Ushintsho lwesimo sezulu sendawo lungase luthinte iColorado River Onerous
Njengengxenye yalokhu kulandelana kwalokhu okusha okusha, Njalo ngoLwesihlanu (NgoMgqibelo ku-Phrinta) Singabhekana nesihloko esisha sha esihlobene nokuphepha kwamanzi ku-Iron and Washington Counties. Qinisekisa futhi njalo ngeviki ukuthola izibuyekezo kumaphoyinti wamanzi aqhubekayo, izingxoxo nababonisana nabo, kanye nokuhlolwa kwendlela esizoqinisekisa ngayo ikusasa elikhudlwana lamanzi emiphakathini ekhuphukayo eningizimu-ntshonalanga.
Ukubopha amakhono okwenziwa kabusha okukhulayo kwekhompyutha, okusha okusha funda ihlele ukusakaza ukusakaza ngaphakathi komfula weColorado River Basin ngenhlamvu, ukusondeza okwengeziwe-kusilinganiso kulokho obekutholakala ngaphambili. Nokuthi bakutholile ngeke kube imininingwane emihle ye 40 abantu abayizigidi ezibika njengamanzi eColorado River.
Maqondana 85 I-P.C ye-Colorado River Amanzi isuka eqhweni leqhwa kanye nemvula ngaphakathi kwendawo yasekhanda lomfula eWest Slope of Coloun Mountains. Ukusuka lapho, Iyaqhubeka yaphansi komfula ukuqeda ukoma kwamadolobha afana neLas Vegas, Phoenix futhi, Uma I-Lake Powell Pipeline kwakhiwa, Mpumalanga. Ukugcidalwanayisa lase-GOORGE. Kodwa-ke ngaphambili kunangaphambili., Amanzi ambalwa awo avulwa amahlathi aphezulu ahlala e-alpine avergree.

Ososayensi bathola lokho, Ngokuncipha kwesilinganiso segridi yemephu esetshenziselwa ukwazi futhi ukufingqa amandla amanzi ngaphakathi kwe-Colorado's Area, Babekwazi ukubamba okwengeziwe kwe-Nuance yezemvelo yokuthi i-panorama ezintabeni ithonya kanjani inani lamanzi ekugcineni ligcina ligeleza phansi. Ukutholwa kwabo, Ishicilelwe online ngasekupheleni kukaJulayi ngaphakathi kwejenali Izinhlamvu zokuhlaziya imvelo, Ncoma ukuthi amafashini angaphambilini asebenzisa amagridi wemephu yama-coarser kungenzeka ukuthi aveze isikhundla samahlathi ahlala eluhlaza emithambekeni ye-alpine ngokweqile futhi abukele phansi ukuthi angaphendula kanjani ekushintsheni kwesimo sezulu sendawo.
"Imfashini okwamanje esetshenziselwa ukubikezela amanzi wesikhathi esizayo ihlinzeka nge-Southwest U.S. ngokuyinhloko ngokusekelwe kulawa ama-grids amakhulu awenza lula izintaba,"Okukhulunywe ngaye ULauren Foster, Isazi se-hydrologist eneqembu lokusongelwa kwemvelo eColorado, INeptune nenkampani, kanye nomqambi wokuhola ephepheni lokuhlaziya. "Kodwa-ke kukhona iqembu elithile lokuphakama indawo ihlathi lingabulwa kakhulu emazingeni okushisa akhuphuka, futhi lelo bhendi lizoqashwa ngalezi zinhlu ezinkulu. "
Kakhulu nje njengoba abantu bathambekele ekujuleni okungeziwe futhi kufanele baphuze amanzi angeziwe ezinsukwini zesikhathi esishisayo zasehlobo, amabhasi angeziwe alahlekelwa ngamanzi emoyeni ngokusebenzisa i-evapotranspireware futhi kufanele athathe amanzi angeziwe ukusuka phansi ukuze akwenzele lokho kulahleka lapho amazinga okushisa avuka. Lokho kuyiqiniso kakhulu emahlathini aphakeme aphezulu angalinganiswa ezimweni ezibandayo.
Yini egxile lapha kugxile kulolu sosayensi ngokusondeza ezisekelweni zehlathi ukuthi, Ngoba isimo sezulu sendawo esifudumele kanye nezihlahla zifuna ukucwilisa amanzi angeziwe ukuze alwe nokulahleka kokuhwamuka kokuhwamuka, Ubungako bamanzi abasele ekusakazweni kwe-downriver lizokwehla 4 P.C okukhulu kunalokho okubaliwe amafashini angaphambili.
