A study was conducted on water allocation modeling of Awash River Basin, Ethiopia, using MODSIM, a river basin management decision support system (DSS) designed as a computer-aided tool for developing improved basin wide planning. This study was conducted to analyze the water balance of the Awash Basin under different levels of irrigation development and also determine the water allocation in the Upper, Middle and Lower Valleys in the basin. Awash Basin includes Koka Dam and 2 dams under completion : Kesem and Tendaho Reservoirs. Analysis of flow records within the basin was done for 1963–2003. Simulation was conducted on 4 scenarios. Consumptive and non-consumptive uses were considered in allocation modeling. The results of MODSIM model depict that there will be incremental release from Koka Dam from 2.8% to 5.7% in years 2018 and 2038, respectively. Expansion of the irrigation schemes in the Upper Valley is sustainable till 2018. Present irrigation can be sustainable up to year 2028 without having additional storage
