Ukufika kweSiphepho i-Oriana kubangele zonke izexwayiso ku- Ibheseni lase-EbroIziphathimandla zamanzi zibikezela isenzakalo esikhulu sezikhukhula emifuleni eminingi ebhange elingakwesobunxele. Ngemva kwezinsuku eziningana zemvula eqhubekayo kanye nokuncibilika kweqhwa kancane kancane ezindaweni eziphansi, uhlelo lomfula lusondele kakhulu kumthamo walo ojwayelekile ngalesi sikhathi sonyaka.
I-Ebro River Basin Authority (CHE) imemezele ukuthi, kulo lonke uLwesihlanu noMgqibelo, kulindeleke imvula. ukwanda okuphawulekayo kokugeleza ikakhulukazi emifudlaneni egeleza ingene e-Ebro isuka ebhange layo elingakwesobunxele, isuka eNela iya eGállego. Nakuba isimo singaphansi kwalokho okubhekwa njengesikhukhula esivamile ezingxenyeni eziningi, ukuqapha okuseduze kuyagcinwa ngenxa yokuthi kungenzeka ukuthi kube nezikhukhula ezindaweni eziphansi nezisobala kakhulu.
Imifula ebhange elingakwesobunxele enezikhukhula eziphakeme kakhulu ezilindelwe
Ngokusho kolwazi olunikezwe yi-CHE, isiphepho sizohamba izimvula eziningi neziqhubekayo engxenyeni esenyakatho kakhulu yesitsha, okuzoholela ekukhukhuleni okukhulu emifuleni eminingana egeleza iye ogwini lwesobunxele lwe-Ebro. Imifula lapho kulindeleke khona ukukhukhula okukhulu yi- Nela, Jerea, Omecillo, Bayas, Ega, Arga kanye no-Irati Altozonke zizwela kakhulu ekunaweni okusheshayo nasekuncibilikeni.
Esigabeni sesibili sokuqina, kodwa futhi nangokwanda okukhulu, imifula I-Zadorra, i-Irati ephansi, i-Aragón, i-Gállego, i-Najerilla ne-JalónKulezi zimo, izikhukhula zihlala, ngokomthetho, ngaphakathi kwamanani ajwayelekile eziwombeni zesiphepho sasebusika, yize ukugeleza okuphezulu kwemvula ezingxenyeni ezithile kungenakugwenywa uma izimvula zidlula izibikezelo zokuqala.
I-CHE igcizelela ukuthi lezi zikhukhula ziza ngemuva izinsuku eziningana zemvula elula noma ephakathi kusatshalaliswe kulo lonke isigodi: ePyrenees, Pre-Pyrenees, kanye nase-Iberian System yasentshonalanga, kubhalwe phakathi kwamalitha ayi-10 nama-20 ngemitha yesikwele emahoreni angama-24 edlule, kanti kwezinye izindawo ezisele zesigodi, imvula eqongelelekile ayifinyelelanga amalitha ayi-10. Lesi sisekelo somswakama wenhlabathi, kanye nokulahlekelwa yizitshalo kanye nokubaluleka kwe- ukuvuselelwa kwamahlathi emifudlana yamanziLokhu kwenza kube lula ukwanda okusheshayo kokugeleza kwamanzi okuvela emjikelezweni omusha wemvula.
Ngaphezu kwalokho, ukuncibilika kweqhwa eliqongelelwe ku amazinga aphansi kakhulu Sekuvele kube nomthelela ezikhukhuleni ezivamile emifuleni efana ne-Aragón, i-Gállego, i-Alcanadre, i-Vero, i-Cinca, i-Ésera, i-Najerilla, ne-Jalón. Ukugeleza okuphezulu kwalesi siqephu esedlule kusanda kuqoshwa kuyo yonke le mifula, futhi izinga lamanzi liyancipha okwamanje, okunikeza ithuba ngaphambi kokufika kwentaba-mlilo ehlobene neSiphepho i-Oriana.
