Vhura chiteshimita dzekufambainoita basa guru muzvikamu zvakasiyana-siyana zvemaindasitiri, zvakatipoteredza, uye zvemadhorobha muJapan, uko kuyerwa kwakarurama kwemvura mumigero isina kumanikidzwa—yakadai senzizi, migero, migero yemvura, uye migero yakavhurika—kwakakosha. Mamiriro ekunze akasiyana eJapan, kusanganisira nzvimbo yayo ine makomo, nzvimbo dzakasimba dzemaguta, uye kusakwanisa kubatwa nemadutu nemvura zhinji, zvinoita kuti kuyerwa kwemvura kwakavimbika kuve kwakakosha pakutarisira zviwanikwa zvemvura, kudzivirira njodzi, uye kushanda zvakanaka kwemaindasitiri.
Mukutarisira mvura mumaguta,ma flowmeter enzira yakavhurikaZvinoshandiswa zvakanyanya muhurongwa hwemvura inoyerera mumadhorobha. Maguta ekuJapan, mazhinji acho akavakirwa panyika yakaderera kana pamhenderekedzo, anotarisana nematambudziko anogara achiitika kubva pakunaya kwemvura yakawanda uye mafashamo anogona kuitika. Michina yekufambisa mvura inoiswa mumadhireni emvura inoyerera nemvura inoyerera inopa ruzivo rwechokwadi rwehuwandu hwemvura inoyerera, zvichibvumira vakuru vakuru kutarisa kugona kwemvura inoyerera uye kupa yambiro dzekutanga panguva yezviitiko zvemamiriro ekunze akaipisisa. Semuenzaniso, muTokyo network yakakura yemvura inoyerera pasi pevhu, zvishandiso izvi zvinobatsira kudzora kuyerera kwemvura inonaya munzizi nemakungwa, zvichideredza njodzi yemafashamo emaguta. Pamusoro pezvo, zvinoshandiswa muzviteshi zvekurapa mvura yakasviba kuyera kuyerera kwetsvina mumigero yakavhurika, zvichiita kuti maitiro ekurapa agadziriswe kuti abate huwandu hwakasiyana-siyana.
Chikamu chekurima, icho chiri musimboti wehupfumi hwemaruwa muJapan, chinovimba zvakanyanya nema flowmeter enzira yakavhurikayekudiridza. Nekushaikwa kwevhu rinorimwa uye kunyanya kushandiswa kwemvura nemazvo, varimi vekuJapan vanovimba nekuyera kwakarurama kwemvura inoyerera mumigero yekudiridza inopa minda yemupunga, minda yemiriwo, uye minda yemichero. Michina yemagetsi inobatsira kudzora kupararira kwemvura, ichiva nechokwadi chekuti zvirimwa zvinowana huwandu hwakakwana—zvakakosha pakuwedzera goho ukuwo zvichichengetedza mvura, kunyanya munzvimbo dzine dambudziko rekusanaya kwemvura. Munzvimbo dzakadai seHokkaido, uko kurima kukuru kuri kubudirira, zvishandiso izvi zvinobatsira mukurima kunochengetedza nharaunda nekudzivirira kudiridza zvakanyanya uye kuderedza marara emvura.
Kugadzirwa kwemagetsi emvura, chinhu chakakosha musanganiswa wesimba rinogona kuvandudzwa muJapan, kunobatsirwawo nema flowmeter enzira yakavhurika. Zvivakwa zvakawanda zvemagetsi emvura muJapan zvinoshandisa mvura inobva munzizi nematangi, inofambiswa nemumigero yakavhurika kuti ifambise maturbine. Ma flowmeter akaiswa mumigero iyi anoyera huwandu hwemvura inopfuura nepakati, zvichipa data rakakosha pakugadzira magetsi zvakanaka. Nekutarisa mwero wekuyerera kwemvura, vanoshanda vanogona kugadzirisa kubuda kweturbine kuti ienderane nekuwanikwa kwemvura, vachiona kuti kugadzirwa kwesimba kwakanaka uku vachichengetedza kuenzana kwezvakatipoteredza munzizi. Izvi zvakakosha zvikuru muJapan, uko magetsi emvura anofanira kushanda pamwe chete nemamwe mashandisirwo emvura, akadai semvura yekunwa uye hove.
Mukuongorora zvakatipoteredza,ma flowmeter enzira yakavhurikaZvinoshandiswa kutevedzera kuyerera kwemvura munzizi nenzizi dzechisikigo, zvichitsigira kuedza kuchengetedza nharaunda dzemumvura. Kuzvipira kweJapan kuchengetedza nharaunda kunosanganisira kutarisa hutano hwenzira dzayo dzemvura, idzo dzine marudzi akasiyana-siyana akadai sesalmon netrout. Michina yekuongorora mafambiro emvura inobatsira kuona kana huwandu hwemvura hwakakwana kuchengetedza nzvimbo dzakanaka dzekugara, kunyanya munguva yekusanaya kwemvura kana mushure memapurojekiti ezvivakwa zvakaita sekuvakwa kwemadhamu. Zvinobatsirawo pakuyera kuburitswa kwetsvina yemumaindasitiri mumigero yakavhurika, zvichiona kuti mitemo yakasimba yezvakatipoteredza inotevedzwa kudzivirira kusvibiswa kwemvura inobuda.
Mashandisirwo emaindasitiri muJapan, kunyanya mukugadzira nekugadzirisa, anoshandisawo ma "open channel flowmeters". Semuenzaniso, muma "paper mills" nema "pulp mills", anoshandisa mvura yakawanda, michina iyi inoyera kuyerera kwemvura mu "open channels" dzinoshandiswa kushambidza zvinhu zvisina kugadzirwa kana kutakura marara. Saizvozvowo, muma "food processing firms" - akadai seaya anogadzira soy sauce, miso, kana zvigadzirwa zvehove - ma "flowmeters" anoongorora kuyerera kwemvura mu "drainage", achivimbisa kuti mvura yakasviba inobatwa zvakanaka uye inosangana nezvinodiwa nemitemo. Kugona kwavo kushanda mumamiriro ezvinhu akaoma, kusanganisira ma "dust" kana "water levels" akasiyana, kunoita kuti vasave vakakosha munzvimbo idzi.
Chekupedzisira, mukudzivirira nekuderedza njodzi,ma flowmeter enzira yakavhurikaZvishandiso zvakakosha. Kugona kweJapan kubatwa nemadutu nemvura zhinji zvinoreva kuti kuongorora mwero wekuyerera kwenzizi kwakakosha pakufanotaura nekuita mafashamo. Michina yekufambisa mvura yakaiswa munzizi nedzinoyerera mvura inotumira data kunzvimbo dzekutarisa dzedunhu, uko inoongororwa kuti ifanotaura huwandu hwemvura uye ipe mazano ekubvisa mvura. Muzviitiko zvepashure penjodzi, inobatsirawo kuongorora kukanganiswa kwemafashamo pamigero yemvura, zvichibatsira mukuedza kudzoreredza njodzi uye kugadzirisa zvivakwa zvakakuvara.
Muchidimbu, ma "open channel flowmeters" akakosha muJapan.kutarisira mvura, kurima, kugadzira simba, uye kuchengetedzwa kwezvakatipoteredza. Kugona kwavo kupa data rakarurama uye rakavimbika mumamiriro akasiyana-siyana kunotsigira kuedza kwenyika kuenzanisa budiriro nekugara kwenguva refu, kuve nechokwadi chekuti zviwanikwa zvemvura zvinoshandiswa nemazvo ukuwo zvichichengetedza nharaunda nenharaunda.
