile nolufushane mayelana nemiphumela yokuguqulwa kokukhukhuleka emanzini echibi. Inhloso eyinhloko yalolu cwaningo kwakuwukuhlola imiphumela yokushintsha kokukhukhuleka ekushiseni kwamanzi echibi kanye nokuhwamuka. Ukuze kutholakale le miphumela, amasampula athathwe echibi ngokulihlukanisa ngokungahleliwe endleleni yechibi. Ukuze kuhlolwe ubudlelwano phakathi kokukhukhuleka kanye nokushisa kwamanzi kanye nokukala ukushintsha okuqondile kokushisa kwamanzi, amachibi ayishumi ambozwe, futhi agcwaliswa ngamanzi akhukhulekile. Amapani amabili ekilasi A afakwe ensimini ukuze kutholakale umthelela wokukhukhuleka ekuhwamukeni kwechibi. Idatha yahlaziywa kusetshenziswa isofthiwe ye-SPSS kanye ne-MS Excel. Imiphumela ibonise ukuthi ukukhukhuleka kunobudlelwano obuqondile, obuqinile nokushisa kwamanzi ngo-9:00 no-13:00 kanye nobudlelwano obunamandla obubi ngo-17:00, futhi izinga lokushisa lamanzi lehla ngokuqondile kusukela phezulu kuya kwengqimba engezansi. Kwakukhona ukuphela okukhulu kokukhanya kwelanga emanzini amaningi akhukhulekile. Umehluko ekushiseni kwamanzi phakathi kwezingqimba eziphezulu nezingezansi wawungu-9.78°C kanye no-1.53°C emanzini amaningi kanye namanzi angangcolisi kakhulu ngo-13:00 ihora lokubuka, ngokulandelana. Ukungcolisa kunobuhlobo obuqondile nobuqinile nokuhwamuka kwamanzi echibini. Imiphumela evivinyiwe yayibalulekile ngokwezibalo. Ucwaningo luphethe ngokuthi ukwanda kokungcolisa kwamanzi echibini kukhulisa kakhulu izinga lokushisa kwamanzi echibini kanye nokuhwamuka kwamanzi.
1. Isingeniso
Ngenxa yokuba khona kwezinhlayiya eziningi ezilengayo, amanzi aba yimfucumfucu. Ngenxa yalokho, imisebe yokukhanya inamathuba amaningi okusabalala nokumuncwa emanzini kunokuba ihambe kuwo ngqo. Ngenxa yokushintsha kwesimo sezulu okungekuhle emhlabeni wonke, okuveza ubuso bomhlaba futhi kubangele ukuguguleka kwenhlabathi, kuyinkinga enkulu emvelweni. Imizimba yamanzi, ikakhulukazi amadamu okugcina amanzi, akhiwe ngezindleko ezinkulu futhi abalulekile ekuthuthukisweni kwezomnotho kwezenhlalo nakwezomnotho kwamazwe, athintwa kakhulu yilolu shintsho. Kukhona ubudlelwano obuhle obuqinile phakathi kokuguguleka kanye nokugcwala kwenhlabathi okulengayo, futhi kukhona ubudlelwano obuqinile obubi phakathi kokuguguleka kanye nokubonakala kwamanzi.
Ngokusho kwezifundo eziningana, umsebenzi wokwandisa nokuqinisa amasimu kanye nokwakhiwa kwengqalasizinda ukhulisa ushintsho lokushisa komoya, imisebe yelanga, imvula, kanye nokugeleza komhlaba futhi ukhulisa ukuguguleka kwenhlabathi kanye nokuchitheka kwenhlabathi. Ukucaca kanye nekhwalithi yezindawo zamanzi ezingaphezulu ezisetshenziselwa ukuhlinzeka ngamanzi, ukunisela, kanye namandla kagesi kuthinteka yile misebenzi kanye nemicimbi. Ngokulawula nokulawula umsebenzi kanye nemicimbi ebangela lokho, ukwakha isakhiwo, noma ukuhlinzeka ngezindlela ezingezona izakhiwo ezilawula ukungena kwenhlabathi egugulekile endaweni engenhla yamanzi ezindawo zamanzi, kungenzeka ukunciphisa ukungcoliswa kwezindawo zamanzi.
Ngenxa yokuthi izinhlayiya ezilengayo ziyakwazi ukumunca nokusabalalisa imisebe yelanga njengoba ishaya ebusweni bamanzi, ukuguguleka kuphakamisa izinga lokushisa lamanzi azungezile. Amandla elanga adonswe yizinhlayiya ezilengayo akhishwa emanzini futhi andise izinga lokushisa lamanzi eduze kobuso. Ngokunciphisa ukugcwala kwezinhlayiya ezilengayo nokususa i-plankton ebangela ukuguguleka kwamanzi, izinga lokushisa lamanzi alengayo lingancishiswa. Ngokusho kwezifundo eziningana, ukuguguleka kwamanzi kanye nokushisa kwamanzi kokubili kwehla eceleni kwe-axis ende yendlela yamanzi echibini. I-turbidimeter iyithuluzi elisetshenziswa kakhulu ekulinganiseni ukuguguleka kwamanzi okubangelwa ukuba khona okuningi kokugcwala kwenhlabathi elengayo.
Kunezindlela ezintathu ezaziwayo zokulinganisa izinga lokushisa lamanzi. Zonke lezi zinhlobo ezintathu ziyizibalo, zinqunyelwe, futhi zisezingeni eliphansi futhi zinemingcele yazo kanye namasethi edatha okuhlaziya izinga lokushisa lezindawo ezahlukahlukene zamanzi. Kuye ngokutholakala kwedatha, zombili izinhlobo zezibalo ze-parametric kanye ne-nonparametric zasetshenziswa kulolu cwaningo.
Ngenxa yendawo yabo enkulu ebusweni, inani elikhulu lamanzi liyahwamuka emachibini nasezindaweni zokugcina amanzi ezenziwe ngokwenziwa kunakweminye imithombo yamanzi yemvelo. Lokhu kwenzeka lapho kunezinhlayiya eziningi ezihambayo eziphuma ebusweni bamanzi bese zibaleka ziye emoyeni njengomhwamuko kunama-molecule aphinde angene ebusweni bamanzi emoyeni bese ebhajwa oketshezini.