Imvula elindelekile kanye nokusabalala kwayo kulo lonke isigodi
Amamodeli ezulu asetshenziswa yi-Confederation abonisa ukuthi, phakathi kwalolu Lwesihlanu noMgqibelo, iSiphepho i-Oriana sizohamba phakathi kwamalitha angu-50 no-120 ngemitha yesikwele engxenyeni esenyakatho yesigodi, kusukela esiphethwini se-Ebro kuya esigodini saseGállego. Kukule ndawo kanye lapho kutholakala khona imifula eminingana engaseceleni kwesobunxele, okulindeleke ukuthi ibhekane nezikhukhula ezibaluleke kakhulu.
Endaweni yase-Iberia entshonalanga kanye nasePyrenees empumalanga, kusetshenziswa izibalo ze- Amalitha angu-30 kuya kwangu-50 ngemitha yesikweleNakuba ingxenye esele esenyakatho yesigodi kulindeleke ukuthi ithole amalitha emvula aphakathi kuka-10 no-20. Ingxenye eseningizimu yesigodi sase-Ebro, ngakolunye uhlangothi, izohlala ingathinteki kakhulu kulesi sigameko, njengoba imvula ingadluli amalitha ayi-10 ngemitha yesikwele kanye nomthelela omncane kakhulu maqondana nokugeleza kwemifula.
Esinye isici okufanele usicabangele ukuvela kwezinga leqhwaIsibikezelo sibonisa ukuthi, phakathi nosuku, izinga leqhwa lizokwehla kusukela kumamitha ayi-1.500 liye cishe kumamitha ayi-1.000 ngaphezu kolwandle, futhi lingase lehle kancane. Lokhu kwehla kusho ukuthi okunye kwemvula ewe njengeqhwa ezinsukwini ezedlule manje kuzona njengemvula, okusheshisa ukugeleza kwamanzi emifuleni futhi kwandise amathuba okukhukhula, esikhundleni sokuqongelela kancane kancane njengeqhwa.
I-CHE icacisa ukuthi, ngisho nalesi simo semvula enamandla enyakatho, kwezinye izindawo Akulindelekile ukuthi umkhawulo wamalitha angu-50 ngemitha yesikwele udlule.ikakhulukazi engxenyeni ephezulu ye-Aragonese yesigodi sase-Ebro. Naphezu kwalokhu, isimo sisabhekwa njengesibucayi ngoba sidlula isikhathi sangaphambilini semvula eqhubekayo kanye nenhlabathi egcwele kakhulu.
Uma kubhekwa konke, ukusabalala kwemvula kanye nokuziphatha kokuwa kweqhwa kubeka imifula ogwini lwesobunxele esimweni sokuthi impendulo esheshayo yamanzi, ngezikhukhula ezivamile ezisakazekile futhi ngezinye izikhathi ezibalulekile kulezo ziteshi ezinomthamo omncane wokukhipha amanzi noma ezinezingxenye ezincane, ezivalekile.
Indima yamadamu okugcina amanzi kanye nokukhishwa kwamanzi okulawulwayo
I-Ebro River Basin Authority iqokomisa indima ebalulekile edlalwa yi- amachibi amakhulu esitsheni Kulesi siqephu. Ngenxa yamandla ayo okugcina, ingxenye enkulu yezikhukhula iyamuncwa noma ilawulwa, okunciphisa kakhulu umthelela wezikhukhula ezingezansi komfula.
Ukuze kulawulwe lesi simo, izindawo eziningi zokugcina amanzi zikhethe ukwenza ukuchitheka okulawulwayo Inhloso ukushelela ukugeleza okuphezulu kanye nokulungisa amazinga edamu ngesikhathi esisodwa. Izibonelo eziphawulekayo zifaka phakathi i-Yesa, enamamitha angama-cubic angu-400 ngomzuzwana akhishwayo, kanye ne-Mansilla kanye ne-Barasona, enamamitha angama-cubic angu-100 kanye namamitha angama-cubic angu-150 ngomzuzwana, ngokulandelana. Le misebenzi ivumela ukulungiswa kwamandla engeziwe ngokulindela imvula elindelekile.
