The problem with you Sahal....is that you mix up your desires with facts.
J/Land receives more rain, has more fertile land, and carries more water than the Shabelle river/region.

The Shabelle River Basin

The Shabelle river basin in the Horn of Africa is a transboundary river basin shared between Ethiopia and Somalia. Running a distance of about 1500 km, the Shabelle River (meaning Leopard/Tiger) rises in the Ethiopian Highlands and passes through an arid land in eastern region of Ethiopia [5] known as Ogaden Plateau cutting then wide valleys in southern Somalia. After crossing into Somalia, it approaches the coast near Mogadishu. Annual rainfall at the source exceeds 1000 mm. The river does not normally enter the Indian Ocean, but disappears into a depression area, where it is finally lost in the sand in southern Somalia near the town of Jilib, not far from the Jubba river. Only with exceptionally heavy rains in Ethiopia does the Shabelle River break through to join the Jubba and thus succeed in reaching the ocean.

With an average annual rainfall of 455 mm and much higher potential evaporation, mean annual runoff of the Shabelle River at the Somali town of Beledweyne is 2 384 million m3 (FAO, 1989). According to the reports from Ethiopia, annual river runoff is 3 160 million m3. Over 90% of the runoff is however generated by catchments within Ethiopia (ibid.). As the river crosses the existing international border between Ethiopia and Somalia, the Somali City of Beledweyne in the Hiiraan region is the most important point where the river flow and its water quality could be observed inside Somalia. The river has a high saline content even during high flows. The river basin has recurrent droughts and devastating floods generated by heavy rains in the Ethiopian highlands which often cause flooding in Somalia with huge damages. In 2006, the river has been affected by the worst flooding in many years and many provinces were badly affected by the floods.

The Jubba River Basin

Like the Shabelle, the Jubba River originates from the Ethiopian Highlands, where three large tributaries, the Genale, the Dawa and the Weyib, meet near the border with Somalia to form what is known in Somalia the Jubba River. The rainfall at the source reaches 1500 mm/y, dramatically decreasing southwards and the mean is 550 mm. The basin falls mainly in the arid and semi-arid zone and is generally drought prone with erratic rainfall. In Somali, the Jubba basin region receives most rains in Somalia and the river gives its name to two Somali administrative regions. The Somali town of Luuq is the most important point to observe the runoff of the Jubba River as it crosses the border. The Jubba, which enters the Indian Ocean at the portcity of Kismayo, has a total length of 1 100 km, 550 km of which is in Somalia. The mean annual runoff at the town of Luuq is 6 400 million m3; Ethiopia again contributes over 90% (FAO, 1989). Kenya occupies larger part of the basin and section of the Dawa river forms part of the border with Ethiopia, but as there are no known tributaries originating there contributing to the main river channel with significant flow of surface runoff; it does not normally contribute to the Jubba, and has no access to the main river thus any significant interests for the water resources in the river.

The Jubba basin region is primarily savanna and is the richest part of Somalia due to its fertility as well as biodiversity. The Jubba has flood seasons in both spring and autumn. The river expeinced 1997 its worst flood in living history. The Jubba valley is part of the nation's chief agricultural region, and the river is extensively used for irrigation.

The Shabelle and Jubba rivers are the only rivers in Somalia, while they are the second and third largest of the twelve rivers of Ethiopia. The Shabelle is larger in size and longer in distance than the Juba, but these did not lead the Shabelle to be larger in terms of runoff due to climatic and geological conditions. The two rivers are now international and it is historically attributed to the Colonial Administration, who arbitrarily drew the political borders between Somalia and Ethiopia during late 19th and mid 20th centuries (Drysdale, 1964). The impact of colonial division on Somalia’s water resources is significant, but will be understood more in the future. As Somalia's most water resources exist in these rivers, runoff contributions by catchments in Somalia are normally minimal. The effects of this factor will be analysed later in the paper.
