Kwimisebenzi yemizi-mveliso, kamasipala, kunye neyokusingqongileyo—apho ulwelo luhamba ngemijelo engavalwanga (njengemilambo, imijelo yamanzi amdaka, imijelo yamanzi amdaka, okanye imijelo yokunkcenkceshela)—ukulinganisa ukuhamba ngokuchanekileyo kubalulekile kulawulo lwezixhobo, ukuthobela imithetho, kunye nokusebenza kakuhle. Ngokungafaniyo neemitha zemibhobho evaliweyo (umz., iimodeli ze-ultrasonic okanye ze-electromagnetic) ezixhomekeke kwiinkqubo zolwelo ezivaliweyo, iimitha zokuhamba kwemijelo evulekileyo zenzelwe ukulinganisa ukuhamba kwimijelo evulekileyo, eqhutywa ngumxhuzulane, ukujongana nemingeni eyahlukileyo yokuhamba kwamanzi okungavalwanga—njengamanqanaba amanzi aguquguqukayo, ukwakheka kwedaka, kunye nokuguquguquka kwendalo. Ukususela ekujongeni ukukhutshwa kwamanzi amdaka kwizityalo zonyango ukuya ekuphuculeni ukunkcenkceshela kumasimi ezolimo, ezi mitha ziye zaba zizixhobo ezibalulekileyo kumashishini axhomekeke kwidatha ethembekileyo ukulawula izixhobo zamanzi. Ngokudibanisa iteknoloji eguquguqukayo kunye noyilo oluqinileyo, iimitha zokuhamba kwemijelo evulekileyo azisombululi nje kuphela ubunzima bokulinganisa ukuhamba kwamanzi okungavalwanga kodwa zikwaqhuba uzinzo, ukonga iindleko, kunye nokuthobela—ziqinisa indima yazo kulawulo lwamanzi lwanamhlanje.
Ukusebenza kweemitha zokuhamba kwemisele evulekileyo kuvela kwimigaqo yazo yokusebenza eyenzelwe wena, echaza indlela ezihamba ngayo izinto ezivulekileyo. Ngokungafaniyo neenkqubo zemibhobho evaliweyo (apho izinga lokuhamba linxulunyaniswa noxinzelelo kunye nobubanzi bemibhobho), ukuhamba kwemisele evulekileyo kuxhomekeka kwizinto ezimbini ezibalulekileyo: indawo enqamlezileyo yemisele kunye nesantya solwelo. Ukulinganisa oku, iimitha zemisele evulekileyo zihlala zisebenzisa enye yeendlela ezimbini eziphambili: ii-weirs okanye ii-flumes, ezidityaniswe ne-level sensor (umz., i-ultrasonic, i-radar, okanye i-pressure-based). Ii-Weirs zii-notches (umz., ezimile okwe-V, ezingxande) ezifakwe kwi-channel; njengoko amanzi ehamba phezu kwe-weir, ukuphakama kwamanzi ngaphezu kwe-notch (eyaziwa ngokuba "yintloko") kuhambelana nesantya sokuhamba, esibalwa yi-level sensor kusetyenziswa iifomyula ezilinganisiweyo kwangaphambili. Ii-Flume, ngokwahlukileyo, ziinxalenye ezixineneyo zemisele ezikhawulezisa ukuhamba; i-level sensor ilinganisa ukuphakama kwamanzi kwindawo ethile kwi-flume, kwaye izinga lokuhamba livela kubudlelwane phakathi kokuphakama kunye nesantya. Olu yilo lujongana nomceli mngeni omkhulu wokuhamba kwamanzi avulekileyo—ukuguquguquka: nokuba umjelo uthwala amanzi amdaka anomthamo omncinci okanye amanzi emvula anomthamo omkhulu, iingcango kunye neeflume zenza ipateni yokuhamba kwamanzi ehambelanayo nelinganiswayo, ukuqinisekisa ukuchaneka nokuba amanqanaba amanzi atshintshatshintsha. Kwiziko lokunyanga amanzi amdaka likamasipala, oku kuthetha ukulandelela ngokuthembekileyo ukukhutshwa kwamanzi amdaka ukuze kuhlangatyezwane nemigaqo yokusingqongileyo; kumlimi, kuqinisekisa ukunkcenkceshela ngokuchanekileyo ukuze kuthintelwe ukunkcenkceshela izityalo kakhulu.
