Ati: “Ubu ni cyo gihe cyo gutangira kwitegura ingaruka zishobora guteza umwuzure ku kiyaga cya Mendenhall n'umugezi.”
Ikibaya cy’ubwiyahuzi cyatangiye gutembera hejuru y’urugomero rw’ibarafu kandi abantu bamanuka bava muri Mendenhall Glacier bagomba kwitegura guhangana n’umwuzure, ariko nta kimenyetso cyagaragaye guhera mu gitondo cyo kuri uyu wa gatanu mu gitondo cyo kuwa gatanu harekurwa amazi y’umwuzure ukabije, nk'uko byatangajwe n’ubuyobozi bw’ikigo cy’igihugu gishinzwe iteganyagihe Juneau.
Ikibaya kimaze iminsi gisohoka buri mwaka kizwi ku izina rya jökulhlaups kuva mu mwaka wa 2011, cyuzuye kandi “igabanuka ry’amazi rijyanye n’amazi arenga urugomero rwa barafu ryamenyekanye mu gitondo cyo kuri uyu wa kane,” nk'uko byatangajwe na NWS Juneau yasohotse ku isaha ya saa kumi nimwe zijoro ku wa kane ku rubuga rw’ikurikiranabikorwa ry’ubwiyahuzi. Iri tangazo rivuga ko byatwaye iminsi itandatu uhereye igihe ikibase cyuzuye kugeza igihe irekurwa ry’amazi ryabaye umwaka ushize.
Iri tangazo rigira riti: “Nibimara kumenyekana ibimenyetso by’amazi yo munsi y’ubutaka, hazatangwa umuburo w’umwuzure.”
Amakuru mashya yasohotse saa cyenda zo kuwa gatanu yavuze "imiterere ntabwo yahindutse" kumunsi ushize.
Andrew Park, inzobere mu bumenyi bw'ikirere kuri sitasiyo iherereye hafi y’urubura, mu kiganiro twagiranye mu gitondo cyo kuri uyu wa kane, isuka ry’amazi “ntibisobanura ko kurekurwa bibaye ubu.”
Ati: "Ubu ni bwo butumwa bw'ingenzi - ko tuzi ko tubizi kandi duhagaze ku yandi makuru".
Icyakora, ku bantu bo muri ako gace “ubu ni cyo gihe cyo gutangira kwitegura ingaruka zishobora guteza umwuzure,” nk'uko byatangajwe na NWS Juneau.
Kuva ku wa kane mu gitondo, amazi y’umugezi wa Mendenhall yari metero 6.43, ugereranije na metero enye mu ntangiriro z’umwaka ushize. Ariko Park yavuze ko ikintu cy'ingenzi mu buremere bw'umwuzure uwo ari wo wose muri uyu mwaka ari uburyo amazi yatemba vuba mu kibaya igihe urugomero rwa barafu ruvunitse.
Ati: "Niba ufite akavuyo gato ntabwo rwose ari ikibazo". “Ariko kura ayo mazi icyarimwe ufite ibibazo bikomeye.”
Ubushakashatsi bw’Amerika muri Jewoloji bwashyizeho ibikoresho bishya byo gukurikirana ku kiraro cya Mendenhall ku muhanda wa Back Loop mu gitondo cyo kuri uyu wa kane kugira ngo bifashe kuyobora imyiteguro yo gusohora ikibaya cy’ubwiyahuzi. Umwaka ushize ubwo isohoka ry’amazi ryabaye ku ya 5 Kanama, USGS yishingikirije gusa ku kiyaga cya Mendenhall.
Randy Host, inzobere mu bijyanye n’amazi hamwe na USGS, yavuze ko ibipimo by’umuvuduko bizatuma hakurikiranwa andi mazi y’umwuzure unyuze mu ruzi.
Ati: "Bizakora stage, icyo twita uburebure bwa gage, nkuburyo uruzi ruri hejuru". Ati: “Hanyuma kandi bizakora umuvuduko wo hejuru. Bizapima uburyo amazi yihuta hejuru.”
Benshi mu ruzi rwa Mendenhall ubu rwuzuyemo urutare kugira ngo barinde inyubako nyuma y’umwuzure w’umwaka ushize wangije cyane inkombe z’umugezi. Umwuzure washenye igice cyangwa burundu amazu atatu hamwe nandi mazu arenga mirongo itatu yangiritse kuburyo butandukanye.
