Masijonge kwiindlela ezahlukeneyo zokusetyenziswa kweemitha zokuhamba kwemizi-mveliso ezivulekileyo kwaye siqonde ukubaluleka kwazo kwiindawo ezahlukeneyo.

• Ulawulo lwemithombo yamanzi:
  Enye yeendlela eziphambili zokusebenzisa iimitha zokuhamba kwamanzi ezivulekileyo kukulawula amanzi. Ezi mitha zisetyenziselwa ukulinganisa ukuhamba kwamanzi emilanjeni, kwimijelo nakwimijelo yamanzi, zibonelela ngedatha ebalulekileyo yokucwangcisa imithombo yamanzi, ulawulo lwezikhukula kunye nokubeka esweni okusingqongileyo. Ngokulinganisa ngokuchanekileyo ukuhamba kwamanzi, abasemagunyeni banokwenza izigqibo ezinolwazi malunga nokusasazwa kwamanzi, ukunkcenkceshela kunye nokuveliswa kwamandla ombane ngamanzi.
• Unyango lwamanzi amdaka:
  Kwihlabathi lokunyanga amanzi amdaka, iimitha zokuhamba kwamanzi amdaka zibalulekile ekujongeni ukuhamba kwamanzi amdaka kwiindlela ezivulekileyo kunye nemijelo yamanzi amdaka. Ngokulinganisa ngokuchanekileyo ukuhamba kwamanzi, ezi zixhobo zinceda ukuphucula iinkqubo zonyango, ukuqinisekisa ukuthotyelwa kwemigaqo yokusingqongileyo kunye nokuvavanya ukusebenza kakuhle kwezityalo zonyango. Ukongeza, zidlala indima ebalulekileyo ekufumaneni naziphi na izinto ezingaqhelekanga okanye izithintelo ekuhambeni kwamanzi amdaka, zenza ulondolozo ngexesha elifanelekileyo kunye nokuthintela iingxaki ezinokubakho.
• Isicelo semizi-mveliso:
  Iimitha zokuhamba kwemisele evulekileyo zisetyenziswa kakhulu kwiinkqubo ezahlukeneyo zoshishino ezibandakanya ukuthuthwa kolwelo kwiimisele ezivulekileyo. Amashishini afana neekhemikhali, iikhemikhali zepetroli, ukutya neziselo axhomekeke kwezi zixhobo ukulinganisa ukuhamba kwezinto eziluhlaza, ukucubungula amanzi kunye namanzi amdaka. Ngokubeka esweni ukuhamba kwamanzi, amashishini angenza ngcono iinkqubo zawo zemveliso, aqinisekise ukusetyenziswa kakuhle kwezixhobo, kwaye athobele imigangatho yolawulo enxulumene nokukhutshwa komoya kunye nempembelelo yokusingqongileyo.
• Ezolimo kunye noNcedo:
  Ngeenjongo zolimo, iimitha zokuhamba kwamanzi ezivulekileyo zisetyenziselwa ukulinganisa ukuhamba kwamanzi kwimisele yokunkcenkceshela kunye nemijelo. Abalimi kunye nabasemagunyeni bokunkcenkceshela basebenzisa le datha ukulawula ukwabiwa kwamanzi, ukuphucula iishedyuli zokunkcenkceshela kunye nokuqinisekisa ukusetyenziswa kwamanzi ngokuchanekileyo ekulimeni izityalo. Ngokulinganisa ngokuchanekileyo ukuhamba kwamanzi, iimitha zokuhamba kwamanzi ezivulekileyo zinegalelo kwizenzo zolimo ezizinzileyo kunye nemizamo yokulondolozwa kwamanzi.
• Uphando lwe-hydrological:
  Iimitha zokuhamba komlambo ezivulekileyo zidlala indima ebalulekileyo kuphando lwe-hydrological, apho ukulinganisa ukuhamba komlambo kunye nokuhamba komlambo kubalulekile ekuqondeni intshukumo yomzimba wamanzi. Abaphandi kunye neengcali zendalo basebenzisa ezi mitha ukuqokelela idatha yokufunda indlela ezisebenza ngayo umlambo, ukuthuthwa kwedaka kunye nentshukumo yendalo. Ulwazi olufunyenwe kwiimitha zokuhamba komlambo ezivulekileyo lunceda ekuphuhliseni iimodeli zokuqikelela izikhukhula, ulawulo lwamanzi, kunye nokukhuselwa kwendalo.

Ukuqukumbela, ii-flowmeters ze-open channel zineendlela ezahlukeneyo zokusetyenziswa kwiinkalo ezahlukeneyo, ukusuka kulawulo lwemithombo yamanzi kunye nonyango lwamanzi amdaka ukuya kwiinkqubo zoshishino, ezolimo kunye nophando. Ukukwazi kwazo ukulinganisa ngokuchanekileyo ukuhamba kolwelo kwii-open channels kuzenza zibe sisixhobo esibalulekileyo sokujonga, ukulawula kunye nokwenza izigqibo. Njengoko ubuchwepheshe buqhubeka buhambela phambili, ii-open channel flow meters kulindeleke ukuba zidlale indima ebaluleke ngakumbi ekuqinisekiseni ulawulo olufanelekileyo noluzinzileyo lwemithombo yamanzi kunye neenkqubo zoshishino.
