Umthelela kagesi ophehlwa ngamanzi kukhwalithi yamanzi unezici eziningi. Ukwakhiwa nokusebenza kwezikhungo zokuphehla ugesi ngamanzi kuzoba nemithelela emihle nemibi eqophelweni lamanzi. Imithelela emihle ihlanganisa ukulawula ukugeleza kwemifula, ukwenza ngcono izinga lamanzi, nokukhuthaza ukusetshenziswa okunengqondo kwemithombo yamanzi; Imithelela engemihle ihlanganisa ukunwetshwa kwezindawo zamanzi echibini kanye nokuncipha kwamandla okuzihlanza emizimbeni yamanzi.
Umthelela omuhle wokuphehlwa ngamanzi kwikhwalithi yamanzi
Amandla kagesi anezinzuzo eziyingqayizivele ekuvikelweni kwemvelo. Uma kuqhathaniswa nokukhiqizwa kwamandla kagesi wezinsalela zakudala, ugesi ophehlwa ngamanzi awukhiphi amagesi ayingozi nezinhlayiyana, futhi awungcolisi indawo ezungezile. Ngesikhathi esifanayo, ukwakhiwa nokusebenza kweziteshi eziphehla ugesi ngamanzi kunomthelela omncane uma kuqhathaniswa nemithombo yamanzi futhi ngeke kudale umonakalo ohlelweni lwendalo lwasemanzini. Ngaphezu kwalokho, ugesi ophehlwa ngamanzi ungalawula kahle ukugeleza kwemifula, uthuthukise izinga lamanzi, futhi ukhuthaze ukusetshenziswa okunengqondo kwemithombo yamanzi.
Umthelela omubi wokuphehla kwamandla emanzini kwikhwalithi yamanzi
Nakuba amandla aphehlwa ngamanzi anezinzuzo ekuvikelweni kwemvelo, ukwakhiwa nokusebenza kwawo kungase kube nomthelela omubi eqophelweni lamanzi. Ukwakha amadamu ukuze kuvinjwe futhi kugcinwe amanzi kungabangela amanzi agelezayo abe amanzi amile, kunciphise umthamo wokuzihlanza emzimbeni wamanzi. Ukukhula ngokweqile kolwelwe kungaholela eutrophication yamanzi echibini kanye nokwehla kwezinga lamanzi. Ukwengeza, ukwakhiwa kwamadamu kungase kwenyuse amathuba ezikhukhula, kuvimbe noma kuguqule imifudlana, kulimaze imvelo yasekuqaleni engaphansi kwamanzi, kwehlise izinga lokusinda kwezinye izinhlobo zezilwane ezingaphansi kwamanzi, futhi kuholele ekuqothulweni kwezinhlobo zezilwane.
Ungawunciphisa kanjani umthelela ongemuhle kagesi ophehlwa ngamanzi kwikhwalithi yamanzi
Ukunciphisa umthelela ongemuhle kagesi ophehlwa ngamanzi kwikhwalithi yamanzi, ezinye izinyathelo zingathathwa. Isibonelo, ukuphambukisa ingxenye yomthombo wamanzi edamini uyiswe endaweni ekhethiwe ukuze kuqinisekiswe ubuqotho bemvelo, ukulawula ukuziphatha kokungcoliswa kwamafekthri agudle umfula kanye nemikhuba emibi yezakhamuzi. Ukwengeza, izindlela zokuhlela nezokwakha eziphusile ngokwesayensi nazo zibalulekile ekwehliseni imithelela emibi.
