Ukuhamba kwemijelo evulekileyo kufumaneka kwiNdalo nakwizakhiwo ezenziwe ngumntu. KwiNdalo, ukuhamba okuzolileyo kubonwa kwimilambo emikhulu kufutshane nemilambo yayo: umz. uMlambo iNayile phakathi kweAlexandria neCairo, uMlambo iBrisbane eBrisbane. Amanzi aqukuqelayo afumaneka kwimilambo yeentaba, imilambo engxangxasi kunye nemilambo. Imizekelo eqhelekileyo ibandakanya ii-cataracts zoMlambo iNayile, imilambo engxangxasi yaseZambesi eAfrika kunye neengxangxasi zaseRhine.
UMlambo iWisconsin kunye neentlambo zesanti ngo-Agasti, 1966 - zijonge phezulu.
Iitshaneli ezivulekileyo ezenziwe ngumntu zinokuba ziitshaneli zokubonelela ngamanzi okunkcenkceshela, umbane kunye namanzi okusela, itshaneli yokuhambisa amanzi kwizityalo zokunyanga amanzi, imijelo yamanzi emvula, imithombo ethile kawonke-wonke, ii-culverts ezingaphantsi kweendlela kunye nemigca yoololiwe.
Ukuhamba komjelo ovulekileyo kubonwa kwiimeko ezincinci kunye nezinkulu. Umzekelo, ubunzulu bokuhamba bunokuba phakathi kweesentimitha ezimbalwa kwizityalo zokunyanga amanzi kunye nangaphezulu kwe-10 m kwimilambo emikhulu. Isantya sokuhamba esiphakathi sinokuqala ngaphantsi kwe-0.01 m/s emanzini athuleyo ukuya ngaphezulu kwe-50 m/s kwindawo yokuchitheka kwamanzi ephezulu. Uluhlu lokukhupha amanzi lunokudlula ukusuka kwi-Q ~ 0.001 l/s kwizityalo zeekhemikhali ukuya kwi-Q > 10 000 m3/s kwimilambo emikhulu okanye kwiindawo zokuchitheka kwamanzi. Nangona kunjalo, kwimeko nganye yokugeleza kwamanzi, indawo yomphezulu okhululekileyo ayaziwa kwangaphambili kwaye imiselwa ngokusebenzisa imigaqo yokuqhubeka kunye nomfutho.
Ngoko ke kuphuhliso olukhawulezayo lwesayensi netekhnoloji yanamhlanje, ukuhlaziywa kwemveliso, apho iimveliso zamanzi ezilinganisa isantya sokuhamba kweendlela ezivulekileyo zikrelekrele kwaye zichanekile ngakumbi, ngolu hlobo lulandelayo:
