Original Paper


The process of securing water supply is one of the biggest problems in the world. Along with the ever-increasing demand for water for different users, water resource management agencies face many challenges, some of which may be an obstacle to achieving sustainability and guaranteeing water for the various sectors of water supply. To face this dilemma, integrated water resources management is the best approach. The region of Tipaza is facing this problem. Through this work the WEAP model is applied to assess and analyze the current and projected balance of water resource management taking into account the different policies and operational factors that can affect the demand up to the year 2050. The results of the simulation showed that a deficit of 18.936Mm3 will be registered in the year 2042. For the years 2043 and 2044, the demand will be of the same order as the supply. For the period 2045 to 2050 a deficit of (3.44Mm3 to 85.48 Mm3) will be recorded in the case of scenario RCP4.5. On the other hand, in the case of the pessimistic scenario RCP8.5, the deficit will start from the year 2025 and will continue until the horizon of the year 2050 with 130.95 Mm3.