Umwaka ushize, Amanda Hatch, inzu ye yuzuyemo amazi ya santimetero umunani mu mwanya w’inyamanswa, yavuze ko ivugurura rikomeye ryo kurushaho kurinda urugo rw’umuryango we ryarangiye.
Ati: "Ntabwo duhangayikishijwe cyane kuko twazamuye inzu metero enye". Ati: "Ariko dufite imodoka y'amashanyarazi, niba rero umwuzure tuzazamura imodoka hejuru y'umuhanda tujya kwa mugenzi w'inshuti. Ariko turiteguye."
Umwanya wo gukurura inzu nawo wongerewe ingufu kugira ngo urinde umwuzure, Hatch yavuze. Yavuze ko ubwishingizi butigeze bwangiza ibyangiritse mu mwaka ushize, ariko gutabara no gutera inkunga ibishakishwa binyuze mu ishyirahamwe ry’ubucuruzi buciriritse ryafashije mu gusana no kuzamura bishoboka.
Hatch yavuze ko ibirenze ibyo, nta byinshi byo gukora usibye gukurikirana ibibera.
Ati: "Ntawubwira uko bizagenda, si byo?" "Birashobora kuba hejuru. Birashobora kuba bike. Birashobora kugenda gahoro. Tugomba gutegereza kureba. Nishimiye ko urutonde rwacu rwakozwe ku buryo tutagomba rwose kubitekerezaho."
Marty McKeown, inzu ye yangiritse cyane ku buryo hasize icyuho munsi y’icyumba cyo kuraramo, yavuze ko akomeje gusana inzu ndetse na patio yogejwe - kandi usibye inguzanyo ya SBA itabonye ubutabazi yari yizeye mu mujyi cyangwa mu zindi nzego za Leta. Yavuze ko afite “impungenge zo hejuru” ku bijyanye n'ibihe biriho, ariko ko adahagarika umutima kuko akurikirana uko ikibaya gihagaze.
Ati: "Tuzareba uruzi kandi dufate ingamba nibiba ngombwa". Ati: “Ntabwo ngiye gutangira kwimuka mu rugo rwanjye. Tuzabona igihe niba hari ikintu kibaye.”
Mu kwezi gushize, muri Kamenaau hashyizweho amateka mashya y’imvura, raporo ibanza yerekana santimetero 12,21 z’imvura ku kibuga cy’indege mpuzamahanga cya Juneau ugereranije n’ubushyuhe bwo hejuru bwa santimetero 10.4 muri 2015. Hari imvura yagereranijwe ku minsi yose uretse iminsi ibiri y’ukwezi, harimo na santimetero 0,77 zapimwe ku wa gatatu.
Iteganyagihe mu ntangiriro z'icyumweru gitaha risaba gukuraho ikirere n'uburebure bugera muri 70.
Umuyobozi wungirije w’umujyi mu Mujyi na Borough ya Juneau, Robert Barr, yavuze ko imvura nyinshi yaguye muri Juneau ireba kuko iyo uruzi ruri hejuru, usanga umwanya muto wo kurekura amazi yuzura uruzi. Yavuze ko CBJ yakira raporo y'ibihe bya buri munsi muri NWSJ.
Ati: "Baduha ibitekerezo byabo byiza ku bijyanye n'uko jökulhlaup yaba imeze mu nzego zitandukanye zo kurekura niba iramutse isohotse mu gihe cya raporo". "Buri gicamunsi rero tubona ibyo. Kandi mubyukuri ibyo bitubwira nukumenya niba jökulhlaup yarekuwe nonaha, kuri 20% kugeza kuri 60% yubunini bwose bwikibaya cyubwiyahuzi, dore uko jökulhlaup yaba imeze. Niba irekuwe kuri 100% yubunini bwikibaya cyubwiyahuzi - umwaka ushize wasohotse kuri 96% - dore uko jokulhlaup izaba imeze."
Barr yavuze ko ikibase kidakunda kurekurwa 100%. Umwaka ushize nicyo gitabo kinini ikibase cyasohoye icyarimwe. Ariko nta buryo bwo kuvuga uburyo amazi azasohoka vuba.
