Ngokwesimo sokuwa kwebhange, ngenxa yomehluko wesimo sokwakheka kwechibi logu lolwandle kulo lonke usebe lomkhakha, izinhlobo ezahlukene, izikali nezindlela zokuwa kwebhange zenzeka. Ngakho-ke, iphrojekthi yokulawula ukuwa kwebhange kufanele iqondiswe kakhulu futhi akufanele yenziwe ngobumpumputhe noma isebenzise ngokungaboni izinyathelo ezithile zokuvimbela nokulawula ubunjiniyela. Kufanele iphathwe ngamakhambi kanye nokuphathwa okuphelele.

Ukuthatha izinga lamanzi aphansi eliklanyelwe njengomngcele, ingxenye engaphezulu iphrojekthi yokuvikela umthambeka futhi ingxenye engezansi iphrojekthi yokuvikela unyawo. Iphrojekthi yokuvikela ukuthambekela iwukulungisa umthambeka wokuqala wasebhange bese wendlala ungqimba lwesihlungi sokuvikela ukuthambekela kanye nongqimba olungaphezulu lwesakhiwo segridi ye-ecological mat ukuvimbela ukukhucululwa kwamanzi, umthelela wamagagasi, ukuguquka kwezinga lamanzi kanye nokuguguleka kwamanzi angaphansi komhlaba ukuthi angalimazi indawo eyehlelayo yasebhange; iphrojekthi yokuvikela unyawo isebenzisa izinto zokulwa nokukhuhla ukuze ibeke umfula ongaphansi kwamanzi eduze nonyawo lomthambeko ukuze wenze isendlalelo sokuvikela ukuvimbela ukukhucululwa kwamanzi nokufeza inhloso yokuvikela isisekelo se-embankment. Inzuzo enkulu ye-gabion mesh imvelo yayo. Igcwele amatshe emvelo. Kukhona izikhala phakathi kwamatshe, okuvumela izitshalo ukuba zikhule kuwo. Izitshalo ezifanele zingahlwanyelwa ngendlela ehlosiwe. Inemisebenzi emibili yokuvikela ukuthambeka kobunjiniyela kanye nokuvikela ukuthambeka kwezitshalo.
Uhlelo lokwakha uhlaza kufanele lwenziwe ngokohlobo lwenhlabathi yendawo, ukujiya kongqimba lwenhlabathi, uhlobo lwesigaba esiphambanayo, ukuzinza okuphelele, ukuthambekela, izici zokukhanya, ukuphakama, izimo zezulu kanye nezidingo zendawo, njll., futhi inqubo yokwakhiwa kwe-mesh mat nebhokisi lemeshi kufanele ilungiswe ngokufanele ngokufanele.
Uhlobo lwezitshalo olufanele kufanele lukhethwe ngokuya ngohlobo lwenhlabathi yendawo, ukujiya kongqimba lwenhlabathi, izimo zezulu kanye nezidingo zendawo. Ngokuvamile, izinhlobo zezitshalo ze-herbaceous endaweni yamanzi kufanele zikhethwe otshanini obumelana nesomiso kanye nezitshalo ze-legume, futhi imbewu yotshani obuxubile kufanele yenziwe ngezinhlobo eziningi (15-20) noma inani elikhulu lembewu (30-50g/m2); izinhlobo zezitshalo zasemanzini kufanele zikhethelwe izindawo ezingaphansi kwamanzi; izinhlobo zezitshalo ezimelana namanzi kufanele zikhethwe ezindaweni ezishintsha izinga lamanzi; ezindaweni ezome kakhulu, izinhlobo zezitshalo ezimelana nesomiso, ezimelana nokushisa, kanye nezinhlobo zezitshalo eziwugwadule kufanele zibekwe kuqala.
