M'mafakitale momwe kuyeza madzi kumakhudzira mikhalidwe yamatope kapena yamatope ambiri—monga ntchito za migodi zokhudzana ndi madzi otayirira okhala ndi mchere komanso minda yaulimi yosamalira madzi oyenda pansi omwe amanyamula tinthu ta dothi—zoyezera madzi oyenda nthawi zambiri sizigwira ntchito bwino. Kutsekeka, kusweka, ndi kuwerengedwa kolakwika ndi misampha yofala, zomwe zimapangitsa kuti ntchito zisayende bwino, kusatsatira malamulo, komanso zoopsa zachilengedwe. Komabe, zoyezera madzi oyenda pansi pa njira yotseguka zimapangidwa kuti zithetse mavutowa: kapangidwe kake kamapangidwa kuti kazigwira madzi oyenda pansi komanso odzaza ndi matope, zomwe zimapangitsa kuti zikhale njira yabwino kwambiri yowunikira migodi ndi madzi oyenda pansi pa nthaka.
Pakati pa mfundo ya ma flow meter otseguka, ma flow meter oyenera kwambiri pamavuto amadzimadzi ndi mfundo yawo yosalowerera kapena yocheperako. Mosiyana ndi ma shutter meter otsekedwa omwe amadalira masensa amkati (omwe amaipitsidwa mosavuta ndi sediment buildup) kapena zigawo zamakina (zomwe zimatha kuwonongeka ndi tinthu tating'onoting'ono), ma shutter meter otseguka amayesa kuyenda kwa madzi m'machubu osapanikizika, otseguka (monga ngalande, ma flume, kapena ma weirs) pogwiritsa ntchito masensa akunja kapena osawonekera bwino. Ukadaulo wamba umaphatikizapo ultrasound (kuyeza mulingo wamadzi kudzera m'mafunde amawu), radar (kugwiritsa ntchito mafunde a wailesi kuti azindikire kutalika kwa pamwamba), ndi laser (kuti atsatire mulingo molondola)—zonsezi zimapewa kukhudzana mwachindunji ndi zigawo zambiri zamadzimadzi zomwe zili ndi sediment. Kapangidwe kameneka kamachotsa zoopsa zotsekeka ndikuchepetsa kusweka, kuonetsetsa kuti kulondola kukuchitika ngakhale madzi ali ndi mchenga wambiri, matope, kapena zinyalala zamchere. Mwachitsanzo, ma ultrasound otseguka meter amagwiritsa ntchito ma transducers omwe amaikidwa pamwamba pa madzimadzi, kutulutsa mafunde omwe amatuluka m'madzi kuti awerengere mulingo (ndipo motero kuchuluka kwa madzi kudzera mu miyeso ya njira yoyesedwa kale)—palibe zigawo zomwe zimamira m'madzimadzi ovunda, palibe chiopsezo cha sensa kuipitsidwa.
Kwa makampani opanga migodi, komwe madzi otayirira komanso olemera ngati matope ndi chinthu chochokera ku ntchito (kuyambira kutsuka miyala mpaka kukonza matope), zoyezera kuyenda kwa migodi yotseguka zimakwaniritsa zosowa zofunika kwambiri pakugwira ntchito komanso chilengedwe. Madzi otayirira m'migodi nthawi zambiri amakhala ndi zinthu zolimba zomwe zimapachikidwa (monga zitsulo zachitsulo kapena fumbi la malasha), zomwe zimatha kuletsa msanga zoyezera migodi zotsekedwa mwa kutseka masensa kapena kuwononga zinthu zamkati. Mosiyana ndi zimenezi, zoyezera migodi yotseguka zimakula bwino m'malo otere: zoyezera zawo zakunja zimakhalabe zopanda matope, ndipo kuthekera kwawo kuthana ndi kuchuluka kwa madzi otayirira (komwe kumachitika nthawi ya migodi, komwe madzi amawonjezeka panthawi yokonza miyala) kumatsimikizira kuyang'anira molondola kutuluka kwa madzi otayirira. Kulondola kumeneku ndikofunikira kwambiri pakutsata malamulo: madera ambiri amafuna kuti migodi inene kuchuluka kwa madzi otayirira ndi milingo ya matope kuti apewe kuipitsidwa kwa mitsinje kapena madzi apansi panthaka. Mwachitsanzo, ntchito yofufuza golide ku Western Australia, idasinthira ku zoyezera migodi yotseguka pogwiritsa ntchito radar kuti iwunikire kutuluka kwa dziwe lotayirira. Mamitawa sanangolimbana ndi madzi oundana kwambiri (omwe kale ankatseka ma meter a makina sabata iliyonse) komanso anapereka deta yeniyeni yomwe inathandiza mgodi kuchepetsa kutuluka kwa zinyalala ndi 22%—kupewa zilango zokwera mtengo komanso kukonza magwiridwe antchito achilengedwe. Kuphatikiza apo, ma meter otseguka ndi osavuta kuyika m'mabowo akanthawi ndi m'mabowo omwe amagwiritsidwa ntchito nthawi zambiri pokumba, zomwe zimapangitsa kuti zikhale zosavuta kusinthasintha kuposa makina okhazikika otsekedwa.