Ikholi umphumela wokulamina Indima yamadamu ibaluleke kakhulu eMfuleni i-Ebro ezansi kwamachibi amakhulu, njengoba enciphisa izikhukhula futhi ebambezela ukuphakama kwawo. I-Ebro River Basin Authority (CHE) igcizelela ukuthi lo msebenzi wokulawula uzoba semqoka ekugcineni, ngangokunokwenzeka, ukugeleza kwamanzi ngaphakathi kwemingcele evamile kanye nokunciphisa ingozi ezindaweni zasemadolobheni eziseduze nomfula.
Noma kunjalo, kubalulekile ukukhumbula ukuthi, naphezu kwemizamo yokulawula, ezigamekweni zeziphepho ezinamandla njenge-Oriana kuhlale kukhona ithuba lokuthi ukwanda kwendawo kokugelezaLokhu kuyiqiniso ikakhulukazi emifudlaneni emincane noma ezindaweni lapho iziphepho noma imvula enamandla kakhulu kunalokho okwakubikezelwe ekuqaleni. Ngakho-ke, kunconywa ukuthi kuqashwe njalo ezindaweni ezivame ukuba nezinkinga.
Kunoma ikuphi, igunya lesifunda somfula ligcizelela ukuthi le misebenzi yokukhipha amanzi yenziwe ngendlela ehleliwe neqondisiwe, kanye ukuxhumanisa phakathi kwezinsizakalo zokusebenza kwamadamu kanye nezinhlelo zokubikezelaLokhu kuvumela izinqumo ukuthi zilungiswe cishe ngesikhathi sangempela ukuze zivumelane nokuvela kwesiphepho kanye namazinga okugeleza ezindaweni ezahlukene zokulawula.
Amanani okugeleza abikezelwe eMfuleni i-Ebro kanye nemifudlana yawo eyinhloko
Ngokuphathelene nomzila oyinhloko, i-Ebro River Basin Authority (CHE) ilindele ukuthi i-Ebro izofinyelela amanani asondele kakhulu kuzamcolo ojwayelekile phakathi kweMiranda de Ebro kanye nendawo ehlangana noMfula i-Aragón. Kusukela kuleso sigaba kuya emlonyeni, ukugeleza kuzoba ngaphansi komkhawulo wezikhukhula ezivamile, yize ukwanda okwengeziwe okuphansi kunalokho osekubhaliwe ezinsukwini ezedlule akunakuphikwa.
Phakathi kokugeleza okubaluleke kakhulu okulawulwa yi-ejensi kukhona izindawo eziningana zokulawula ezisatshalaliswa kulo lonke isigodi: e-Ebro eMiranda, kulinganiselwa phakathi 400 futhi 600 cubic metres ngomzuzwananjengoba kulindeleke ukuthi kube nokuphakama okukhulu ekuseni ngeSonto. EMfuleni i-Ega, eduze kwase-Estella, kulindeleke ukuthi kube namazinga okugeleza aphakathi kwama-cubic metres ayi-150 nama-250 ngomzuzwana ngoMgqibelo ntambama.
Emfuleni i-Arga, njengoba udlula e-Echauri, amamodeli akhomba uhla lwezinhlobo Ama-cubic metres angu-600 kuya kwangu-800 ngomzuzwana NgoMgqibelo ntambama, ngesikhathi eMfuleni i-Irati, esiteshini sokulinganisa i-Liédena, kulindeleke ukugeleza okungu-200 kuya ku-400 cubic metres ngomzuzwana, nangoMgqibelo ntambama. Lezi zigeleza ezisogwini lwesobunxele zizodlala indima ebalulekile ekwakheni ukugeleza okuphelele koMfula i-Ebro ezindaweni zawo eziphansi.
