Mu buhanga mu nganda, mu mirenge no mu bidukikije, gupima urujya n'uruza rw'amazi adafunze—nk'amazi yanduye mu nganda zitunganya amazi, amazi y'imvura mu miyoboro y'amazi, cyangwa amazi yo kuhira mu miyoboro y'ubuhinzi—bisaba ibikoresho byihariye. Bitandukanye na sisitemu z'imiyoboro ifunze, aho ibyuma bipima amazi bishobora gukoresha umuvuduko cyangwa umuvuduko mu buryo butaziguye, ibyuma bifunguye (bisobanurwa nk'imiyoboro yuzuye igice aho amazi anyura bitewe n'imbaraga rukuruzi) bisaba ikoranabuhanga rijyanye n'imiterere yabyo yihariye. Ibipimo bipima amazi bidafunze byagaragaye nk'igisubizo, bihuza uburyo bwo gukora neza, guhuza no kuramba kugira ngo bigenzure urujya n'uruza rw'amazi muri ibi bice bigoye.
Uburyo Ibipimo by'Ingufu z'Umuyoboro Ufunguye Bikora: Uruhare rw'Inzu z'Umuyoboro n'Izimyamwoto
Mu ishingiro ry'igipimo cy'umuyoboro ufunguye ni ihame ry'ubujyakuzimu bw'ingenzi—aho umuvuduko n'ubujyakuzimu bw'amazi bigera ku mubano uhamye, bigatuma umuvuduko w'amazi ubarwa uhereye ku bujyakuzimu bwonyine. Ibipimo by'umuyoboro ufunguye byishingikiriza ku nyubako nk'imirongo cyangwa ibyuma kugira ngo bikore ubu bujyakuzimu bw'ingenzi, hanyuma bigakoresha ibyuma bipima urugero rw'amazi aturukaho, agahindurwa umuvuduko w'amazi binyuze mu buryo bwashyizweho.
Uruzitiro ni uruzitiro rushyirwa ku muyoboro, rutuma amazi atemba hejuru y’uruti (urugero: rufite ishusho ya V, uruziga rw’impande, cyangwa trapezoidal). Uburebure bw’amazi hejuru y’uruzitiro (umutwe) bufitanye isano itaziguye n’umuvuduko w’amazi, nk’uko bigenwa n’amahame ngenderwaho y’ubuhanga (urugero: ISO 1438/1 cyangwa ASTM D524). Urugero, uruzitiro rw’amazi rufite ishusho ya V ni rwiza ku mikoreshereze y’amazi make nk’imigezi mito, mu gihe uruzitiro rw’impande rukora neza ku miyoboro myinshi y’amazi mu miyoboro y’umujyi.
Flume ni umuyoboro ufite ishusho yihariye ugabanya amazi, ukihutisha umuvuduko kandi ugatanga itandukaniro rigaragara mu rugero rw'amazi hagati y'ibice byo hejuru (aho amazi yinjira) n'aho amazi yinjira. Imiterere isanzwe irimo flume za Parshall (zikoreshwa cyane mu mazi yanduye) na flume za Palmer-Bowlus (ku miyoboro izengurutse itemba igice cyuzuye). Flume zikunze gukundwa kuruta ibiti byo mu mazi birimo imyanda cyangwa imyanda, kuko imiterere yazo igabanya kuziba kw'amazi.
Kugira ngo bapime ingano y'amazi, ibipimo bigezweho by'amazi bifunguye bikoresha ibikoresho nka transducers za ultrasonic (zidakora ku mazi yanduye, zikwiriye amazi yanduye), transducers z'umuvuduko (ziri munsi y'amazi, zikwiriye amazi meza), cyangwa sensors za radar (zidahura n'ingaruka mbi z'ikirere). Ibi bikoresho bitanga amakuru ku cyuma gitanga amakuru, gikoresha ikigereranyo cya weir/flume kugira ngo kibare umuvuduko w'amazi mu gihe nyacyo.
Porogaramu z'ingenzi: Aho Open Channel Flowmeters Excel
Ibipimo by'imiyoboro ifunguye ni ingenzi cyane mu nzego aho imiyoboro ikoreshwa n'imbaraga rukuruzi ari yo yiganje:
- Gutunganya amazi yanduye mu Mujyi: Bagenzura amazi yanduye (amazi mabi) n'amazi yasukuwe (yasukuwe), bagenzura ko amategeko agenga amazi asohoka kandi bakanoza uburyo bwo kuyatunganya. Amafuru ya Parshall akunze kugaragara cyane hano, kuko afata amazi yuzuyemo ibintu bikomeye adasibangana kenshi.
- Gucunga amazi y'imvura: Imijyi ikoresha ayo mazi mu gukurikirana amazi asohoka mu miyoboro y'amazi, ikarinda imyuzure imenyesha abakora amazi ko amazi ashobora kwiyongera cyane. Aha niho hongerwa ibikoresho byo mu bwoko bwa ultrasound bidakora, kuko amazi y'imvura akunze gutwara imyanda ishobora kwangiza ibikoresho biri munsi y'amazi.
