Vhura chiteshimita dzekufambaDzinoita basa rakakosha pakuyera kuyerera kwemvura munzvimbo dzisina kumanikidzwa dzakadai senzizi, migero yekudiridza, madhireni emvura yemvura, uye nzira dzemvura yakasviba dzemaindasitiri. Kugona kwavo kuchinjika uye kuchinjika kwakaita kuti dzive dzinokosha munzvimbo dzakasiyana-siyana dzenzvimbo uye dzemaindasitiri. Pazasi pane zvidzidzo zvakakosha zvinoratidza mashandisirwo adzo chaiwo pasi rese.
1. Kutarisira Mafashamo muNetherlands: Doppler Radar Flowmeters
Netherlands, nyika iri pasi ine njodzi huru yekubatwa nemafashamo, inoshandisa maDoppler radar flowmeters epamusoro munhepfenyuro yayo yakakura yenzizi nemigwagwa. MuRhine-Meuse delta, masensa eradar asingabatanidzi vanhu (semuenzaniso, Teledyne RD Instruments' FlowTrack II) akaiswa pamabhiriji nemakomba kuti ayere kumhanya kwekuyerera kwemvura panguva yezviitiko zvemadutu. Mamita aya anopa data rakakosha kumamodheru ekufanotaura mafashamo, zvichibvumira zviremera kuti zvishandise masisitimu ekunyevera nekukurumidza uye kuronga mhinduro dzenjodzi. Semuenzaniso, panguva yemafashamo eEurope e2021, ma radar flowmeters muMaas River akabatsira kufanotaura huwandu hwemvura ne ±2% chaiyo, zvichibvumira maguta kuti abve munzvimbo dzine njodzi zvakanyanya nekukurumidza.
2. Kushanda Nesimba Kwekudiridza muAustralia:Mamita eChiteshi cheUltrasonic Akavhurika
Munzvimbo dzekurima dzakaoma muAustralia, kushomeka kwemvura kunoda kutarisirwa kwakanyatsojeka kwekudiridza. Murray-Darling Basin, nzvimbo huru inogadzira chikafu, inoshandisama flowmeter e ultrasonic akavhurika(semuenzaniso, YSI's 6600V2) yakabatana nemaflume ekuyera kupararira kwemvura mumigero yekudiridza. Mamita aya, akaiswa pamigero yemvura nepamigero yemigero, anotarisa mwero wekuyerera kwemvura ne ±1% chaiyo, zvichiita kuti varimi vatevedzere mitemo yekugoverwa kwemvura uye vaderedze marara. Semuenzaniso, chidzidzo che2022 chakaitwa neDhipatimendi reNSW rePrimary Industries chakaratidza kuti ma ultrasonic metres akaderedza kushandiswa kwemvura zvisina kunaka ne15% mumapurazi edonje, zvichiita kuti goho rezvirimwa riwedzere kunaka ukuwo richichengetedza zviwanikwa zvishoma.
3. Kutarisa Mvura Yakasviba Mumaindasitiri muGermany: Mamita Emagetsi Akavhurika Mugero
Mafekitori ekugadzira ekuGermany, akazvipira kutevedzera mitemo yakasimba yezvakatipoteredza, anovimba nema electromagnetic open channel flowmeters (semuenzaniso, Endress+Hauser's Promag OC) kuti aongorore kuburitswa kwemvura yakasviba. Pafekitori huru yemotokari muBavaria, mamita aya anoiswa mumigero yakagadzirwa nekongiri kuti aone mwero wekuyerera kwemvura yakasviba uye conductivity isati yagadziriswa. Kugona kwemamita kubata zvinhu zvakasimba zvakanyanya (semuenzaniso, simbi dzakachekwa, mafuta) uye kupa data renguva chaiyo kumasangano ezvakatipoteredza kunoita kuti pave nekutevedzera mirairo yeEU's Water Framework. Muna 2020, sisitimu iyi yakaona kuwedzera kamwe kamwe kwehuwandu hwezvinhu zvakasvibiswa, zvichikonzera kugadziriswa nekukurumidza uye kudzivirira chiitiko chinogona kuitika chekusvibiswa kwerwizi.
