Aho uherereye: Brisbane, Ositaraliya
Hagati ya Brisbane, uzwi cyane nk'umwe mu “mijyi y'imvura yo muri Ositaraliya,” imbyino nziza igaragara buri gihe cy'imvura. Mugihe ibicu byijimye byegeranijwe hamwe na korari yimvura itangiye, ibipimo byinshi byimvura bikusanya bucece gukusanya amakuru akomeye ashigikira imicungire y’amazi n’igikorwa cyo gutegura imijyi. Iyi ni inkuru ivuga ku ntwari zitavuzwe mu karere k'imvura - igipimo cy'imvura - n'uruhare rwabo mu gutegura ejo hazaza h'imijyi ikomeye ya Ositaraliya.
Umujyi w'imvura
Brisbane, hamwe n’ikirere cyayo gishyuha, ihura n’imvura igereranywa buri mwaka ya milimetero zirenga 1.200, ikaba imwe mu mijyi minini itose yo muri Ositaraliya. Mugihe imvura izana ubuzima muri parike ninzuzi zitanga umujyi mwiza, binatera ibibazo bikomeye mubuyobozi bwimijyi no kurwanya imyuzure. Abayobozi b'inzego z'ibanze bashingira cyane ku makuru y’imvura kugira ngo bashushanye uburyo bunoze bwo gufata amazi, gucunga umutungo w’amazi, no kurinda abaturage ingaruka ziterwa n’umwuzure.
Urusobe rw'abarinzi
Hirya ya Brisbane, ibipimo by'imvura amagana bikozwe mu mwenda w'umujyi, bishyirwa hejuru y'inzu, parike, ndetse no mu masangano menshi. Ibi bikoresho byoroshye ariko binini bipima ingano yimvura igwa mugihe runaka. Ibisomwa byakusanyirijwe bifasha abahanga mu bumenyi bw'ikirere guhanura, kumenyesha abategura umujyi, no gufasha ubutabazi.
Muri abo barinzi harimo urusobe rw'ibipimo by'imvura byikora bikoreshwa na guverinoma ya Queensland. Hamwe nibikoresho byikoranabuhanga bigezweho, ibi bipimo byohereza amakuru nyayo kububiko rusange, bugezwaho buri minota mike. Iyo igihuhusi kibaye, sisitemu iramenyesha byihuse abayobozi b'umugi, ibemerera gukurikirana ubukana bw'imvura no gukurikirana ahantu hashobora kuba umwuzure.
Dogiteri Sarah Finch, inzobere mu bumenyi bw'ikirere muri kaminuza ya Queensland abisobanura agira ati: “Mu gihe cy'imvura nyinshi, buri munota ubara. Ibipimo by'imvura bitanga amakuru y'ingenzi adufasha gutabara vuba, kubungabunga umutekano rusange no kubungabunga ibikorwa remezo. ”
Umunsi Mubuzima bwa Gauge Imvura
Kugira ngo dusobanukirwe n'ingaruka z'ibi bipimo by'imvura, reka dukurikire urugendo rwa “Gauge 17,” imwe muri sitasiyo zipima cyane umujyi ziherereye muri Parike ya Banki y'Amajyepfo. Ku gicamunsi gisanzwe, Gauge 17 ihagarara kuri sentinel ahantu hazwi cyane picnic, ikariso yacyo ikayangana munsi yizuba.
Mugihe umwijima utwikiriye umujyi, ibitonyanga byambere byimvura bitangira kugwa. Umuyoboro wa gauge ukusanya amazi, ukayerekeza muri silinderi yo gupima. Buri milimetero yimvura yegeranya igaragazwa na sensor ihita yandika amakuru. Mu kanya gato, aya makuru yoherejwe muri sisitemu yo kugenzura ikirere cya Njyanama y'Umujyi wa Brisbane.
Iyo umuyaga ukabije, Gauge 17 yanditse milimetero 50 zitangaje mu isaha imwe. Aya makuru akangurira abantu kumenya umujyi wose - abayobozi b'inzego z'ibanze bakangurira gahunda zabo zo guhangana n’umwuzure, bagira inama abaturage bo mu turere tw’ibyago byinshi kwitegura kwimuka.
Uruhare rwabaturage
Ingaruka zipima imvura irenze ibikorwa remezo; bafite kandi uruhare runini muguhuza abaturage no kubimenya. Njyanama y'Umujyi wa Brisbane ihora ikora amahugurwa na gahunda z'uburezi bigisha abaturage ibijyanye n'imvura n'ingaruka zabyo. Abenegihugu barashishikarizwa kubona amakuru yimvura nyayo binyuze muri porogaramu rusange itanga amakuru arambuye y’ikirere, harimo amakuru y’amateka ku bijyanye n’imvura.
Umwarimu w’abaturage Mark Henderson agira ati: "Gusobanukirwa n’imvura igwa mu mujyi wacu bidufasha kwishimira ibidukikije dutuyemo." Ati: “Abaturage barashobora kwiga igihe cyo kubungabunga amazi n'uburyo bwo gutegura imvura nyinshi, bakagira uruhare rugaragara mu gucunga umutungo dusangiye.”
Kurwanya ikirere no guhanga udushya
Kubera ko imihindagurikire y’ikirere itera ibibazo bishya, Brisbane iri ku isonga mu guhanga udushya no kurwanya imihindagurikire y'ikirere. Umujyi urimo gushora imari mu bipimo by'imvura bigezweho bishobora gupima imvura gusa ariko no gutemba kw'amazi y'imvura n'amazi yo mu butaka. Ubu buryo bukomatanyije kuri hydrology buzafasha guhanura neza nibikorwa remezo bihamye.
Dr. Finch asobanura ati: “Ibipimo by'imvura ni intangiriro. Ati: “Turimo gukora ku buryo bunoze bwo gucunga neza amazi bugira uruhare runini kuri buri gitonyanga, kugira ngo Brisbane ishobora gutera imbere nubwo haba hari ikibazo cy’ikirere.”
Umwanzuro
I Brisbane, aho imvura iranga ubuzima, ibipimo by'imvura ntibikora gusa gupima imvura; bikubiyemo umwuka wo kwihangana no guhanga udushya mu guhangana n’ibibazo by’ibidukikije. Mugihe imvura iguye, ibyo bikoresho byoroshye birinda ejo hazaza h'umujyi, bikayobora ubwihindurize muri oasisi irambye. Igihe gikurikiraho ibicu bizateranira hejuru yuyu mujyi ufite imbaraga, ibuka abarinzi batuje bakora ubudacogora kugirango abawutuye babungabunge umutekano kandi babimenyeshejwe, igitonyanga kimwekimwe.
