I-Tourbidity inomthelela omkhulu emanzini echibini ngokukhuphula izinga lokushisa kanye namazinga okuhwamuka. Lolu cwaningo lunikeze ulwazi olucacile nolufingqiwe mayelana nemiphumela yokuguqulwa kwe-turbidity emanzini echibi. Inhloso eyinhloko yalolu cwaningo kwakuwukuhlola imiphumela yokuguquguquka kwe-turbidity ekushiseni kwamanzi echibini kanye nokuhwamuka. Ukuze kutholwe le miphumela, amasampuli athathwe endaweni yokugcina amanzi ngokuyihlunga ngokungahleliwe eduze kwe-reservoir course. Ukuze kuhlolwe ubudlelwano phakathi kwemfucumfucu nezinga lokushisa lamanzi kanye nokukala ukuguqulwa okuma mpo kwezinga lokushisa lamanzi, amachibi ayishumi ambiwa, futhi agcwaliswa ngamanzi anodaka. Amapani amabili ekilasi A afakwe ensimini ukuze kunqunywe umthelela we-turbidity ekuhwamukeni kwechibi. Idatha yahlaziywa kusetshenziswa isofthiwe ye-SPSS ne-MS Excel. Imiphumela ibonise ukuthi ukuguguleka kunobudlelwane obuqondile, obuqinile obuqondile nezinga lokushisa lamanzi ngo-9:00 no-13:00 kanye nobudlelwano obunamandla obungebuhle ngo-17:00, futhi izinga lokushisa lamanzi lehla liqonde phezulu ukusuka phezulu ukuya phansi. Kwaba nokushabalala okukhulu kokukhanya kwelanga emanzini amaningi anodaka. Umehluko ekushiseni kwamanzi phakathi kwezingqimba ezingaphezulu nezingaphansi bekungu-9.78°C kanye no-1.53°C emanzini amaningi axubile okungenani ngo-13:00 ihora lokubuka, ngokulandelana. I-turbidity inobudlelwano obuhle obuqondile nobuqinile nokuhwamuka kwereservoir. Imiphumela ehloliwe ibibalulekile ngokwezibalo. Ucwaningo luphethe ngokuthi ukwenyuka kokuguguleka kwechibi kukhulisa kakhulu kokubili izinga lokushisa lamanzi echibi kanye nokuhwamuka.
1. Isingeniso
Ngenxa yokuba khona kwezinhlayiya eziningi ezimisiwe, amanzi aba nemfucumfucu. Ngenxa yalokho, imisebe yokukhanya ivame ukuhlakazeka futhi imunce emanzini ngokuphambene nokuhamba kuwo ngokuqondile . Ngenxa yokuguquguquka kwesimo sezulu okungekuhle emhlabeni wonke, okuveza izindawo zomhlaba futhi kubangele ukuguguleka kwenhlabathi, kuyindaba ebalulekile emvelweni. Imithombo yamanzi, ikakhulukazi amachibi, akhiwe ngezindleko ezinkulu futhi abalulekile ekuthuthukisweni kwenhlalo-mnotho yamazwe, athintwa kakhulu lolu shintsho. Kukhona ukuhlobana okuqinile okuhle phakathi kokuvunguza nokugcwala kwenhlabathi emisiwe, futhi kukhona ukuhlobana okuqinile okungekuhle phakathi kokuqunjelwa nokungafihli kwamanzi.
Ngokwezifundo ezimbalwa, umsebenzi wokwandisa nokuqinisa indawo yokulima kanye nokwakhiwa kwengqalasizinda kukhulisa ukushintshwa kwezinga lokushisa lomoya, imisebe yelanga enetha, imvula, nokugeleza komhlaba futhi kukhulise ukuguguleka kwenhlabathi kanye nokuchithwa kwedamu. Ukucaca kanye nekhwalithi yemithombo yamanzi angaphezulu esetshenziselwa ukuhlinzeka ngamanzi, ukuchelela, kanye namandla aphehlwa ngamanzi kuthinteka yile misebenzi nemicimbi. Ngokulawula kanye nokulawula umsebenzi nezenzakalo eziwudalayo, ukwakha isakhiwo, noma ukuhlinzeka ngezinqubo ezingahlelekile ezilawula ukungena kwenhlabathi eguguleka endaweni ebamba amanzi ekhuphuka nomfula yemithombo yamanzi, kungenzeka ukwehlisa ukuguguleka kwedamu.
Ngenxa yekhono lezinhlayiya ezimisiwe lokumunca nokusakaza imisebe yelanga enetha njengoba ishaya phezu kwamanzi, ukungcola kuphakamisa izinga lokushisa lamanzi azungezile. Amandla elanga izinhlayiya ezimisiwe eziwamunce akhishwa emanzini futhi akhulise izinga lokushisa lamanzi eduze nendawo. Ngokunciphisa ukugcwala kwezinhlayiya ezimisiwe futhi kuqedwe i-plankton ebangela ukuthuthumela kwande, izinga lokushisa lamanzi axubile lingancipha. Ngokwezifundo ezimbalwa, ukuvuthuluka nezinga lokushisa kwamanzi kokubili kuncipha eduze kwe-axis yobude bendawo yokugcina amanzi. I-turbidimeter iyithuluzi elisetshenziswa kakhulu ukukala ukuxubeka kwamanzi okubangelwa ukugcwala kwenhlabathi emisiwe.
Kunezindlela ezintathu ezaziwayo zokumodela izinga lokushisa kwamanzi. Womathathu lawa mamodeli anezibalo, e-deterministic, kanye ne-stochastic futhi anezingqinamba zawo namasethi edatha okuhlaziya izinga lokushisa lemithombo yamanzi ehlukahlukene. Kuye ngokutholakala kwedatha, womabili amamodeli ezibalo zepharamethikhi kanye ne-nonparametric asetshenziselwe lolu cwaningo.
Ngenxa yendawo yawo engaphezulu, amanzi amaningi ahwamuka emachibini okwenziwa nasemachibini kunakweminye imithombo yamanzi yemvelo. Lokhu kwenzeka lapho kunama-molecule amaningi anyakazayo ahlukana namanzi futhi abaleke aye emoyeni njengomhwamuko kunama-molecule angena kabusha emanzini esuka emoyeni bese evaleleka oketshezini.
