Imilambo, njengezinto ezibalulekileyo kwinkqubo yamanzi eMhlabeni, idlala indima ebalulekileyo ekuxhaseni iinkqubo zendalo, ekuxhaseni ubomi babantu, nasekugcineni ulungelelwano lwendalo.ukujongwa kokuhamba komlamboibalulekile kwiinjongo ezahlukeneyo, kwaye iimitha zokuhamba kwemisele evulekileyo ziye zavela njengezixhobo ezibalulekileyo kweli phulo. Uyilo lwazo olukhethekileyo kunye nokusebenza kwazo kuzenza zibe luncedo kakhulu ekuvavanyeni nasekulawuleni iinkqubo zemilambo.
Enye yeendima eziphambili zeimitha yokuhamba komjelo ovulekileyoUkujonga umlambo kukubonelela ngomlinganiselo ochanekileyo wokukhupha amanzi. Ngokungafaniyo neenkqubo zemibhobho evaliweyo, imilambo ineendawo ezinqamlezileyo ezingacwangciswanga, isantya sokuhamba kwamanzi esitshintshatshintshayo, kwaye iphantsi kwempembelelo yangaphandle efana nemvula, amaza, kunye nodaka. Iimitha zokuhamba kwemisele evulekileyo, ezidla ngokusebenzisa ubuchwepheshe obufana nee-ultrasound sensors, ii-transducers zoxinzelelo, okanye i-electromagnetic induction, zinokuziqhelanisa nezi meko ziguqukayo. Zilinganisa ubunzulu bamanzi, isantya, kunye nendawo enqamlezileyo, emva koko zibala ukukhupha okupheleleyo ngokuchanekileyo okuphezulu. Olu lwazi lubalulekile kulawulo lwemithombo yamanzi, njengoko lunceda ekumiseleni ukufumaneka kwamanzi, ukwabela izixhobo zokunkcenkceshela, ukubonelela ngamanzi okusela, kunye nokusetyenziswa kwemizi-mveliso, kwaye luvavanye impembelelo yembalela okanye izikhukula.
Iimitha zokuhamba kwamanzi ezivulekileyo nazo zidlala indima ebalulekileyo ekukhuselweni kwendalo kunye nokugcinwa kwendalo. Ngokuhlala ujonga ukuhamba komlambo, ezi zixhobo zibonelela ngengqiqo malunga nolawulo lwamanzi oluxhasa ubomi basemanzini. Iintlobo ezininzi zixhomekeke kwiimeko ezithile zokuhamba kwamanzi ukuze zizale, zifuduke, kwaye ziphile. Umzekelo, iintlanzi ezithile zifuna izinga elincinci lokuhamba kwamanzi ukuze zihambe ziye phezulu, ngelixa iindawo ezimanzi ezikufutshane nemilambo zixhomekeke kumanqanaba amanzi alinganayo ukugcina imisebenzi yazo yendalo. Idatha yeemitha zokuhamba kwamanzi inceda iiarhente zokusingqongileyo kunye nabaphandi ukuba balandele utshintsho kwiipateni zokuhamba kwamanzi, bachonge izisongelo ezinokubakho kwiinkqubo zemvelo, kwaye baphuhlise amaqhinga okulondoloza. Ukongeza, ngokujonga izinga lokuhamba kwamanzi kunye neeparameter zomgangatho wamanzi, ezi mitha zinokunceda ekufumaneni iziganeko zongcoliseko, njengokwanda ngequbuliso kwezinto ezingcolisayo ezithwalwa kukuhamba kwamanzi, okuvumela ukungenelela ngexesha elifanelekileyo.
Kwimeko yokuthintela izikhukula kunye nokunciphisa iintlekele, iimitha zokuhamba kwemisele evulekileyo azinamsebenzi. Zibonelela ngedatha yexesha langempela malunga namanqanaba omlambo kunye nesantya sokuhamba kwamanzi, nto leyo ibalulekileyo kwiinkqubo zesilumkiso kwangethuba. Ngokuhlala ubeka esweni ezi parameters, abasemagunyeni banokuqikelela ukuba umlambo ungadlula nini unxweme lwawo, bakhuphe izilumkiso zezikhukula, kwaye basebenzise izicwangciso zokufuduka ukukhusela ubomi babantu kunye nempahla. Idatha yokuhamba kwamanzi eqokelelwe zezi mitha ikwanceda ekuboniseni iingozi zezikhukula, ukuyila iziseko zolawulo lwezikhukula ezifana nee-levees kunye namadama, kunye nokuphucula ukulungela iziganeko zemozulu ezimbi kwixesha elizayo. Kwimimandla enokuchaphazeleka zizikhukula zonyaka, ulwazi oluvela kwiimitha zokuhamba kwemisele evulekileyo lubalulekile kulawulo olusebenzayo lweentlekele.
Ngaphezu koko,iimitha zokuhamba kwetshaneli evulekileyoInegalelo kuphuhliso oluzinzileyo kunye nocwangciso lweziseko zophuhliso. Kwiiprojekthi ezinje ngokwakhiwa kweebhulorho, izitishi zamandla ombane, okanye ukuzinziswa konxweme lomlambo, idatha echanekileyo yokuhamba kwamanzi ibalulekile ukuqinisekisa ukhuseleko kunye nokusebenza kakuhle kwesakhiwo. Izakhiwo zamandla ombane, umzekelo, zixhomekeke kwimilinganiselo yokuhamba kwamanzi rhoqo ukuze ziphucule ukuveliswa kwamandla kwaye ziphephe ukugqithisa izixhobo. Ngokufanayo, iinjineli eziyila iibhulorho kufuneka zazi amazinga aphezulu okuhamba kwamanzi kunye namanqanaba amanzi umlambo onokufikelela kuwo ukuqinisekisa ukuba isakhiwo sinokumelana neemeko ezinjalo. Ngokubonelela ngedatha ethembekileyo, ezi mitha zinceda ukunciphisa impembelelo yokusingqongileyo yeeprojekthi zeziseko zophuhliso kwaye ziqinisekise ukuba zakhiwe ukuze zimelane nendalo eguquguqukayo yemilambo.
Ukuqukumbela, iimitha zokuhamba kwamanzi ezivulekileyo zizixhobo ezibalulekileyo ekujongeni umlambo, zisebenza iindima ezibalulekileyo ezininzi ukusuka ekulinganiseni ngokuchanekileyo ukukhupha amanzi ukuya kukhuseleko lokusingqongileyo, ukuthintela izikhukula, kunye nophuhliso oluzinzileyo. Ukukwazi kwazo ukuziqhelanisa nobunzima beenkqubo zeendlela ezivulekileyo kunye nokubonelela ngedatha echanekileyo, yexesha langempela kuzenza zibe yimfuneko ekwenzeni izigqibo ezinolwazi kulawulo lwemithombo yamanzi. Njengoko imingeni yotshintsho lwemozulu kunye nokukhula kwemfuno yamanzi isanda, indima yeemitha zokuhamba kwamanzi ezivulekileyo ekukhuseleniiinkqubo zendalo zomlambokwaye ukuxhasa impilo-ntle yabantu kuya kuba yinto ebalulekileyo ngakumbi.
