Kwa zaka zambiri, makoma achikhalidwe ndi ma flume akhala maziko a kuyeza kuyenda kwa madzi m'mitsinje, ngalande, machitidwe amadzi otayira, ndi zotuluka m'mafakitale. Zipangizozi zimagwira ntchito motsatira mfundo yosavuta: kuchepetsa kuyenda kwa madzi kuti apange kulumpha kwamadzi koyezeka, ndi kuchuluka kwa madzi komwe kumawerengedwa kutengera kuya kwa madzi. Komabe pamene zosowa za kasamalidwe ka madzi zikukulirakulira—motsogozedwa ndi kukula kwa mizinda, kusintha kwa nyengo, ndi malamulo okhwima okhudza chilengedwe—makoma achilengedwe ndi ma flume amavumbula zofooka zazikulu. Amakonda kutsekeka, amafuna malo ambiri oyika, ndipo amapereka deta yochedwa komanso yochepa. Masiku ano, mita yanzeru yotseguka yamagetsi ikuwoneka ngati njira ina yosinthira, kudutsa zoletsa za zida zachikhalidwe kuti zifotokozenso momwe madzi amayezera molondola, kulumikizana, komanso kusinthasintha.
Mawero ndi ma flume akale amakumana ndi mavuto omwe amalepheretsa kugwira ntchito kwawo masiku ano. Mawerowa, okhala ndi mapangidwe awo okhala ndi denga lakuthwa kapena lalikulu, amasonkhanitsa mosavuta zinyalala, matope, ndi zinthu zoyandama—zomwe zimapezeka kwambiri mu njira zoyeretsera madzi akuda kapena madzi amvula—zomwe zimalepheretsa kuyenda kwa madzi ndi kusinthasintha kwa madzi. Ma flume, ngakhale kuti sakutha kutsekeka, amafunika kuyikidwa molondola ndi magawo owongoka akumtunda ndi akumunsi, zomwe zimapangitsa kuti zikhale zosatheka panjira zopapatiza kapena zomangamanga zokonzedwanso. Zipangizo zonsezi sizili ndi luso lotha kupeza deta nthawi yeniyeni: ogwiritsa ntchito ayenera kulemba kuya kwa madzi pamanja, nthawi zambiri zomwe zimapangitsa kuti azindikire mochedwa zolakwika za madzi monga kutuluka kapena kukwera kwa madzi. M'malo osinthasintha—monga mitsinje yokhala ndi madzi osiyanasiyana kapena kutuluka kwa madzi m'mafakitale komwe kumasintha kuchuluka kwa madzi—zipangizo zakale zimavutika kusunga kulondola, chifukwa kuwongolera kwawo kumakhazikika pamikhalidwe inayake ya madzi. Kwa maboma ndi mafakitale, zoletsa izi zikutanthauza kuti sagwiritsa ntchito bwino madzi, satsatira zilolezo zachilengedwe, komanso nthawi yotsika mtengo yokonza.
Mamita otseguka anzeru amathetsa zolakwika izi kudzera muukadaulo watsopano wozindikira komanso kuphatikiza kwa digito, kufotokozeranso zomwe zingatheke poyesa kuyenda kwa madzi. Mosiyana ndi makoma ndi ma flume, mamita awa safuna kuchepetsedwa kwa madzi, kuchotsa zoopsa zotsekeka ndi zoletsa zoyika. Amagwiritsa ntchito njira zapamwamba zodziwira madzi—kuphatikizapo ma ultrasound, radar, ndi acoustic Doppler—kuti ayesere kuya kwa madzi, liwiro, ndi kuchuluka kwa madzi mwachindunji, ngakhale m'njira zamatope, zosaya, kapena zodzaza ndi zinyalala. Ma ultrasonic models amatulutsa mafunde amawu kuti azindikire kukwera kwa madzi, pomwe ma radar meters amalowa mu fumbi, chifunga, kapena thovu kuti apereke kuwerenga kodalirika munyengo yovuta. Ma Acoustic Doppler current profilers (ADCPs) amayesanso kwambiri, kujambula ma velocity profiles kudutsa njira yonse kuti apeze kulondola kosayenera, ngakhale m'mitsinje kapena ngalande zosawoneka bwino.
