Kwimizi-mveliso yokuhambisa amanzi, iinkqubo zokuhambisa amanzi amdaka zasezidolophini kunye neeprojekthi zokugcina amanzi, uninzi lwemibhobho yamanzi isebenza phantsi kweemeko zemibhobho engagcwaliyo, eyaziwa ngokuba yi-partial pipe flow. Ngokungafaniyo nemibhobho evaliweyo ecinezelweyo egcina ukusebenza kwamanzi apheleleyo, imibhobho yokuhambisa amanzi idla ngokuba namanqanaba olwelo aguquguqukayo, isantya sokuhamba kwamanzi esingazinzanga kunye nomphezulu wamanzi ovulekileyo, okwenza imitha yokuhamba kwamanzi yendabuko yemibhobho evaliweyo ingasebenzi. Imitha yokuhamba kwamanzi yetshaneli evulekileyo yenzelwe ngokukodwa iindawo ezinjalo zokuhamba kwamanzi angaphantsi komhlaba, ifezekisa ukuchaneka.umlinganiselo wokuhamba kwamanzikwipayipi engagcweleyo kwayeitshaneli evulekileyoUkuziqhelanisa kwazo ngendlela ekhethekileyo kuzenza zibe zizixhobo zokulinganisa eziphambili kwiinkqubo zanamhlanje zokujonga amanzi amdaka kunye nemibhobho yamanzi.
Umahluko ophambili phakathi kokulinganisa umjelo ovulekileyo kunye nokulinganisa umbhobho ovaliweyo ukwimeko yokuhamba. Iimitha zemibhobho evaliweyo zixhomekeke kulwelo oluxinzelelweyo lombhobho opheleleyo ukuvelisa imiqondiso yokulinganisa ezinzileyo, kwaye ziya kusilela okanye zivelise iimpazamo ezinkulu xa umbhobho ungazalanga. Ngokwahlukileyo koko, iimitha zokuhamba komjelo ovulekileyo zamkela umgaqo wokulinganisa isantya sendawo, obala isantya sokuhamba ngokukhawuleza ngokufumanisa isantya sokuhamba ngexesha langempela kunye nendawo yokuhamba kwecandelo elinqamlezileyo. Ekubeni inqanaba lolwelo kwimibhobho engagcwaliyo litshintsha rhoqo, icandelo elinqamlezileyo lokuhamba elisebenzayo liyahluka ngokuguquguqukayo. Iimitha zemibhobho evulekileyo zinokuqokelela ngokuzenzekelayo idatha yokuphakama kwenqanaba lolwelo kunye nesantya sokuhamba, kwaye zigqibezele ukubalwa kokuhamba kwexesha langempela ngokusebenzisa ii-algorithms ezakhelwe ngaphakathi, zilungelelanisa ngokugqibeleleyo neempawu eziguquguqukayo zokuhamba kombhobho okungaphelelanga.
Enye yezona meko ziphambili zokusetyenziswa kweemitha zokuhamba kwamanzi ezivulekileyo kukujonga inethiwekhi yamanzi amdaka asezidolophini kunye namanzi emvula. Iipayipi zokuhambisa amanzi zasezidolophini ikakhulu zisebenza ngaphandle kokuhamba kwamanzi ngokupheleleyo unyaka wonke. Umthamo wokuhamba kwamanzi utshintsha kakhulu ngokwexesha lonyaka, imvula kunye nokusetyenziswa kwamanzi ekhaya, nto leyo ebangela ukuba amanqanaba olwelo angazinzile kakhulu kunye nesantya sokuhamba kwamanzi. Iimitha ze-electromagnetic okanye ze-turbine zemveli azikwazi ukusebenza ngokuqhelekileyo kwiindawo ezinjalo. Iimitha zokuhamba kwamanzi ezivulekileyo, ezihlala zixhotyiswe ngee-ultrasonic probes, zilinganisa inqanaba lolwelo ngetekhnoloji ye-ultrasonic echo kwaye zibona isantya sokuhamba kwamanzi nge-Doppler principle. Zisebenza ngokuzinzileyo nokuba umbhobho ugcwele isiqingatha, isithathu sigcwele okanye ukwimeko yokuhamba kwamanzi eguquguqukayo, ziqaphela ukubekwa kweliso okuqhubekayo nokungajongwanga kokukhutshwa kwamanzi amdaka.