"Lokho 4 I-P.C yokuhlukanisa ingahle ibonakale iyinani elincane,"Uphawulwe lukhulisa. "Kodwa-ke kufanele ukhiphe lokho kuwo wonke ama-rockies, Kungamanzi amakhulu amanzi omfula iColorado. Kungaba yinto eyodwa uma amafashini akhona ebelokhu ebeka phansi amanzi ethu esikhathi esizayo anikela ngenxa yalokho nakanjani uzobe usulungele ikusasa ngamanzi angeziwe. Noma kunjalo iqiniso abalahla ngokweqile, Kungasho ukuthi sinamanzi amancane kakhulu kunalokho esilindele ngaphakathi kokulandelayo 50 iminyaka. "

Lo mthelela ohlala njalo ngeke ukhawulelwe ku-Colorado River Basin. Ukuthola okufanayo kungahlobene, kukhuthazwe, kunoma yimuphi umfula otholwe ezintabeni zezintaba. Nge-Western U.S. kulindeleke ukuthi kukhuthazelele ukufudumala nokumisa imiphumela engezansi kwezimo zesimo sezulu esizayo, Lokhu kuthola ukuthi ama-bush akukaze abhekwe ngokuphelele kumafashini angaphambilini angabikezela ukushoda kwamanzi njengoba izilimo zihlehla umoya oguqukayo ngokuncintisana ngesabelo sakhe.
Kodwa-ke kufanele ngabe ulindele ukuthi lokhu kungaba yi-lining yesiliva eqinisweni lokuthi lesi sikhathi sasehlobo sibone amathani amahektare amahlathi asentshonalanga akhuphuka ngentuthu, Ake sithi futhi. Ngamahlathi aphuma emthunzini emithambekeni yentaba, Sluggish Snowmelt, nomhlabathi wezimpande endaweni, Imifula yethu ingaba yifomu elibi kakhulu.
"Okufanele sikwenze ukuqala okubalwa yilolo flux enkulu yokuhwamuka okuthi sonke esiyaziyo ukuthi kwenzeka ngenxa yalokho senza ucwaningo olunzulu, Siyayibona,"Uphawulwe lukhulisa. "Kufanele siqale ukubalwa kwalowo mphumela emanzini ethu uma sibikezela ukuhlinzeka ngezinto zesimo sezulu sendawo."
Okwengeziwe:Thepha Amanzi: Ukoma kwethu inyama yenkomo kungenzeka kulimaze izinhlanzi, Ucwaningo olusha luthola
Ngokudabukisayo, Brian Richter, umongameli we Amanzi Asenziwe, Iqembu lokuqeqesha amanzi emhlabeni, kushiwo ukuthi ubona isayensi efana nalokhu ngokujwayelekile ayinakwa. Ufunda ucwaningo lokukhuthaza futhi wabizwa ngokuthi "isayensi ezwakalayo ngemininingwane emibi kakhulu." Ucabanga ukuthi ucwaningo luhlinzeka ngokuthanda okugcwele kokuthi kungani ukufudumala kwesimo sezulu sendawo kunombono ongemuhle ezinhlelweni zamanzi omdabu. Kodwa-ke anethemba lokuthi kuzokhuthaza ushintsho ekuhlelweni kwamanzi kamasipala.
"Angicabangi ukuthi abaphathi bamanzi kanye nabenzi bezinqumo zezombusazwe ngaphakathi komgodi weColorado River Basin bakhokha ukucatshangelwa okwanele kulokho isayensi yesimo sezulu esisitshela yona,"Richter okukhulunywe ngaye. "Ngizwa imiphumela yalesi simo sezulu sendawo samanzi esihlinzeka ngaphakathi koMfula iColorado inzima kakhulu kunalokho abakucabangayo. Kuze kuqale ukuthatha lolu lwazi ngokuhlolisisa futhi kwamukele ngokuqagela kwabo okuhlinzeka futhi kudinga ukuthi amanzi kungekudala, Ngeke basinike isithombe esiphelele nesinokwethenjelwa. "
Kunjalo, kukhulume uRichter, Ngokuya ngathi ngifuna ukuthi isayensi yamanzi yamanzi ibekwe emandleni afuna amanzi.
