Indawo: IBrisbane, eOstreliya
Embindini weBrisbane, owaziwa njengenye "yezixeko zemvula" zaseOstreliya, umdaniso othambileyo uvela rhoqo ngexesha leemvula. Njengoko amafu amnyama eqokelelana kwaye kuqala isandi samaconsi emvula, uluhlu lweegeyiji zemvula luhlangana buthule ukuze luqokelele idatha ebalulekileyo exhasa ulawulo lwamanzi lwesixeko kunye nemizamo yokucwangcisa idolophu. Eli libali malunga namaqhawe angadunyiswanga ommandla wemvula—iigeyiji zemvula—kunye nendima yawo ekubumbeni ikamva lezixeko ezinomdla zaseOstreliya.
Isixeko seMvula
IBrisbane, enemozulu yayo eshushu, ifumana imvula ephakathi yonyaka engaphezu kwe-1,200 millimeters, nto leyo eyenza ibe yenye yezona zixeko zinkulu zimanzi kakhulu eOstreliya. Nangona imvula izisa ubomi kwiipaki eziluhlaza kunye nemilambo enika isixeko ubuhle bayo, ikwabangela imingeni ebalulekileyo kulawulo lwedolophu kunye nolawulo lwezikhukula. Amagunya asekuhlaleni axhomekeke kakhulu kwidatha echanekileyo yemvula ukuyila iinkqubo zokuhambisa amanzi eziphumelelayo, ukulawula imithombo yamanzi, kunye nokukhusela uluntu kwiingozi ezibangelwa zizikhukula.
Inethiwekhi yabaGcini
Kuyo yonke iBrisbane, amakhulu eegeyiji zemvula zilukiwe ngendlela entsonkothileyo kwilaphu lesixeko, zibekwe eluphahleni lwezindlu, kwiindawo zeepaki, nakwiindawo ezixakekileyo zokunqumlana kweendawo. Ezi zixhobo zilula kodwa zintsonkothileyo zilinganisa ubungakanani bemvula enayo ngexesha elithile. Ukufundwa okuqokelelweyo kunceda iingcali zemozulu ukuba zenze uqikelelo, zazise abacwangcisi besixeko, kwaye zincede iinkonzo zongxamiseko.
Phakathi kwaba bagcini kukho inethiwekhi yeegeyiji zemvula ezenzekelayo eziqhutywa nguRhulumente waseQueensland. Zixhotyiswe ngobuchwepheshe obuphambili, ezi geyiji zithumela idatha yexesha langempela kwisiseko sedatha esiphakathi, zihlaziywa rhoqo ngemizuzu embalwa. Xa kufika isivuthuvuthu, le nkqubo ilumkisa ngokukhawuleza amagosa esixeko, iwavumela ukuba ajonge ubungakanani bemvula kwaye alandelele iindawo ezinokubakho zezikhukula.
“Xa kukho imvula enkulu, umzuzu ngamnye ubalulekile,” ucacisa uGqr. Sarah Finch, isazi ngemozulu kwiYunivesithi yaseQueensland. “Iigeyiji zethu zemvula zibonelela ngolwazi olubalulekileyo olusinceda siphendule ngokukhawuleza, siqinisekise ukhuseleko loluntu kunye nokukhusela iziseko zophuhliso.”
Usuku Kubomi Bokulinganisa Imvula
Ukuze siqonde impembelelo yezi gauge zemvula, masilandele uhambo lwe-“Gauge 17,” esinye sezikhululo zokulinganisa ezisebenzayo kwisixeko esikwiSouth Bank Parklands. Ngemini eqhelekileyo yasehlotyeni, iGauge 17 imi phezu kwendawo edumileyo yepikiniki, isakhelo sayo sesinyithi sikhazimla phantsi kwelanga.
Njengoko ubumnyama bugubungela isixeko, amathontsi okuqala emvula aqala ukuna. I-funnel ye-gauge iqokelela amanzi, iwaqondisa kwisilinda yokulinganisa. I-millimeter nganye yemvula eqokeleleneyo ifunyanwa yi-sensor erekhoda idatha ngoko nangoko. Kwimizuzu embalwa, olu lwazi luthunyelwa kwinkqubo yokujonga imozulu yeBhunga leSixeko saseBrisbane.
Xa isivuthuvuthu sisanda, iGauge 17 irekhoda isantya esimangalisayo seemilimitha ezingama-50 ngaphantsi kweyure. Olu lwazi lubangela izilumkiso kulo lonke isixeko—oorhulumente basekuhlaleni bahlanganisa izicwangciso zabo zolawulo lwezikhukula, becebisa abemi abakwiindawo ezinobungozi obukhulu ukuba balungiselele ukufuduka okunokwenzeka.
Ukuzibandakanya koLuntu
Impembelelo yeegeyiji zemvula idlulela ngaphaya kweziseko zophuhliso; ikwadlala indima ebalulekileyo ekubandakanyekeni koluntu nasekuqapheleni. IBhunga leSixeko saseBrisbane lihlala libamba iiworkshops kunye neenkqubo zemfundo ukufundisa abemi malunga neepateni zemvula kunye nemiphumo yazo. Abemi bendawo bayakhuthazwa ukuba bafikelele kwidatha yemvula ngexesha langempela nge-app kawonkewonke ebonelela ngeengxelo zemozulu ezineenkcukacha, kubandakanya idatha yembali malunga neemeko zemvula.
“Ukuqonda ukuba lina kangakanani na imvula kwisixeko sethu kusinceda sixabise imeko-bume esihlala kuyo,” utshilo utitshala woluntu uMark Henderson. “Abemi banokufunda ixesha lokonga amanzi kunye nendlela yokulungiselela imvula enkulu, babe ngabathathi-nxaxheba abakhutheleyo ekulawuleni izixhobo zethu esabelana ngazo.”
Ukumelana neMozulu kunye noBuchule
Njengoko utshintsho lwemozulu luzisa imingeni emitsha, iBrisbane iphambili kwiindlela ezintsha kunye neendlela zokuziqhelanisa. Isixeko sityala imali kwiindlela zokulinganisa imvula eziphambili ezinokukwazi ukulinganisa kungekuphela nje imvula kodwa kunye namanqanaba amanzi emvula kunye namanzi angaphantsi komhlaba. Le ndlela idibeneyo ye-hydrology iya kuvumela ukuqikelelwa okungcono kunye neziseko zophuhliso ezizinzileyo.
“Iigeyiji zemvula zisiqalo nje,” ucacisa uGqr. Finch. “Sisebenzela inkqubo yolawulo lwamanzi ebanzi echaphazela ithontsi ngalinye, siqinisekisa ukuba iBrisbane inokuphumelela nangona kukho ukungaqiniseki kwemozulu.”
Isiphelo
EBrisbane, apho imvula iluphawu lobomi, iigeyiji zemvula zenza okungaphezulu kokulinganisa imvula; zibonisa umoya wokuqina kunye nokuvelisa izinto ezintsha xa kujongwe imingeni yokusingqongileyo. Njengoko izivunguvungu zisina, ezi zixhobo zilula zikhusela ikamva lesixeko, zikhokelela ekuguqukeni kwaso kwi-oasis yasezidolophini ezinzileyo. Ngexesha elizayo amafu ehlangana phezu kwesi sixeko siphilayo, khumbula abagcini abazolileyo abasebenza nzima ukugcina abemi baso bekhuselekile kwaye benolwazi, ithontsi elinye ngexesha.