- Ubuhinzi: Mu buryo bwo kuhira, ibipimo by'amazi bipima ikwirakwizwa ry'amazi mu mirima, bigafasha abahinzi kunoza imikoreshereze no kubahiriza amabwiriza agenga uburenganzira bw'amazi. Inzu zikoreshwa mu miyoboro mito, mu gihe amafuru akoreshwa mu miyoboro minini.
- Igenzura ry’ibidukikije: Bakurikirana amazi atemba mu migezi, mu migezi no mu bishanga kugira ngo bige ku mutungo w’amazi, ubuzima bw’urusobe rw’ibinyabuzima, cyangwa ingaruka z’amazi asohoka mu nganda. Imiterere ya ultrasonic igendanwa yemerera gushyirwaho by’agateganyo kugira ngo hakoreshwe ubushakashatsi mu murima.
Ibyiza n'imbogamizi: Guhitamo ikoranabuhanga rikwiye
Ibipimo by'imiyoboro y'amazi bifunguye bitanga inyungu zidasanzwe kuri sisitemu zidakandamizwa:
- Guhuza n'imimerere: Bikorana n'imiterere itandukanye y'imiyoboro (urukiramende, uruziga, trapezoidal) n'ingano, kuva ku miyoboro mito kugeza ku miyoboro minini.
- Uburyo bwo Kugabanya Ikiguzi: Inzu zo ku rukuta n'amatara nta bice byimuka, bigabanya ikiguzi cyo kubungabunga ugereranije n'ibipimo bya mekanike. Ibyuma bidakora ku rukuta (ultrasonic, radar) birinda kwangirika kw'amazi akoreshwa mu gukurura.
- Iyubahirizwa ry’amategeko: Bujuje ibisabwa mpuzamahanga mu bijyanye n’ukuri, bigatuma bizewe mu gutanga raporo z’amategeko (urugero, uruhushya rwo gukoresha amazi yanduye ya EPA).
Ariko, bafite aho badashobora gusuzuma:
- Ibisabwa mu gushyiraho: Inzu n'amatara bikenera guhuza neza no guhindura imiyoboro kugira ngo habeho imiterere nyayo y'ubujyakuzimu. Inyubako zidashyizweho neza zishobora gutuma habaho amakosa yo gupima.
- Guhangana n'imyanda: Inzu zikunze kuzunga amababi, imyanda, cyangwa imyanda, bigatuma amazi atemba kandi bigahindura imiterere y'amazi. Gusukura buri gihe ni ngombwa ahantu handuye.
- Imbogamizi ku rujya n'uruza rw'amazi: Buri gishushanyo mbonera cy'umugezi cyangwa icyuma gikora neza mu rujya n'uruza runaka. Inyubako nini cyane zishobora kubura ubuziranenge mu rujya n'uruza ruto, mu gihe iz'ubuto zishobora kuzura.
Udushya mu gupima imikorere y'imiyoboro ifunguye
Iterambere riherutse ryazamuye imikorere mu bihe bigoye:
- Utwuma tw’ubwenge: Utwuma tw’ikoranabuhanga rigezweho rya ultrasonic na radar birimo uburyo bwo kwisukura (urugero, gusukura umwuka) kugira ngo hirindwe kwangirika mu mikoreshereze y’amazi yanduye. Binahuzwa na platform za IoT zo kugenzura kure no gusesengura amakuru.
- Ibipimo by'ibipimo byinshi: Hari ubwoko bumwe buhuza gupima amazi n'ibipima ubuziranenge bw'amazi (urugero: pH, turbidity), bitanga amakuru yose yerekeye ibidukikije cyangwa ibikorwa byo kuyatunganya.
- Sisitemu zigendanwa: Ibipimo byoroheje kandi bikoresha batiri bifite umurongo ntarengwa bitanga uburenganzira bwo gukwirakwiza by'agateganyo ahantu kure, bikaba byiza mu gukurikirana byihutirwa cyangwa mu bushakashatsi bw'igihe gito.
Umwanzuro
Ibipimo by'amazi bifunguye bigira uruhare runini mu gucunga sisitemu z'amazi zidafite umuvuduko, bitanga ibipimo byizewe aho ikoranabuhanga rikoresha imiyoboro ifunze ritagenda neza. Mu gukoresha imiyoboro, ibyuma bitanga amazi, n'ibikoresho bigezweho, bipima neza, biramba, kandi bigakoresha neza amafaranga mu bikorwa bitandukanye kuva ku gutunganya amazi yanduye kugeza ku bushakashatsi ku bidukikije. Uko ibikorwa remezo bigenda birushaho kuba bibi n'ibura ry'amazi rirushaho kwiyongera, uruhare rwabyo mu kunoza ikoreshwa ry'umutungo no kugenzura ko amategeko yubahiriza amategeko ruzagenda rwiyongera - bigatuma biba inkingi ikomeye mu gucunga amazi ya none.