Ukukhutshwa kwamanzi amdaka kwimizi-mveliso yenye indawo ebalulekileyo yokusetyenziswa. Iifektri zikhupha amanzi amdaka aguquguqukayo kunye namanzi amdaka angenaxesha, nto leyo ekhokelela ekutshintsheni rhoqo phakathiukuhamba okuphantsi kunye nokuhamba okuphezuluimeko yemibhobho engagcwaliyo. Ukongeza, amanzi amdaka emizi-mveliso aqulathe izinto eziqinileyo ezixhonyiweyo, udaka olucolekileyo kunye nokungcola. Ngethamsanqa, iimitha zokuhamba kwemisele evulekileyo azinanxibelelwano nolwelo kwaye azinazo iindawo ezihamba ngoomatshini. Aziyi kuvalwa okanye zigugiswe yintlenga, kwaye ukuchaneka kwazo kokulinganisa akuchaphazeleki kukungcola okanye ubuninzi bolwelo. Olu buchule bubalaseleyo bokulwa nokuphazamiseka buqinisekisa ukusebenza okuthembekileyo ixesha elide kwiimeko ezinzima zokukhupha amanzi kwimibhobho engagcwaliyo.
Xa kuthelekiswa ne-weir yendabuko kunyeumlinganiselo weflumeiindlela, itshaneli evulekileyo yanamhlanjeiimitha zokuhambaZineengenelo ezicacileyo kwiimeko zemibhobho engaphelelanga. Izakhiwo zokulinganisa zemveli zifuna umahluko ozinzileyo wamanqanaba amanzi kunye neemilo zemijelo eqhelekileyo, ezinzima ukuziqhelanisa nemibhobho emidala ekhoyo kunye neemeko zokuhamba eziguquguqukayo. Ngokwahlukileyo koko, iimitha zemijelo evulekileyo ye-ultrasonic azifuni ukulungiswa kwezakhiwo zemibhobho. Zingafakwa ngokuthe ngqo phezulu kwemibhobho yokukhupha amanzi, zilungele zombini imibhobho engxande neyesangqa. Zinokufakelwa okulula, iindleko zokulungisa eziphantsi kunye nomlinganiselo ophezulu wokujika, zigcina ukuchaneka okuphezulu kokulinganisa nokuba phantsi kweemeko zokuhamba kwamanzi eziphantsi kakhulu kunye neemeko zamanzi angaphantsi.
Ngamafutshane, iimitha zokuhamba kwemisele evulekileyo zenzelwe ngokukodwa imibhobho engagcweleyo kunye nomxhuzulaneiindawo zokuhamba kwamanziZisombulula iindawo zokulinganisa ubunzima benqanaba lolwelo oluguquguqukayo, izinga lokuhamba elingazinzanga kunye nolwelo olungacinezelwanga kwimibhobho yokukhupha amanzi. Zisetyenziswa kakhulu kwimijelo yamanzi amdaka kamasipala, ukujonga amanzi amdaka kwimizi-mveliso kunye nokuchongwa kokugcinwa kwamanzi, zibonelela ngedatha yokuhamba echanekileyo nethembekileyo yokujonga ukhuseleko lokusingqongileyo, izibalo zemithombo yamanzi kunye nolawulo lokusebenza kwemibhobho. Njengezixhobo zokulinganisa eziphambili zokuhamba kwemibhobho engaphelelanga, zidlala indima engenakutshintshwa kulawulo lwanamhlanje lokusingqongileyo kwamanzi ezidolophini nakwimizi-mveliso.
