Somalia is periodically affected by various forms of natural and manmade hazards. Floods are notably one of the most devastating natural hazards in the country, causing tremendous loss of lives and extensive damage to agriculture, vegetation, human, wild life and local economies. Juba-Shabelle River Basin is the source of the two most significant rivers (Jubba and Shabelle) in the country that provide sufficient water for crop production, livestock and for domestic use (Figure 1). It is widely believed that the alluvial plains of the two rivers to be the breadbasket of Somalia as they have considerable potential for irrigation development. However, floods are a common phenomenon in the riverine areas of the Juba and Shabelle River basin during the two main rainy seasons of Somalia Gu (April to June) and Deyr (October to December). The low-lying areas along the Juba and Shabelle Rivers are usually experienced flooding of various magnitudes. This is caused or amplified by both weather and human related factors. The natural one is due to quantity and frequency of precipitations experienced by the Ethiopian side of the Juba and Shabelle River Basin is far more exceeding than the one occurs in Somalia.
