Juqraafi
[wax ka badal | wax ka badal xogta]Marin
[wax ka badal | wax ka badal xogta]Geba waxay ka kacdaa aagga ugu waqooyi ee Guinea ee buuraha Fouta Djallon, waxay martaa koonfurta Senegal, waxayna gaartaa Badweynta Atlaantik ee Guinea-Bissau. Wuxuu leeyahay dherer dhan 550 kilometres (340 mi).[2]
Waa webi inta badan ku yaal dhul hoose, oo leh qulqul sare inta lagu jiro xilliga roobka (laga bilaabo Juun ilaa Oktoobar). Aagagga ku xeeran qaybaha hoose ee webiga waa dhul-badeed lagu hareereeyay savanna iyo kayn, oo leh cufnaanta dadka oo ku tiirsan beerashada nolosha.[3]:162
Afka Geba waa af-webi ay hirarku saameeyaan ballaaran oo lala wadaago Webiga Corubal.[4] Heerka hirarku wuxuu gaari karaa 7 metres (23 ft) gudaha af-webiga (oo sidoo kale loo yaqaan Geba Channel).[5]
Laamihiisa waxaa ka mid ah webiyada Anambe, Gambiel, iyo Campossa (ama Colufe). Webiga Colufe wuxuu ku biiraa Geba meel u dhow Bafatá. Geba waxay wadaagtaa af-webi ballaaran oo ay la socoto Webiga Corubal (kaas oo ay kaga biirto meel u dhow Xime). Bissau, caasimadda Guinea-Bissau waxay ku taal xeebta waqooyi ee af-webigan. Af-webigu wuu sii ballaaraa marka webigu ku qulqulo Atlantic-ga hareeraha jasiiradaha Bijagós.[6][7][8]
Bulaacada
[wax ka badal | wax ka badal xogta]Bulaacada Geba waxay dabooshaa qiyaastii 12,000 square kilometres (4,600 sq mi). 65% bulaacada waxay ku taal Guinea-Bissau, 34% Senegal, inta hartayna waa geeska waqooyi ee Guinea.
Geba, oo ay weheliso Webiga Corubal, waxay ka daadisaa Bafatá Plateau. Waxay sidoo kale ka daadisaa Gabú Plain, iyada oo ay la socoto Webiga Farim (oo sidoo kale loo yaqaan Webiga Cacheu), iyo laamahooda.[9]
Dhaqaalaha
[wax ka badal | wax ka badal xogta]Geba waxay muddo dheer ahayd marin ganacsi oo muhiim ah oo ku xiran gudaha; waxaa heli kara maraakiib 2,000-tan ah qiyaastii 140 kilometres (87 mi) gudaha, iyo maraakiibta qabyo-tirka leh xitaa in ka badan.
Magaalada Geba, oo ku taal qaybta la mari karo ee webiga, waxay u adeegtay sidii saldhig ganacsi oo weyn. Waxay ku xirtay marinno ganacsi oo ay lahaayeen Soninke, Mandé, Kaabu, iyo Biafada. Geba waxay ku lug lahayd ganacsiga addoonta ee Atlantic. Kola nuts, biraha, iyo fool-maroodiga ayaa sidoo kale halkaas lagu ganacsan jiray.[10]
