Webiga Mereb (Af Talyaani: fiume Mareb), oo sidoo kale loo yaqaan Webiga Gash (Af Carabi: القاش), waa wabi ka soo qulqula bartamaha Eritrea. Muhiimaddiisa ugu weyn waa inay qayb ka mid ah xuduudka u dhaxaysa Eritrea iyo Itoobiya, inta u dhaxaysa barta ay Mai Ambassa ka gasho wabiga ee 14°53.6′N 37°54.8′E / 14.8933°N 37.9133°E ilaa isugu geynta Balasa iyo Mereb ee 14°38′N 39°1.3′E / 14.633°N 39.0217°E.[1]
Koorsada
[wax ka badal | wax ka badal xogta]Sida uu sheegayo Statistical Abstract of Ethiopia for 1967/68, Webiga Mereb waa 440 kilometres (270 mi) dhererkiisu. Wasaaradda Khayraadka Biyaha ee Itoobiya waxay ku warramaysaa in aagga uu biyaha ka ururiyo ee Itoobiya uu yahay 5,700 square kilometres (2,200 sq mi), iyadoo sanadkii uu qaado 0.26 bilyan oo mitir kuyuubik ah.[2] Ishaarado kale ayaa ka hadlaya in aagga uu biyaha ka ururiyo uu yahay 21,000 square kilometres (8,100 sq mi) ilaa 44,000 square kilometres (17,000 sq mi) guud ahaan, iyo qulqul dhan 21.6 cubic metres per second (760 cu ft/s) celcelis ahaan sanadkii, iyo 870 cubic metres per second (31,000 cu ft/s) xilliga ugu sarreeya.[3] Isha udugu waxay ka kacaan koonfur-galbeed ee Asmara ee bartamaha Eritrea. Wuxuu u qulqulaa koonfurta, isagoo xuduud la leh Itoobiya, ka dibna wuxuu u qulqulaa galbeedka iyada oo loo sii marayo galbeedka Eritrea si uu u gaaro bannaanka Suudaan ee u dhow Kassala. Si ka duwan webiyada Setit ama Takazze, kuwaas oo ka qulqula Itoobiya oo sidoo kale samaysta xuduud dabiici ah oo la leh Eritrea, biyaha Mereb inta badan ma gaaraan Webiga Niil[4] laakiin waxay ku baaba'aan ciidda bannaanka bariga Suudaan, iyagoo samaynaya delta gudaha ah.
Mereb waa mid qallalan inta badan sanadka, laakiin sida Takazze waxay la kulantaa fatahaad kedis ah xilliga roobka; kaliya xeebta bidix ee koorsada sare ee Mereb ayaa ku taal dhulka Itoobiya. Wabi hoosaadyadiisa ugu waaweyn waa Obel oo ku taal xeebta midig (ee Eritrea) iyo Sarana, Balasa, Mai Shawesh, iyo Webiyada 'Engweya oo ku yaal bidixda (ee Itoobiya).
Taariikh
[wax ka badal | wax ka badal xogta]Mereb wuxuu muhiim u ahaa taariikh ahaan xuduud ahaan laba gobol oo si gooni ah loo maamuli jiray oo ku yaal aagga: dhulka Bahr negash (Af-Tigrinya "boqortooyada badda", oo sidoo kale loo yaqaan Medri Bahri ama "dhulka/by badda") ilaa waqooyiga wabiga, iyo Tigray ilaa koonfurta. Dhulalka hoos yimaada Bahr negash waxay ku fidayeen ilaa waqooyiga xeebta Badda Cas, iyo ilaa koonfurta (iyo galbeedka) ilaa Shire[5] waxaana caasimaddu ay ku taallay Debarwa ee Eritrea casriga ah, qiyaastii 20 miles (30 km) koonfurta Asmara.
Duurjoogta
[wax ka badal | wax ka badal xogta]Dhul-qoyanka Eritrea ee wabiga ayaa ahaa goobtii 2001 lagu arkay raxan maroodiyaal ah, oo ahayd markii ugu horreysay ee noocan oo kale ah oo laga arko Eritrea tan iyo 1955.[6]