Ngaphaya kokuchaneka, iimitha zokuhamba kwemisele evulekileyo zibonelela ngokuqina kokusebenza kwiindawo ezinzima okanye ezingaqikelelweyo. Ngokungafaniyo neemitha zemibhobho evaliweyo ezibuthathaka ezinokonakala yinkunkuma okanye inkunkuma, iimodeli zemisele evulekileyo zakhiwe ukuze zisetyenziswe ngendlela eqinileyo: ii-weirs kunye nee-flumes zihlala zenziwe ngezinto ezimelana nokugqwala (umz., intsimbi engatyiwayo, i-fiberglass, okanye ikhonkrithi) ukumelana neekhemikhali, imitha ye-UV, okanye inkunkuma erhabaxa (umz., isanti ekuchithekeni kwamanzi kwezolimo). Ii-level sensors nazo zenzelwe ukuqina: ii-ultrasonic sensors, umzekelo, zifakelwa ngaphezulu kwamanzi (akukho kudibana ngqo) ukuthintela ukungcoliswa yi-algae okanye inkunkuma, ngelixa ii-radar sensors zisebenza kwiimeko ezinothuli, ezinemvula, okanye ezinomkhenkce—ukuqinisekisa ukusebenza konyaka wonke. Ukugcinwa kucwangciswe ngokulinganayo: ngokungafaniyo nee-mechanical meters ezifuna ukutshintshwa kwenxalenye rhoqo, iinkqubo zemisele evulekileyo zifuna kuphela ukujonga rhoqo (umz., ukucoca iindawo zenkunkuma, ii-calibrating level sensors ngonyaka). Kumsebenzi wokwemba, odla ngokujongana namanzi agcwele inkunkuma, oku kuthetha ukuba akukho xesha lininzi lokuphumla; kwisithili sokunkcenkceshela esikude, kususa isidingo sokutyelela rhoqo indawo ukuze kulungiswe izixhobo ezibuthathaka.
Iimitha zokuhamba kwemisele evulekileyo zikwabonelela ngokuguquguquka kunye nokwandiswa, nto leyo eyenza ukuba zifaneleke kwiindlela ezahlukeneyo kumashishini. Zingenziwa ngokwezifiso ukuze zilingane nayo nayiphi na itshaneli—ukusuka kwimisele emincinci yezolimo (ububanzi obuziisentimitha ezimbalwa) ukuya kwimisele emikhulu yemizi-mveliso (ububanzi obuziimitha ezili-10+)—kwaye zilungelelaniswe kwiintlobo ezahlukeneyo zolwelo, kubandakanya amanzi acocekileyo, amanzi amdaka, amanzi emvula, kwanamanzi amdaka. Olu kuguquguquka lubalulekile kumashishini aneemfuno ezahlukeneyo: iiarhente zokusingqongileyo, umzekelo, zisebenzisa iimitha zemisele evulekileyo ukujonga ukuhamba komlambo ukuze kuqikelelwe izikhukula; izityalo zamandla zixhomekeke kuzo ukulinganisa ukungena kwamanzi abandayo avela emachibini; kwaye ii-oyile zokucoca ziyisebenzisa ukulandelela ukukhutshwa kwamanzi amdaka ukuthintela ungcoliseko. Ukongeza, iimitha zemisele evulekileyo zanamhlanje zidityaniswa neenkqubo ezikrelekrele: izinzwa zamanqanaba zinokuthumela idatha yexesha langempela kwiiplatifomu ze-IoT ngokusebenzisa uqhagamshelo olungenazingcingo (iLoRaWAN, iselfowuni) okanye olunentambo, okuvumela ukujonga kude kunye nezilumkiso ezenzekelayo. Kwinkampani yamanzi elawula iitshaneli ezininzi zokunkcenkceshela, oku kuthetha ukubeka idatha kwindawo enye ukuze kuphuculwe ukusasazwa kwamanzi; kumzi-mveliso, kwenza kube lula ukwazisa ngoko nangoko ukuba amazinga okuhamba adlula imida yomthetho—ukuphepha izohlwayo kunye nomonakalo kwindalo.
Njengoko ukunqongophala kwamanzi kwihlabathi liphela kunye nemithetho yokusingqongileyo iba ngqongqo ngakumbi, iimitha zokuhamba kwamanzi ezivulekileyo ziye zavela njengesisombululo esizinzileyo nesinokumelana nekamva sokulinganisa ukuhamba kwamanzi okungathintelwanga. Ukukwazi kwazo ukusingatha iimeko eziguquguqukayo, ukumelana neemeko ezinzima, kunye nokudibana netekhnoloji ekrelekrele kuzenza zibe yimfuneko kwimibutho efuna ukulawula izixhobo zamanzi ngokufanelekileyo nangokuhambelanayo. Nokuba zisetyenziselwa ukukhusela iinkqubo zendalo (ngokujonga impilo yomlambo), ukunciphisa inkunkuma (ngokuphucula ukunkcenkceshela), okanye ukuqinisekisa ukuthotyelwa kwemithetho (ngokulandelela ukukhutshwa kwamanzi kwimizi-mveliso), ezi mitha zingqina ukuba ukulinganiswa kokuhamba kwamanzi avulekileyo akufuneki kube nzima—okanye kungathembeki. Kwihlabathi apho ulawulo lwamanzi olunoxanduva lubaluleke kakhulu, iimitha zokuhamba kwamanzi ezivulekileyo zingaphezulu nje kwezixhobo—zingamaqabane ekuqhubeni uzinzo, ukugqwesa kokusebenza, kunye nokhuseleko lwezixhobo zexesha elide. Kuyo nayiphi na imboni esebenza ngeenkqubo zolwelo ezingathintelwanga, ukutyala imali kwimitha yokuhamba kwamanzi evulekileyo akusiyonto nje yokukhetha—kukuzibophelela ekulawuleni amanzi okusebenzayo, okuvumelanayo, nokuzinzileyo.
