- Idilesi: Bark Dar, Ethiopia
Enye yamanzi amaninzi apheleleyo kunye ahloniphekileyo kwilizwekazi laseAfrika kunye nehlabathi lonke - uMlambo iNayile - livela kumabini amabini: i-White and Blue Nile, ize iqhubekele eLwandle lweMeditera. Inkolelo yaseYiputa yaseYiputa yamzukisa iNayile iminyaka emininzi izayo. Kodwa konke ukunyuka komlambo omkhulu kunembali yakhe kwaye kubaluleke kakhulu kumhlaba apho uhamba khona.
IJografi yeBlue Nile
Umlambo olungileyo weNayile (iNayile) - uMlambo we-Blue Nile - unokuhlala ubude bee-1,783 km kwaye uvela kwiiNtshonalanga zaseAtiopia (i-Abyssinian) kwiiNtaba zeChokeh nakwamanzi aseLake Tana. I-800 km ye-Blue Nile idlula kwimida ye- Ethiopia , ngoko iya kudibanisa neNayile eNayile kwintsimi yeSizwe saseSudan. I-echibi elingaphantsi kwe-1830 m ngaphezu kwinqanaba lolwandle lilawulwa yidama lendawo, apho kwakhiwa khona isitishi samandla kagesi.
Ngaphakathi kwemida ye-Ethiopia, i-Blue Nile ngabemi basekuhlaleni ibizwa ngokuba ngumlambo wase-Abbay. Ngethuba lemihla yethu, ngekhulu lama-21, i-rightbutton yeNayile, njengaphambili, ithathwa njengesitya esingcwele, esivela kwiParadesi (Eden). Ngeentsuku zemikhosi karhulumente kunye nenkolo kunye nemikhosi, i-Blue Nile ithola iminikelo evela kubahlali beendawo zokuhlala unxweme ngendlela yesonka kunye nezinye iimveliso zokutya.
I-Blue Nile inezinyathelo zayo - uRahad kunye neDinder. Ukutya okuphambili komlambo wonke ngumvula.
Inkcazelo yeBlue Nile
Ilungelo elifanelekileyo leNayile ukusuka kumthombo walo ngokukhawuleza ufumana amandla kwaye ufike ku-580 km ngumlambo ongasemikhumbi. Iikhilomitha zokuqala ezingama-500 zesitya sokungena kwi-canyon yamandulo, ubunzulu bayo buhluka ukusuka kwi-900 ukuya kwi-1200 m. Ububanzi bomgwaqo wamanzi kwi-canyon ngu-100-200 m. Amanzi asezantsi e-Blue Nile asetyenziswa ngokutsha kwezolimo, ukunkcenkceshela kwekotoni kunye nokubonelelwa kwamanzi kubemi.
Ngexesha lezimvula ezinkulu, i-Blue Nile ingaphezu kwe-60% ye-runoff, kwaye ngokwezinye iingxelo-malunga ne-75% yeNayile yonke. Ukuhamba kwamanzi okulinganiselwa kuma-2350 cubic metres. m ngomzuzwana. Kodwa ngexesha elomileyo umlambo awunzulu. Ngo-2011, amagosa aseTopiya aqalisa ukuxhasa inkxaso-mboleko enkulu-iDamente enkulu yaseTopiya "Ukuvuselela". Le projekthi kufuneka ifakwe ama-hydroun radial-axial ngamanqanaba angama-5250 MW.
Yintoni enomdla ngeBlue Blue?
Ukushiya i-Ethiopia, i-Blue Nile i-cross yeNayile, abemi bayo bayayibiza ngendlela yabo: umlambo iBahr al-Azraq. Nangona kunjalo, inguqulelo yesiNgesi yaseArabhu yiyo "ulwandle oluhlaza". Kodwa ngolwimi lwesi-Amharic, oluthethwa ngabaninzi baseTopiya, i-Blue Nile ibhekiselwa kuphela "njengomlambo omnyama".
Kwiidolophini zedolophu yase-Er-Rosérez, abaninzi abakhenkethi benza iifoto ezikhethiweyo ezingasayikulibaleka kuMlambo iBlue Nile: enye yezona ziqithi ezinkulu kwiSudan zakhiwe apha. Esinye isityalo se-hydropower sifakwe emlanjeni kwisixeko saseSennar. Ukuqhubela phambili emlanjeni sele sele kufuphi nomzi-dolophu waseKhayrtoum kunye neNayile edumileyo ibonakalayo: nantsi ingongoma ye-confluence yamacandelo amabini: i-Blue Nile ne-White.
Ndingafika njani?
Imvelaphi yeBlue Nile inokufumaneka njengenxalenye yokuhamba kwiLake Tana okanye ngemoto ngokuzimela. Ukuqhutyelwa kweNayile eNkulu kuthatha isiqalo sayo kufuphi nomzi waseBar Dar , apho kusenokwenzeka ukuba ufike kwindawo yeTana ngasetekini nakwezinyawo.
Abavakhenkethi abanolwazi bancomela ukuba banakekele izicathulo ezintle kunye neempahla ezifanelekileyo.
