Study of the Assignment Scheme of Water Resources in the Tafna Watershed

Abstract

The problem of water is likely to arise sharply for Algeria and especially its western region in a more or less near future. However, the Tafna basin from which are drawn the main conventional and unconventional water resources for the wilaya of Tlemcen and neighboring wilayas. Thus, the preservation of these water resources is one of the fundamental issues of our time. The increase in removals and discards due to population growth and economic development is increasingly threatening the quantity and quality of this vital resource. In Algeria, the climatic hazards observed, combined with a strong demography, contributed to an unavoidable shortage of mobilizable resources.The policies adopted over the last twenty years, in terms of dam construction and desalination of seawater, remain insufficient. A more rational vision needs to be developed regarding the management of these resources. . It is in this sense that this work aims to study the allocation of water resources in the Tafna watershed as part of an integrated management, while calculating the hydraulic balances resource needs for the different uses of water and for different horizons. Assignment scenarios will be proposed for short, medium- and long-term horizons by comparing the supply to the needs of the various water users in the Tafna watershed. Stakeholders such as water users and managers will be involved to manage water in an integrated and sustainable way and meet current demand and prospects for better supply.