Chomwe chimasiyanitsa mita yanzeru yotseguka ndi kuphatikiza kwawo kulumikizana kwa IoT ndi luntha la deta, kusintha muyeso wa kuyenda kuchokera ku ntchito yopanda ntchito kupita ku chida chogwira ntchito choyang'anira. Mita iyi imatumiza deta yeniyeni ku nsanja zozikidwa pamtambo kapena machitidwe owongolera am'deralo, zomwe zimathandiza ogwira ntchito kuyang'anira kuchuluka kwa kuyenda kwa madzi patali kudzera pa mapulogalamu am'manja kapena ma dashboard a pa intaneti. Pa malo oyeretsera madzi otayira, izi zikutanthauza machenjezo achangu okhudza kuchuluka kwa madzi mwadzidzidzi komwe kungalepheretse njira zoyeretsera. Pa malo oyeretsera madzi, deta yeniyeni imalola kuyang'anira kwamphamvu kugawa madzi a ngalande, kuonetsetsa kuti ulimi ndi mabanja zikupezeka mofanana. Malo opangira mafakitale amapindula ndi malipoti odziyimira pawokha, kupangitsa kuti kutsatira malamulo otulutsa madzi kukhale kosavuta popanga zolemba zolondola, zolembedwa nthawi. Ma mita ambiri anzeru amaphatikizanso ma algorithms ophunzirira makina, omwe amasanthula deta yakale kuti alosere momwe madzi amayendera - kuthandiza ogwira ntchito kuyembekezera kusintha kwa madzi amvula kapena njira zamafakitale ndikusintha magwiridwe antchito mwachangu.
Kusinthasintha ndi ubwino wina waukulu wa mita yotsegulira njira zanzeru, zomwe zimawathandiza kuti azikula bwino m'malo osiyanasiyana komwe mipanda yachikhalidwe ndi ma flume zimalephera. Amapangidwa kuti agwirizane ndi njira iliyonse yotseguka, kuyambira mitsinje yopapatiza yamadzi amvula ndi mitsinje yayikulu mpaka ngalande zotulutsira madzi m'mafakitale ndi ngalande zothirira. Kapangidwe kake kakang'ono, kosasokoneza kamalola kuyika kosavuta popanda kusokoneza kayendedwe ka madzi komwe kulipo kapena kufunikira ntchito zazikulu zapakhomo - kofunikira kwambiri pakukonzanso zomangamanga zakale. Mita yotsegulira njira zanzeru imasinthanso malinga ndi kusinthasintha kwa chilengedwe: imadzipangira yokha kusintha kwa kutentha kwa madzi, kutayikira, ndi mawonekedwe a njira, ndikusunga kulondola pamlingo waukulu wamadzi (kuyambira madontho ochepa mpaka kusefukira kwakukulu). M'malo akutali kapena ovuta - monga njira zothirira zakumidzi kapena kutuluka kwa madzi amvula m'mphepete mwa nyanja - mitundu yogwiritsa ntchito batri imagwira ntchito kwa zaka zambiri popanda kukonza, pomwe njira zogwiritsa ntchito mphamvu ya dzuwa zimapereka kuwunika kokhazikika m'malo omwe si a gridi.
