Mita yekuyerera kwechiteshi yakavhurikazvakakoshazviridzwayekuyera mwero wekuyerera kwemvura mumigero yemhepo yakavhurika senge nzizi, migero, uye madhireni emvura yakasviba emaindasitiri. Hunhu hwavo hwakagadzirirwa kusangana nezvinodiwa zvemashandisirwo aya ehurongwa hwakavhurika, zvichiita basa rakakosha muminda yakasiyana-siyana senge manejimendi emvura, kutarisa nharaunda, uye kudzora mashandiro emaindasitiri.
1. Kuchinja-chinja muChannel Geometries
Chimwe chezvinhu zvakakosha zvemita yekuyerera kwechiteshi yakavhurikaikodzero yadzo yekuchinjika kumhando dzakasiyana dzemigero nehukuru. Dzinogona kushandiswa zvinobudirira mumigero ine mativi mana inowanikwa mumichina yekudiridza, nzizi dzechisikigo dzine mativi mana, uye kunyange mumigero yemvura ine chimiro chedenderedzwa. Miyero yekuyerera yakagadzirwa nemagadzirirwo chaiwo, senge ayo akavakirwa pamadziro emvura nemagetsi, akagadzirwa kuti ashande nemagadzirirwo chaiwo ejometri. Semuenzaniso, madziro ane mativi mana akakodzera migero ine mativi mana akaenzana, nepo flume yeParshall inogona kugadziriswa kuti ikwane migero yakasiyana ye trapezoidal kana mativi mana. Kugona uku kunobvumira kushandiswa kwakapararira munzvimbo dzakasiyana-siyana dzakavhurika dzemigero.
2. Sarudzo dzeKuyera Dzisingapindire
Vazhinjimita yekuyerera kwechiteshi yakavhurikainopa nzira dzekuyera dzisingapindi mvura, izvo zvinobatsira zvikuru. Mita yekuyerera yeUltrasonic yakavhurika, semuenzaniso, inogona kuiswa pamusoro pemvura kana pamativi emugero. Inoshandisa mafungu eruzha kuyera kudzika kwemvura uye, mune dzimwe nguva, kumhanya kwekuyerera. Iyi nzira isingapindi mvura inoreva kuti mita haikanganisi kufamba kwechisikigo kwemvura. Inoderedza njodzi yekukuvadzwa kwemita kubva mumvura inoyerera, kunyanya mumigero ine kumhanya kwakanyanya kana inotakura marara. Pamusoro pezvo, kuiswa kusingapindi mvura kunowanzo kurumidza uye kunodhura zvakanyanya, sezvo zvisingade kudzima kuyerera kana kuita shanduko huru kumugero.
3. Kururama Kwakanyanya Mumamiriro Akasiyana-siyana
Mita yekuyerera kwechiteshi yakavhurikadzakagadzirirwa kupa zviyero zvakarurama kunyangwe mumamiriro ezvinhu akaoma. Munzizi, uko mwero wekuyerera unogona kusiyana zvakanyanya nekuda kwemvura inonaya, chando chakanyunguduka, kana kuburitswa kwedhamu rekumusoro, mita dzekuyerera kwemagetsi dzakavhurika dzinogona kuyera kumhanya kwemvura inofambisa mvura. Nekushandisa mutemo waFaraday we electromagnetic induction, mita idzi dzinogona kutsanangura shanduko mukumhanya kwekuyerera uye nzvimbo yechikamu, zvichikonzera kuverenga kwemwero wekuyerera kwakavimbika. Munzira dzemvura yakasviba dzemaindasitiri, uko mvura inogona kunge iine zvinhu zvakamiswa kana kuti ine makemikari akasiyana-siyana, mita dzekuyerera kwemvura dzinobva kuDoppler dzinogona kuyera kumhanya kwekuyerera nekuona kushanduka kwemafungu e ultrasonic anoonekwa kubva muzvikamu zvakamiswa. Izvi zvinogonesa kuyerwa kwekuyerera kwakarurama pasinei nehunhu hwakaoma hwemvura.