Ezansi komfula, eMfuleni i-Ebro eLogroño, amazinga okugeleza aphakathi kuka- 800 futhi 1.000 cubic metres ngomzuzwana NgeSonto ekuseni, naseCastejón, kulinganiselwa ukuthi umfula ungageleza phakathi kwamamitha ayi-1.500 no-1.800 ngomzuzwana ngeSonto ntambama. Lezi zibalo zibonisa ukugeleza okuhlangene kwemifula emikhulu osebeni lwesobunxele esimweni semvula enkulu kanye nokuncibilika kweqhwa kancane.
Ezindaweni ezahlukene eceleni koMfula i-Ebro ongenhla, omasipala bendawo kanye nezinsizakalo zokuvikela umphakathi baqapha ngokuseduze ukugeleza kwemifula. Ezindaweni lapho umfula ugeleza khona isondela emikhawulweni yokuchichimaAmadivayisi athile okuqapha asebenze, kugxilwe kakhulu ezindaweni ezisengozini ngokwesiko, njengemifula ethile yasemadolobheni kanye nomhlaba wezolimo emathafeni aphansi.
Izincomo kanye nokuqapha izakhamuzi
I-Ebro River Basin Authority incoma ukuthi umphakathi kanye nabasebenzisi bemithombo yamanzi yomphakathi baqaphele kakhulu ezinsukwini ezizayo, ikakhulukazi ezindaweni ezizungeze imifula yase-Ebro River Basin Authority. ibhange lesobunxele le-Ebro lapho kulindeleke khona izikhukhula ezinkulu kakhulu. Kunconywa kakhulu ukuthi kugwenywe ukufinyelela ezindaweni ezivame ukuba nezikhukhula, amazibuko, amabhange emifula, kanye nogu olungazinzile ngesikhathi somcimbi.
Ukuze uthole ulwazi olusha, i-CHE ikhuthaza abasebenzisi ukuthi bahlole njalo iwebhusayithi ye- I-SAIH Ebro (Uhlelo Lolwazi Lwe-Hydrological Oluzenzakalelayo)lapho idatha yemvula, kanye nokubonwa nokubikezela amazinga amanzi kanye nokugeleza eziteshini zokulinganisa kulo lonke isigodi, kungabuyekezwa cishe ngesikhathi sangempela. Ukuvela kwemithombo yamanzi emachibini amakhulu nakho kuyaboniswa.
Iziphathimandla zisikhumbuza ukuthi izibikezelo zamanzi zivuselelwa njalo ngokusekelwe ku- ukuvela kwangempela kwemvula nokugeleza kwemifulaNgakho-ke, amazinga okugeleza abonisiwe angalungiswa emahoreni azayo. Ngakho-ke kubalulekile ukulandela izimemezelo ezisemthethweni futhi ungathembeli ezilinganisweni zangaphambilini uma isimo sezulu sishintsha.
Okwamanje, izinsizakalo zokuvikela umphakathi zikamasipala nezesifunda zigcina imisebenzi yazo isebenza. izinqubo zokuqapha izikhukhulaKufanele kuqashelwe kakhulu izingxenye lapho izinga elijwayelekile lezikhukhula lingase lidlule khona. Ukuxhumana phakathi kwalezi zinsizakalo kanye ne-River Basin Authority kubalulekile ukuze kusabele ngokushesha kunoma yikuphi ukuwohloka kwesimo okungenzeka.
Ukuhlanganiswa kwezimvula ezinkulu, ukuncibilika kweqhwa okuyingxenye, kanye namachibi asebenza ngokugcwele kubeka imifula osebeni lwesobunxele lwe-Ebro ibhekene nesigameko sezikhukhula, yize ezimweni eziningi zizohlala zisesimweni esijwayelekile samanzi, Kusiphoqa ukuthi singavumeli ukuqapha kwethuImpendulo yesigodi emahoreni azayo izoba yinto ebalulekile ekuqinisekiseni ukuthi izibikezelo ezilandela kakhulu zinembile noma ukuthi kudingeka yini izinyathelo ezengeziwe zokuvimbela.