Kuyeza kwa kayendedwe ka madzi komwe kumaperekedwa ndi ma smart open channel meters kumawonjezera phindu kwa ogwiritsa ntchito komanso chilengedwe. Mwa kuchotsa kusonkhanitsa deta pamanja ndikuchepetsa zosowa zosamalira, amachepetsa ndalama zogwirira ntchito ndi 40% poyerekeza ndi ma wairs achikhalidwe. Kulondola kwawo—nthawi zambiri mkati mwa ±2% ya kuchuluka kwa madzi enieni—kumatsimikizira kulipira kolondola kwa kugwiritsa ntchito madzi, kugawa bwino zinthu, komanso kutsatira miyezo ya chilengedwe. Kwa madera omwe akukumana ndi kusowa kwa madzi, ma smart metres amathandizira kuyesetsa kosamalira malo pozindikira kutayikira kwa madzi kapena zomangamanga zomwe zimatuluka madzi. M'madera omwe kusefukira kwa madzi kumafalikira, deta ya madzi nthawi yeniyeni imathandizira machitidwe ochenjeza msanga, kuthandiza kuchepetsa kuwonongeka kwa katundu ndikuteteza miyoyo. Kafukufuku wa Water Environment Federation adapeza kuti kugwiritsa ntchito kwambiri ma smart open channel metres kwachepetsa kutayika kwa madzi kosapindulitsa ndi 18% m'machitidwe a m'matauni ndikukweza mitengo yotsatirira zilolezo zotulutsira madzi m'mafakitale ndi 30%.
Kuyambira pa kayendetsedwe ka madzi a m'mizinda ndi kuwongolera njira zamafakitale mpaka kuyang'anira zachilengedwe ndi kuthirira ulimi, ma smart open channel meters akusintha momwe timayezera ndikuwongolera kuyenda kwa madzi. M'malo oyeretsera madzi akuda, amayang'anira kulowa ndi kutuluka kwa madzi kuti akonze njira zoyeretsera madzi ndikuletsa kusefukira kwa madzi. M'mitsinje ndi mitsinje, amapereka deta yofunika kwambiri yotetezera zachilengedwe, kutsatira kuchuluka kwa madzi kuti athandizire malo okhala nsomba ndi ubwino wa madzi. M'malo opangira mafakitale, amaonetsetsa kuti akutsatira malire otulutsira madzi pomwe akukonza momwe madzi amagwiritsidwira ntchito popanga zinthu. Ngakhale m'mikhalidwe yovuta kwambiri—monga madera a m'mphepete mwa nyanja omwe nthawi zambiri amakhala ndi mphepo yamkuntho kapena madera omwe ali ndi chilala—ma smart meters amapereka magwiridwe antchito odalirika, kutsimikizira kulimba kwawo poyang'anizana ndi kusintha kwa nyengo.
Pamene kufunika kwa madzi padziko lonse lapansi kukukulirakulira ndipo malamulo okhudza chilengedwe akukhwima kwambiri, zoletsa za makoma achikhalidwe ndi ma flume sizikuvomerezedwanso. Mamita otseguka anzeru amatanthauziranso muyeso wa kayendedwe ka madzi mwa kuphatikiza kulondola, kulumikizana, komanso kusinthasintha kukhala yankho limodzi. Amapatsa mphamvu ogwira ntchito ndi chidziwitso cha nthawi yeniyeni, amachepetsa ndalama zogwirira ntchito, komanso amathandizira kasamalidwe ka madzi kokhazikika—zonsezi pamene akugonjetsa zopinga zomwe zalepheretsa zida zachikhalidwe kwa zaka zambiri.
Mu ulendo wopita ku kasamalidwe ka madzi kanzeru komanso kokhazikika, mita yotsegulira njira zanzeru ndi yoposa kukweza ukadaulo—ndi kusintha kwa njira yodziwira zinthu. Mwa kupitirira mipanda yachikhalidwe, zimatsimikizira kuti kuyeza kwa madzi kungakhale kolondola, kogwira mtima, komanso kogwirizana ndi zosowa za madera ndi mafakitale amakono. Pamene mabungwe ambiri akulandira zipangizo zatsopanozi, tikuyandikira tsogolo lomwe madzi amayendetsedwa mwanzeru, zinthu zimatetezedwa, ndipo madera akutukuka mogwirizana ndi dziko lapansi.
