Mumaindasitiri uko kuyerwa kwemvura kunosanganisira mamiriro emvura ine madhaka kana kuti ine sediment yakawanda—senge mabasa ekuchera migodhi anobata nemvura ine tsvina ine zvicherwa neminda yekurima inotarisira mvura inoyerera inotakura ivhu—ma flow meter echinyakare anowanzo kundikana kupa mashandiro akavimbika. Kuvharika, kukweshwa, uye kuverenga kusina kururama idambudziko rakajairika, zvichikonzera kusashanda zvakanaka, kusatevedzera mitemo, uye njodzi dzezvakatipoteredza. Open channel flow meter, zvisinei, yakagadzirwa kuti ikunde matambudziko aya: dhizaini yavo yakagadzirirwa kubata ma turbid uye sediment fluids, zvichiita kuti ive mhinduro yakakwana yekuongorora migodhi uye mvura inoyerera mukurima.
Chinonyanya kukosha kwemamita ekuyerera kwemvura munzvimbo dzine mvura yakaoma ndechekuti haapindi mvura zvakanyanya kana kuti haasviki panzvimbo ine mvura yakawanda. Kusiyana nemamita ekuyera mvura akavharwa anovimba nemasensa emukati (anosvibiswa nyore nyore ne sediment buildup) kana zvikamu zvemakanika (zvinowanzo pera kubva muzvinhu zvinokwenya), mamita ekuyera mvura akazaruka anoyera kuyerera kwemvura mumigero isina kumanikidzwa (yakadai semigero, flumes, kana weirs) achishandisa masensa ekunze kana asina kuratidzwa zvakanyanya. Matekinoroji akajairika anosanganisira ultrasonic (kuyera mwero wemvura kuburikidza nemafungu eruzha), radar (kushandisa mafungu eredhiyo kuona kukwirira kwenzvimbo), uye laser (yekutevera mwero chaiwo)—zvose izvi zvinodzivirira kusangana zvakananga nezvikamu zvine sediment zvakanyanya zvemvura. Dhizaini iyi inobvisa njodzi dzekuvharika uye inoderedza kukwenya, ichivimbisa kururama nguva dzose kunyangwe mvura ine huwandu hwakawanda hwejecha, silt, kana marara emaminerari. Semuenzaniso, mamita ekuyera mvura akazaruka anoshandisa ma transducers akaiswa pamusoro pemvura, achiburitsa mafungu anosvetuka kubva mumvura kuti averenge mwero (uye nokudaro mwero wekuyerera kwemvura kuburikidza nehukuru hwe channel hwakatarwa kare)—hapana zvikamu zvakanyudzwa mumvura ine turbid, hapana njodzi yekusvibiswa kwe sensor.
Kune indasitiri yemigodhi, uko mvura ine madhaka, ine mvura yakawanda sediment iri chibereko chekushanda (kubva pakusuka simbi kusvika pakugadzirisa tsvina), mita yekuyerera kwemvura yakavhurika inotarisa zvinodiwa zvakakosha pakushanda uye nharaunda. Mvura yakasviba yemugodhi inowanzova nehuwandu hwakawanda hwezvinhu zvakasimba zvakasungirirwa (zvakadai sesimbi yesimbi kana guruva remarasha), izvo zvinogona kukurumidza kudzima mita yemapaipi akavharika nekuvhara masensa kana kupwanya zvikamu zvemukati. Mita yemagetsi yakavhurika, zvakasiyana, inobudirira munzvimbo iyi: masensa avo ekunze anoramba asina kuunganidzwa kwetsvina, uye kugona kwavo kubata mwero wekuyerera kwakasiyana-siyana (unowanzoonekwa mumigodhi, uko kushandiswa kwemvura kunowedzera panguva yekugadzirisa simbi) kunoita kuti pave nekutariswa kwakarurama kwekubuda kwemvura yakasviba. Kururama uku kwakakosha pakutevedzera mitemo: matunhu mazhinji anoda kuti migodhi itaure huwandu hwemvura yakasviba uye huwandu hwetsvina kudzivirira kusvibiswa kwenzizi kana pasi pevhu. Basa rekuchera goridhe muWestern Australia, semuenzaniso, rakachinjira kumamita emagetsi akavhurika akavakirwa paradar kuti ritarise kubuda kwemvura mudziva rakavhurika. Mamita haana kungotsungirira mvura ine madhaka akawanda (iyo yaimbovhara mamechanical metres vhiki rega rega) asiwo akapa data renguva chaiyo rakabatsira mugodhi kuderedza kuburitswa kwematope ne22% - kudzivirira faindi dzinodhura uye kuvandudza mashandiro ezvakatipoteredza. Pamusoro pezvo, mamita emagetsi akavhurika ari nyore kuisa mumigero yenguva pfupi uye nzira dzinowanzo shandiswa mukuchera, zvichiita kuti zvive nyore kuchinjika kupfuura masisitimu emapaipi akavharika.
