Lokhu kuphakamisa ukuthi imvamisa namandla azo zombili isomiso nezikhukhula zizoqhubeka zikhuphuka ngokuhambisana nezinga lokushisa elijwayelekile, ngakho-ke kubeka amakhulu ezigidi zabantu engcupheni yokuntuleka kwamanzi ahlanzekile. Amadolobha afana neKapa asevele ezwa amandla aphelele ale miphumela.
Unyaka wezi-2018 bekufanele kube wusuku iKapa elacisha ngalo ompompi balo, uSuku lweZero lokuqala emhlabeni. Izakhamuzi bezibhekene nethuba lokuma ulayini amahora amaningi kompompi ukuze zithole ukudla okulinganiselwe kwansuku zonke okungamalitha angama-25 ngosuku, njengoba umphakathi wawungeke uvunyelwe ukuthola amanzi ngenxa yesomiso esibi kakhulu. Amanye amadolobha amakhulu amadolobha amaningi ayaziwa ukuthi asondela ku-zero emashumini eminyaka ezayo
Kodwa-ke, ososayensi nabacwaningi basebenzela izindlela ezehlukene zokukhiqiza amanzi ahlanzekile ukusuka ezinhlelweni ezincane ukuya ezinhlelweni zezohwebo nezimboni. Izindlela ezisetshenziswa kakhulu zokususa usawoti emanzini manje, yizikhungo zokususa usawoti emanzini ashisayo kanye nezinhlelo zolwelwesi. Isistimu eshisayo isebenzisa ukushisa. Nakuba amasistimu obhayela emba eqolo futhi edinga imithombo yamandla emba eqolo, le ndlela iwushintshe kakhulu umhlaba ekukhiqizweni kwamanzi ahlanzekile. Ngakolunye uhlangothi, amasistimu e-Membrane awadingi izindlela eziningi eziyinkimbinkimbi. Ngokusebenzisa ukucindezela kanye nohlobo olukhethekile lolwelwesi oluneshidi elivuzayo elivumela kuphela amanzi ahlanzekile ukuba adlule kulo. Ngale ndlela, amanzi ahlanzekile akhiqizwa ngokushesha okukhulu.
Amadolobha emhlabeni wonke anenkinga yokungavikeleki kwamanzi. Ukushintsha kwesimo sezulu kubangela ukwanda kwamazinga okushisa amaphakathi kanye nezinkathi eziqhubekayo zesomiso sezulu. Isidingo ngaphansi kwalezi zimo siyenyuka, kodwa imvula ebambezelekile noma engekho ngesikhathi sonyaka inciphisa ukutholakala, ngakho-ke ibeka ubunzima obukhulu ezinsizeni. Lokhu kushoda kwamanzi ahlanzekile emadolobheni kuyibeka engcupheni yokufinyelela ku-Day Zero yayo. I-Day Zero ngokuyisisekelo isikhathi esilinganiselwe lapho idolobhakazi noma isifunda singakwazi ukuhlinzeka indawo yaso ngamanzi ahlanzekile. Umjikelezo we-hydrologic uxhunyaniswe eduze nezinguquko kuzinga lokushisa lomoya kanye nebhalansi yemisebe, okusho ukuthi isimo sezulu esifudumele siholela emazingeni aphezulu okuhwamuka kanye nokwenyuka kwemvula yoketshezi.
NgoHID , siyaziqhenya ngokuba enye yezinkampani ezihamba phambili ezisebenzela ukulwa ne-Day Zero mark ezifundeni eziningi emhlabeni okungenzeka zibe sengozini yokushoda kwamanzi. Ithimba lethu labacwaningi lisebenzela ukukhiqiza ulwelwesi lwekhwalithi ephezulu oludinga amandla amancane ukuze luvune amanzi okuphuza ahlanzekile. Sikhuthaza umhlaba ukuthi ulondoloze kakhulu insiza eyigugu futhi sibambane ngezandla futhi silwe ne-Day Zero emhlabeni wonke.
