Background: The current climate change has increased water scarcity at watershed scale. Interests’ conflicts between riparian communities are becoming commonplace. Objective: To solve such problem in Mpioka basin, in the Democratic Republic of Congo, this study aims to set up an integrated water resources management (IWRM) tool in this basin. Methods: Four types of data were used in this study. Hydrological and hydro-meteorological data allowed water balance evaluation and available water resources calculation in terms of discharge. Sociodemographic data were used to estimate current and future water and electricity demand. Land use mapping led to cultured area calculation and crops classification. Economic data and hydraulic parameters of the Mpioka dam facilitated its calibration in the model. Finally, a water allocation model was developed using Mike Hydro and Nile Basin Decision Support System (NB-SS) softwares, while crops water needs were evaluated using CROPWAT software. This model included three development scenarios and one baseline scenario. Results: At environmental level, Mpioka dam (SC1) will lead to a regulation of downstream discharge with a flow rate ranging 2.5 to 4m3/s irrespective to below 1m3/s, in the dry season, to 25m3/s, during the rainy season, in current situation. In addition of socio-economic standards and policies, nearly 150 jobs created, the hydropower plant will generate 76GWh/a. Thus, 50% of the basin population could gain access to electricity. Conclusion: The whole stakeholders’ opinion groups agreed unanimously that the Mpioka dam construction (SC1) seems to be the first development priority in the Mpioka basin. Then, could follow, gradually: the construction of Pilgrimage Center (medium term) and the development of Nkamba agro-industrial irrigation scheme (long term). In view of the present study results strengthening, it would be desirable to carry more investigations out in order to complete the performed multicriteria analysis (MCA) by a costs and benefits one (BCA). The latter will allow to assess the contributions of each development scenario in terms of economic gain for best decision making.