Mu kuyang'anira madzi otuluka m'munda, zoyezera madzi otseguka m'njira yotseguka zimagwira ntchito yofunika kwambiri pakuwongolera madzi mosalekeza komanso kuteteza chilengedwe. Madzi otuluka m'munda pambuyo pa kuthirira kapena mvula—amanyamula matope ambiri, feteleza, ndi mankhwala ophera tizilombo, zomwe zimapangitsa kuti madzi a m'mphepete mwa nyanja apafupi aziwopsezedwa (monga kuwononga nthaka kapena kukokoloka kwa nthaka). Zoyezera madzi zachikhalidwe zimavuta pano: matope amatseka malo olowera, ndipo madzi otuluka m'madzi amasinthasintha (kuyambira mvula yochepa mpaka mvula yambiri) zimapangitsa kuti pakhale kuwerenga kolakwika. Komabe, zoyezera madzi otseguka m'njira yotseguka zimapangidwa kuti zithetse kusinthasintha kumeneku: zimatha kuyeza madzi otsika (monga, kutuluka kwa madzi pambuyo pa kuthirira) ndi madzi otuluka m'madzi ambiri (monga, madzi otuluka m'madzi amvula) molondola mofanana, ndipo masensa awo osalowerera amapewa kuipitsidwa ndi tinthu ta nthaka. Pa famu yayikulu ya chimanga ku Iowa, kuyika zoyezera madzi otseguka m'mitsinje yamadzi m'mitsinje yamadzi kunathandiza alimi kutsatira kuchuluka kwa madzi otuluka m'munda ndikuzindikira madera omwe nthaka ili ndi kukokoloka kwakukulu. Mwa kusintha nthawi yothirira ndikuwonjezera mbewu zophimba m'malo omwe madzi amatuluka m'mitsinje yambiri, famuyo inachepetsa kutayika kwa matope ndi 30% ndikuwonjezera kugwiritsa ntchito bwino madzi—kuchepetsa ndalama zothirira ndi 15%. Pa ntchito zaulimi zomwe zimadalira malamulo okhudza chilengedwe (monga US Clean Water Act), mitayi imaperekanso deta yotsimikizika kuti itsimikizire kuti ikutsatira malire a madzi otuluka.
Ubwino wina waukulu wa ma flow meter open channel m'mafakitale onse awiri ndi wochepa pa zosowa zawo zosamalira. Mu migodi, komwe zida nthawi zambiri zimapezeka m'malo akutali, ovuta kufikako, kukonza ma meter pafupipafupi kumakhala kokwera mtengo komanso kumatenga nthawi. Ma meter otseguka, opanda zida zoyenda pansi pa madzi, amangofunika kuyeretsa masensa akunja nthawi ndi nthawi (osavuta kuchita ndi burashi) ndi kuwerengera pachaka—kuchepetsa ndalama zosamalira ndi 50% poyerekeza ndi ma meter achikhalidwe. Mu ulimi, komwe ma meter amakumana ndi nyengo, mapangidwe olimba (monga zotchingira nyengo ndi zinthu zosagwira dzimbiri) amatsimikizira magwiridwe antchito odalirika mvula, kutentha, kapena kuzizira. Mitundu yambiri imaphatikizaponso zinthu zanzeru, monga kutumiza deta kutali kudzera mu IoT, kulola ogwira ntchito m'migodi kapena alimi kuyang'anira kuchuluka kwa madzi kuchokera pamalo apakati—kusunga nthawi ndikuwongolera kuwoneka bwino kwa ntchito.
Ngakhale kuti zoyezera madzi otseguka zitha kukhala ndi mtengo wapamwamba kwambiri kuposa zoyezera madzi wamba, ubwino wawo wa nthawi yayitali pa migodi ndi kuyang'anira madzi otuluka m'minda ndi ulimi umaposa kwambiri ndalama zomwe zayikidwa. Pa migodi, kuchepetsa ndalama zokonzera, kutsatira malamulo, ndi kuteteza chilengedwe kumatanthauza phindu la ndalama zomwe zayikidwa mkati mwa zaka 2-3. Pa minda, kugwiritsa ntchito bwino madzi, kuchepa kwa kutaya kwa dothi, komanso kuchepetsa ndalama zothirira kumapereka phindu lofanana la ndalama—kuphatikiza phindu lowonjezera la kasamalidwe ka nthaka kokhazikika.
Pamene migodi ndi ulimi zikukumana ndi mavuto ochulukirapo kuti zichepetse kuwonongeka kwa chilengedwe ndikugwira ntchito bwino, zoyezera kuyenda kwa madzi otseguka amadzimadzi oundana/okhala ndi sediment yambiri zakhala zida zofunika kwambiri. Kutha kwawo kuphatikiza kulimba, kulondola, komanso kusasamalira bwino kumawapangitsa kukhala oyenerera bwino mavuto apadera a mafakitale awa. Kaya kuyang'anira migodi yamadzi otayirira kuti ateteze misewu yamadzi kapena kutsatira madzi otayirira a ulimi kuti asunge dothi ndi madzi, zoyezera kuyenda kwa madzi otseguka ndi zambiri kuposa njira yoyezera—ndizofunikira kwambiri pa ntchito zokhazikika. Pa bizinesi iliyonse yokhudzana ndi madzi oundana kapena odzaza ndi sediment, zoyezera izi zimatsimikizira kuti mikhalidwe yovuta sikutanthauza kuti magwiridwe antchito awo ndi ofooka.