Mukuongorora mvura inoyerera muminda, mita dzekuyerera kwemvura dzinoshanda zvikuru mukuchengetedza mvura inoyerera uye kuchengetedzwa kwezvakatipoteredza. Mvura inoyerera kubva muminda mushure mekudiridza kana kunaya kwemvura inonaya, inotakura huwandu hwakawanda hwedota, fetereza, nemishonga yezvipembenene, zvichikonzera njodzi kunzira dzemvura dziri pedyo (dzakadai se eutrophication kana ivhu rinokukurwa). Mata echinyakare anonetsa pano: dota rinovhara nzvimbo dzinopinda mvura, uye kuyerera kwakasiyana-siyana (kubva pakunaya kwemvura shoma kusvika pakunaya kwemvura yakawanda) kunotungamira pakuverengwa kusina kururama. Mata emvura anobuda muminda, zvisinei, akagadzirirwa kubata nekuchinja uku: anogona kuyera kuyerera kushoma (semuenzaniso, kubuda kwemvura mushure mekudiridza) uye kuyerera kwakanyanya (semuenzaniso, kuyerera kwemvura inoyerera) nekururama kwakaenzana, uye masensa avo asingapindi anodzivirira kusvibiswa kubva muvhu. Kune purazi guru rechibage muIowa, kuisa mita dzemvura dzinobuda muminda dzinobatsira varimi kuti vatevedzere huwandu hwemvura inoyerera uye kuona nzvimbo dzine ivhu rakawandisa. Nekugadzirisa hurongwa hwekudiridza nekuwedzera zvirimwa zvekufukidza munzvimbo dzinoyerera mvura yakawanda, purazi rakaderedza kurasikirwa kwedota ne30% uye rakavandudza kushanda zvakanaka kwemvura—kuderedza mari yekudiridza ne15%. Pamabasa ekurima anoenderana nemitemo yezvakatipoteredza (yakadai seUS Clean Water Act), mita idzi dzinopawo ruzivo rwakasimba kuratidza kuti mvura inoyerera zvakanaka.
Chimwe chinhu chakakosha che open channel flow metres kumaindasitiri ese ari maviri ndechekuti zvinodiwa zvavo zvekugadzirisa zvishoma. Mumigodhi, uko michina inowanzo kuwanikwa munzvimbo dziri kure, dzakaoma kusvika, kugadziriswa kwemamita kakawanda kunodhura uye kunotora nguva. Open channel metres, isina zvikamu zvinofamba zvakanyudzwa mumvura, inoda kucheneswa kwemasensa ekunze nguva nenguva (kunoitwa zviri nyore nebhurashi) uye kuenzaniswa kwegore negore—kuderedza mari yekugadzirisa kusvika ku50% zvichienzaniswa nemamita echinyakare. Mukurima, uko mamita anosangana nemamiriro ekunze, magadzirirwo akasimba (akadai semakontena anodzivirira mamiriro ekunze nezvinhu zvinodzivirira ngura) anovimbisa kushanda kwakavimbika mumvura, kupisa, kana kutonhora. Mamodheru mazhinji anosanganisirawo maficha akangwara, akadai sekutumira data kure kuburikidza neIoT, zvichibvumira vashandi vemigodhi kana varimi kutarisa mwero wekuyerera kubva panzvimbo iri pakati—kuchengetedza nguva uye kuvandudza kuona kwekushanda.
Kunyange zvazvo mita dzemvura dzakavhurika dzichigona kuva nemutengo wakakwira wepamberi kupfuura mita dzemakanika, mabhenefiti adzo enguva refu ekuchera nekutarisa mvura inoyerera mumigodhi yekurima anopfuura zvakanyanya mari iyi. Kumigodhi, kuderedzwa kwemari yekugadzirisa, kutevedzera mitemo, uye kuchengetedzwa kwezvakatipoteredza zvinoreva kudzoka kwemari inoiswa mukati memakore maviri kusvika matatu. Kumapurazi, kushandiswa kwemvura zvakanaka, kuderedzwa kwekurasikirwa nedhaka, uye kuderedzwa kwemari yekudiridza zvinopa pundutso yakafanana yemari—pamwe nerubatsiro rwekutarisira ivhu nenzira inochengetedza nguva dzose.
Sezvo migodhi nekurima zvichitarisana nekumanikidzwa kuri kukura kwekuderedza kukanganisa kwezvakatipoteredza uye kushanda zvakanaka, mita dzekuyerera kwemvura dzakavhurika dzemvura dzine turbid/high-sediment dzave zvishandiso zvinokosha. Kugona kwavo kusanganisa kugara kwenguva refu, kururama, uye kusachengetedza kwakaringana kunoita kuti vakwanise zvakakwana nematambudziko akasiyana emaindasitiri aya. Kungave kutarisa mvura yakasviba yekuchera kuti vadzivirire nzira dzemvura kana kutevera mvura inoyerera mukurima kuchengetedza ivhu nemvura, mita dzekuyerera kwemvura dzakavhurika dzinopfuura mhinduro yekuyera—idzo dzinotungamira mashandiro anochengetedza nguva dzose. Kune chero bhizinesi ripi zvaro rinobata nemvura dzine turbid kana sediment, mita idzi dzinoratidza kuti mamiriro ezvinhu akaoma haafanire kureva kushanda kwakakanganisika.