4. Kutarisirwa kweMaguta eDutu reMadutu muUnited States: Acoustic Doppler Velocity Meters
Maguta akaita seLos Angeles, anowanzosangana nemafashamo emvura uye mvura inoyerera mumaguta, anoshandisa ruzha rwemagetsiMamita ekumhanya kweDoppler (ADV)(semuenzaniso, SonTek's Argonaut-X) mumadhireni emvura yemvura inonaya uye mabheseni ekuchengetedza mvura. Midziyo iyi inotakurika, inoiswa panguva yemvura zhinji, inoyera kumhanya kwemvura nekudzika kwayo mumigero yakavhurika nehunyanzvi hwe sub-millimeter. Muna 2023, Los Angeles Bureau of Sanitation yakashandisa data reADV kuti ivandudze mashandiro emagedhi ekudzora mafashamo, ichideredza mafashamo emigwagwa ne22% munzvimbo dzine njodzi huru. Pamusoro pezvo, mita iyi inobatsira kuongorora huwandu hwemvura inosvibisa mumvura inoyerera, ichitungamira mapurojekiti ekutsvaira mumigwagwa uye ekuchengetedza nharaunda.
5. Kushanda Nesimba Kwemagetsi Emvura muBrazil: Yakavakirwa paWeirMaflowmeter
Munharaunda yeAmazon muBrazil, madhamu emagetsi emvura akadai seBelo Monte anoshandisa ma "weir-based open channel flowmeters" kuyera kuyerera kwemvura ne "spillway". Ma "Parshall flumes" ane ma "pressure transducers" (semuenzaniso, Hach's FPI-2000) anoshandiswa kuverenga kuburitswa kwemvura ne ±3% chaiyo, zvichiita kuti turbine ishande zvakanaka uye kuburitswa kwemvura munzvimbo inonaya mvura. Ongororo yakaitwa muna 2021 neEletrobras, kambani yemagetsi yenyika yeBrazil, yakaratidza kuti kuyerwa kwemvura kwakanyatsojeka kwakaderedza nguva yekushanda kweturbine ne10%, zvichiwedzera kugadzirwa kwesimba pagore ne50 GWh - zvakakwana kupa simba kudzimba 25,000.
6. Tsvagiridzo yeZvipenyu zveRwizi muIndia: Laser Doppler Anemometry (LDA)
MuRwizi rweGanges, vaongorori vanobva kuIndian Institute of Technology (IIT) Kanpur vanoshandisa laser Doppler anemometry (LDA) kudzidza maitiro ekuyerera kwemvura uye kutakurwa kwedhaka mumigero yakavhurika. Kuyera kweLDA kusingapindire kunobatsira kuratidza kuti tsvina nezvinovaka muviri zvinopararira sei, zvichibatsira mukuchengetedza mhuka dziri munjodzi dzakadai seGanges river dolphin. Muchirongwa cha2022, data reLDA rakaratidza kuti kuchera jecha kwakachinja kumhanya kwekuyerera kwemvura munzvimbo dzakakosha dzekuberekesa, zvichiita kuti pave nemitemo yakaoma yekuchera.
Mhedziso
Kubva kuma deltas anowanzo sangana nemafashamo kusvika kumapurazi asina mvura, mita dzemvura dzakavhurika dzave dzakakosha kunekutarisira zviwanikwa zvemvura, kuona kuti nharaunda inotevedzera mitemo yezvakatipoteredza, uye kutsigira mashandiro emaindasitiri. Zvidzidzo izvi zvepasi rose zvinoratidza kugona kwazvinoita: Doppler radar yekupindura mafashamo nekukurumidza, ma ultrasound sensors ekurima kusina mvura yakawanda, uye ma electromagnetic metres ekutarisira mashandiro emaindasitiri. Sezvo shanduko yemamiriro ekunze ichiwedzera matambudziko ekutarisira mvura, kururama uye kuvimbika kwema open channel flowmeters zvichawedzera kukosha mukuchengetedza ecosystems nenharaunda dzevanhu pasi rese.