4. Kutarisa Nguva Yechokwadi uye Kuenderera Mberi
Mazhinji emamita ekuyerera kwemvura emazuva ano akavhurika anokwanisa kuongorora nguva nenguva. Anowanzo shongedzerwa nemasensa nemidziyo yekunyora data inogona kutumira data rehuwandu hwekuyerera kwemvura nguva nenguva. Izvi zvakakosha pamashandisirwo akadai sekudzora mafashamo, uko data renguva chaiyo pamusoro pehuwandu hwekuyerera kwemvura murwizi rakakosha pakufanotaura huwandu hwemafashamo uye kupa yambiro panguva yakakodzera. Mukutarisira zviwanikwa zvemvura, kutarisa nguva nenguva kwekuyerera kwemvura mumigero kunobatsira mukuvandudza kugoverwa kwemvura yekudiridza nedzimwe nzira dzekushandisa. Kugona kupa ruzivo rwenguva dzose kunobvumirawo kuongororwa kwemafambiro enguva refu ekuyerera kwemvura, izvo zvakakosha muzvidzidzo zvezvakatipoteredza nekuronga zvivakwa.
5. Kugara kwenguva refu uye Kuramba Nzvimbo Dzakaoma
Mita yekuyerera kwechiteshi yakavhurikadzinoda kugara kwenguva refu sezvo dzichiwanzosangana nemamiriro ekunze akaoma. Dzakavakwa kuti dzikwanise kutsungirira kusiyana kwekupisa, hunyoro, uye kusvibiswa nemvura nezuva. Semuenzaniso, ma "flow metres" akaiswa munzizi dzekunze kana mumigero anogona kusangana nekuchinja kukuru kwekupisa pakati pemwaka. Ma "meter" akagadzirwa nezvinhu zvinodzivirira ngura, zvakaita sesimbi isingatsvi kana mamwe mapurasitiki, anogona kutsungirira kuparadzwa nemvura, kunyanya mumigero yemvura yetsvina yemaindasitiri uko mvura yacho inogona kunge iine makemikari. Pamusoro pezvo, dzakagadzirirwa kutsungirira kukanganiswa kwemvura inoyerera uye chero marara angave ari mumigero, zvichiita kuti ishande kwenguva refu.
6. Mutengo - Kubudirira muZvikero Zvakasiyana
Mita yekuyerera kwechiteshi yakavhurikainopa mhinduro dzinoshanda dzemutengo wekuyerwa kwekuyerera kwemvura muzviyero zvakasiyana. Pamashandisirwo madiki, akadai sekuyera kuyerera kwemvura mugomba rekudiridza riri kumashure, mapimita ekuyerera emhando yepropeller ari nyore uye asingadhuri anogona kushandiswa. Mamita aya ari nyore kuisa nekugadzirisa, zvichipa nzira inodhura yekuyera kuyerera kwemvura. Pamwero mukuru, munzizi huru kana mumafekitori makuru ekuchenesa mvura yetsvina, masisitimu ekuyera kuyerera kwemvura akanyanya kuomarara uye anodhura anogona kudiwa. Zvisinei, mabhenefiti enguva refu ekuyera kuyerera kwemvura kwakarurama, akadai sekuvandudzwa kwekutarisira zviwanikwa zvemvura, kuderedzwa kwekukanganisa kwezvakatipoteredza, uye kuwedzera kushanda zvakanaka kwemafekitori, zvinoita kuti mari ishandiswe. Kubudirira kwemari yese yemapimita ekuyerera kwemvura akavhurika kuri mukukwanisa kwawo kupa data rinokosha pamutengo unonzwisisika, zvichienderana nezvinodiwa zvekushandisa.
Mukupedzisa,mita yekuyerera kwechiteshi yakavhurikaZvine hunhu hwakasiyana hunozviita kuti zvive zvakakosha pakuyera kuyerera kwemvura mumasisitimu akavhurika. Kushanduka-shanduka kwadzo, sarudzo dzisingapindiri, kururama kwadzo, kugona kwadzo kutarisa panguva chaiyo, kugara kwenguva refu, uye kushanda zvakanaka kwemari zvinobatsira mukushandiswa kwadzo munzvimbo dzakasiyana-siyana uye kushandiswa kwezvakatipoteredza.
