Modeling Integrated Water Resources Management by WEAP, Case of Watersheds Mabtouh (North-Western Algeria)

Water management remains a difficult and complex task due to the multiplicity of user-users, which necessitates the use of decision-making tools, especially in regions with high water stress. This paper attempts to test a model to develop an integrated water resource management scenario, applied to a watershed (Mabtouh River in northwestern Algeria), hosting hydro-agricultural infrastructure (dam, irrigated perimeter), an industrial zone as well as urban agglomerations. The methodology adopted consists in applying the Water Assessment and Planning System (WEAP) model based on a reference year dataset (2014), which attempts to consider the allocation of water to the Horizon 2050, according to two scenarios involving climatic constraint. The results lead to the implementation of scenarios contributing to reducing conflicts of use between consumers.
