Indawo: IBrisbane, e-Australia
Enhliziyweni yeBrisbane, eyaziwa njengenye “yamadolobha emvula” ase-Australia, umdanso othambile uvela njalo ngesizini yesiphepho. Njengoba amafu amnyama eqoqana futhi kuqala iculo lamaconsi emvula, uhla lwezilinganiso zemvula luhlangana buthule ukuze luqoqe idatha ebalulekile esekela imizamo yokuphathwa kwamanzi yedolobha kanye nokuhlela amadolobha. Lena indaba ngamaqhawe angadunyiswanga ombuso wemvula—izilinganisi zemvula—kanye nendima yawo ekwakheni ikusasa lamadolobha aphilayo ase-Australia.
Idolobha Lemvula
IBrisbane, enesimo sezulu esishisayo, ithola imvula ejwayelekile yonyaka engaphezu kwamamilimitha ayi-1,200, okwenza ibe ngelinye lamadolobha amakhulu anemvula kakhulu e-Australia. Nakuba imvula iletha impilo emapaki nasemifuleni evundile enikeza idolobha ubuhle bayo, iphinde idale izinselele ezinkulu ekuphathweni kwamadolobha nasekulawulweni kwezikhukhula. Iziphathimandla zendawo zithembele kakhulu kudatha yemvula enembile ukuklama izinhlelo zokukhipha amanzi eziphumelelayo, ukuphatha imithombo yamanzi, nokuvikela imiphakathi ezingozini ezibangelwa yizikhukhula.
Inethiwekhi Yabaqaphi
Ngaphesheya kweBrisbane, amakhulu ezilinganiso zemvula ahlanganiswe ngendlela eyinkimbinkimbi endwangu yedolobha, abekwe ophahleni lwezindlu, ezindaweni zamapaki, ngisho nasezimpambanweni zemigwaqo ezimatasa. Lawa madivayisi alula kodwa ayinkimbinkimbi alinganisa inani lemvula enayo phakathi nesikhathi esithile. Ukufundwa okuqoqwe kusiza izazi zezulu ukuthi zibikezele, zazise abahleli bedolobha, futhi zisize izinsizakalo eziphuthumayo.
Phakathi kwalaba baqaphi kukhona inethiwekhi yama-rain gauge azenzakalelayo aqhutshwa nguHulumeni waseQueensland. Ahlonyiswe ngobuchwepheshe obuthuthukisiwe, la ma-gauge adlulisela idatha yesikhathi sangempela ku-database ephakathi, ebuyekezwa njalo ngemizuzu embalwa. Lapho kufika isiphepho, uhlelo luxwayisa ngokushesha izikhulu zedolobha, luzivumela ukuthi ziqaphe ukuqina kwemvula futhi zilandelele izindawo ezingaba khona zezikhukhula.
“Ngesikhathi sezimvula ezinkulu, umzuzu ngamunye ubalulekile,” kuchaza uDkt. Sarah Finch, isazi sesimo sezulu eNyuvesi yaseQueensland. “Amageyiji ethu emvula ahlinzeka ngolwazi olubalulekile olusisiza ukuthi siphendule ngokushesha, siqinisekise ukuphepha komphakathi kanye nokuvikela ingqalasizinda.”
Usuku Empilweni Yesilinganiso Semvula
Ukuze siqonde umthelela walezi zilinganiselo zemvula, ake silandele uhambo lwe-“Gauge 17,” esinye seziteshi zokulinganisa ezisebenzayo kakhulu edolobheni esiseSouth Bank Parklands. Ntambama ejwayelekile yasehlobo, iGauge 17 imi endaweni ethandwayo yepikiniki, uhlaka lwayo lwensimbi lukhanya ngaphansi kwelanga.
Njengoba ubumnyama bugubuzela idolobha, amaconsi okuqala emvula aqala ukuna. I-funnel yegeji iqoqa amanzi, iwaqondise esilinda sokulinganisa. I-millimeter ngayinye yemvula eqongelelekayo itholwa yinzwa eqopha idatha ngokushesha. Ngesikhashana nje, lolu lwazi luthunyelwa ohlelweni lokuqapha isimo sezulu lwe-Brisbane City Council.
Lapho isiphepho sikhula, i-Gauge 17 iqopha amamilimitha angu-50 amangalisayo ngaphansi kwehora. Le datha ivusa izexwayiso kulo lonke idolobha—iziphathimandla zendawo zihlela izinhlelo zazo zokulawula izikhukhula, zeluleka izakhamuzi ezisezindaweni ezisengozini enkulu ukuba zilungiselele ukuphuma kwabantu okungenzeka.
Ukuzibandakanya Komphakathi
Umthelela wamageyiji emvula udlulela ngale kwengqalasizinda; futhi udlala indima ebalulekile ekubandakanyeni komphakathi kanye nokuqwashisa. UMkhandlu Wedolobha LaseBrisbane uhlala ubamba ama-workshop kanye nezinhlelo zemfundo ukufundisa izakhamuzi ngamaphethini emvula kanye nemiphumela yawo. Abantu bendawo bakhuthazwa ukuthi bafinyelele idatha yemvula yesikhathi sangempela ngohlelo lokusebenza lomphakathi olunikeza imibiko yesimo sezulu enemininingwane, okuhlanganisa nedatha yomlando mayelana nemikhuba yemvula.
“Ukuqonda ukuthi lina kangakanani imvula edolobheni lethu kusisiza ukuba siqonde indawo esihlala kuyo,” kusho umfundisi womphakathi uMark Henderson. “Izakhamuzi zingafunda ukuthi kufanele zilondoloze nini amanzi nokuthi zingazilungiselela kanjani izimvula ezinkulu, zibe abahlanganyeli abakhuthele ekuphatheni izinsiza zethu esabelana ngazo.”
Ukumelana Nesimo Sezulu Nokusungula Izinto Ezintsha
Njengoba ukuguquka kwesimo sezulu kuletha izinselelo ezintsha, iBrisbane ihamba phambili ekusunguleni izinto ezintsha kanye namasu okuzivumelanisa nezimo. Idolobha litshala imali kuma-rain gauge athuthukile akwazi ukulinganisa hhayi nje imvula kuphela kodwa futhi nokugeleza kwamanzi esiphepho kanye namazinga angaphansi komhlaba. Le ndlela ehlanganisiwe ye-hydrology izovumela ukubikezela okungcono kanye nengqalasizinda eqinile.
“Amageyiji emvula ayisiqalo nje,” kuchaza uDkt. Finch. “Sisebenzela uhlelo oluphelele lokuphathwa kwamanzi oluchaza yonke ithonsi, siqinisekise ukuthi iBrisbane ingachuma ngisho naphezu kokungaqiniseki kwesimo sezulu.”
Isiphetho
EBrisbane, lapho imvula iwuphawu lwempilo, amageyiji emvula enza okungaphezu kokulinganisa imvula; abonisa umoya wokuqina kanye nokusungula izinto ezintsha lapho ubhekene nezinselele zemvelo. Njengoba iziphepho zisina, lawa madivayisi alula avikela ikusasa ledolobha, eqondisa ukuthuthuka kwalo libe yindawo yokuhlala yasemadolobheni eqhubekayo. Ngesikhathi esizayo lapho amafu ehlangana ngaphezu kwaleli dolobha eliphilayo, khumbula abaqaphi abathule abasebenza ngokungakhathali ukugcina izakhamuzi zalo ziphephile futhi zinolwazi, kanyekanye.
