Ngokusheshisa ukukhula kwamadolobha ezweni lakithi, izinhlekelele ezinkulu zokugcwala kwamanzi zenzekile kwezinye izindawo.NgoJulayi 2021, iSifundazwe sase-Henan sabhekana nezimvula ezinkulu kakhulu, ezadala ukugcwala kwamanzi edolobheni nasezitimeleni ezihamba ngaphansi komhlaba, okwaholela ekulahlekelweni okukhulu kwezomnotho kanye nokufa kwabantu. kanye nezimoto ezikhubazekile, okwathinta kakhulu ukuphila kwezakhamuzi zendawo.Lezi zinkinga zokugcwala kwamanzi ziwumphumela wokwanda okuqhubekayo kokwakhiwa kwedolobha, ukwanda okuqhubekayo kwendawo yokwakha, nokuncipha kwendawo eluhlaza.Ziphinde zibe yinkomba yokunganele komthamo wokudonsa amanzi ohlelo lokudonsa amanzi emadolobheni.
Eminyakeni yamuva nje, ukwakhiwa kwedolobha lesipontshi sekungomunye wemisebenzi ebalulekile yokwakhiwa kwedolobha noguquko.
Ezidingweni zokwakhiwa kwamadolobha espontshi, kuthiwa kumele kuhlanganiswe okumpunga nokuluhlaza, kuhlanganiswe nezinsiza zokuthuthukisa ezinganawo umthelela omncane kanye nezinhlelo zikamasipala zokudonsa amanzi, kuphinde kusetshenziswe izindawo zokuthuthukisa amanzi emvula ukuze kuphinde kusetshenziswe amanzi emvula uma imvula incane, amanzi emvula. emgwaqeni kuyaqoqwa futhi kukhishwe amanzi ngesikhathi ngohlelo lokudonsa amanzi kamasipala uma imvula ine kakhulu.Inkinga yokugcwala kwamanzi emadolobheni ayibonakali nje kuphela endaweni eluhlaza elinganiselwe yedolobha, kodwa futhi nokunganele komthamo wokugeleza kwamanzi wesistimu yokudonsa amanzi kamasipala wedolobha uqobo.
Njengengxenye ebalulekile yohlelo lokudonsa amanzi emadolobheni, imigudu yokudonsa amanzi idlala indima yokuqoqa amanzi emvula.Umthambeka nezinto ezisetshenziswayo ezamukelwa ekwakhiweni kwemigudu yokudonsa amanzi zingadlala indima ephambukisayo, zisheshise ukugeleza kwamanzi emvula, futhi zinciphise ngempumelelo ukwenzeka kokuchitheka kwamanzi emadolobheni. Imigudu yokukhipha amanzi ingahlukaniswa ibe imisele yamaphuzu kanye nemisele yemisele ewumugqa ngokuvumelana nesakhiwo sayo. .Imisele yamaphuzu ayimisele yamanzi emvula emiswe ngezikhathi ezithile emigwaqweni nasemigwaqweni ukuze iqoqe futhi ikhiphe amanzi emvula.Imisele ewumugqa yizindawo zokuphuma kwamanzi emvula eziqhubekayo ezihlelwe eduze kwemigwaqo nasemaceleni, axhuma zonke izindawo zokuphuma amanzi emvula zibe ulayini.Banomsebenzi wokuqoqa ngokushesha amanzi emhlabathini, okuvumela amanzi emvula angaphansi komhlaba ukuthi asabalaliswe ngokunengqondo kunethiwekhi yamapayipi okudonsa amanzi asemadolobheni futhi aphume.
Esikhathini esidlule ukuhlelwa kwedolobha kanye nomklamo, ngenxa yokucatshangelwa kwezindleko, izindawo eziningi zasemadolobheni zazisebenzisa imisele yamanzi. ejwayele ukuba nenkinga yokuvinjwa kwepayipi lokudonsa amanzi, okuholela ekunqwabeleni kwamanzi amaningi kuleyo ndawo yokukhipha amanzi.Ukwengeza, ngesikhathi semvula enamandla eqhubekayo, kulula ukubangela ukunqwabelana kwamanzi emgwaqeni ngenxa yomthamo onganele wokukhipha amanzi, okuthinta ukuhamba kwabantu kwansuku zonke.
Ngakho-ke, ngokuthuthukiswa kwamadolobha, uhlelo lokuqala lokudonsa amanzi lwedolobha ludinga ukuguqulwa, futhi imisele yamaphuzu enamandla okudonsa amanzi ithathelwe indawo imisele yamanzi ewumugqa enomthwalo ophakeme wokudonsa amanzi. zenzelwe ukuhlela ngokuqhubekayo izindawo zokudonsa amanzi zibe ulayini.Ukuzinza kokugeleza komsele womzila womugqa kuthuthukiswa kakhulu, ukuze kungabikho indawo enkulu yokunqwabelana kwamanzi endaweni yokukhipha amanzi ngenxa yokuvaleka kwendawo ethile yokukhipha amanzi. ngesikhathi esifanayo, amadreyini aqondile angafakwa ezindaweni eziningi.Ngaphezu kokufaneleka emigwaqweni kamasipala nemigwaqo, ingasetshenziswa nasezikhumulweni zezindiza, emapaki ezimboni nakwezinye izindawo.Amapayipi emisele alayini angamasistimu ahlanganisiwe ahlanganiswe izingxenye ezihlukahlukene.Inhlanganisela yemojula yokucaciswa okuhlukahlukene ingahlangabezana nezidingo ezahlukahlukene zamakhasimende.Umqondo wawo wokuklama oyingqayizivele udala indawo eyengeziwe yokucabangela abaklami.Kungumkhiqizo onokwethenjelwa futhi onokwethenjelwa emkhakheni wezakhiwo zesimanje futhi enye yezingxenye ezibalulekile zesistimu yesimanje yokudonsa amanzi emadolobheni.
