Résumé partiel
Because of the natural flow of the water from upstream to downstream, from one region to another, and from one boundary to another, and at the same time the growing number of user such as domestic, agriculture, energy, transport, industry, tourism, spiritual and cultural values, environment, and so many other users, there are growing possibilities of intra-national and international conflicts between these users. Allocation of this fugitive, life giving, limited and multidimensional matter between these competing users will increase these possibilities or may decrease. A good, sound and proper way of allocation of water to get the satisfaction of all users within the same river basin will definitely affect positively. One of the factors which is seen as a solution, through policies and practices made by governments, to the allocation problems is the development of large infrastructure on the river basins. This may also have an effect to the relations between upstream and downstream or between the users. Large reservoirs or multi-purpose dams are one type of these infrastructures. Dams may have positive impact and at the mean while negative impact as well on the upstream and downstream flow and users.The aim of this research was to study the water availability and reservoir development and operation in Hari Rod River Basin, Afghanistan. To see the historical water supply and demand and to observe the shortages of supply in time and in percentage in future increasing demand due to population growth and limited amount of water. To see the impact of two dams (Salma and Kabgan) which are going to be built on this river by Afghanistan government to allocate water to different users in the region.The data for this study has been collected from two main sources ; the global and the local. Hari Rod River Basin is a data scarce region and this was a big challenge during the data collection and data analysis. Two main user has been identified in the basin ; the Agriculture as the largest user and the domestic as the second largest user. WAFLEX model has been used for this study due to simplicity, user friendliness, transparency and less data requestness of the model. This model was set-up for fifteen years period with historical data of 1962-1976 to simulate the future water allocation. Two aforementioned dams are also included in the future simulation to explore possible management options for the operation of these dams to increase the satisfaction level of users and to decrease the possible impact on the downstream flows. The finding of this research shows that there is possibility to use the global data sets along with local data sets for water resources assessment and allocation. And the result of the simulation shows that the annual surface water allocation in this river basin is 3251 M m3/a. The current situation 3% is abstracted by domestic water use and 76% is abstracted by agriculture water use. there was an expectation that the demand will exceed the supply in the future due to development and population growth, but still in 2027 abstraction and demand will only increase by 2% indomestic and 01% for agriculture, but there will be shortages if the same allocation strategies (Traditional way) is going on in the field. In the base case scenario the annual water demand was 1865Mm3/a, but increases in current scenario as 2257Mm3/a and development scenarios as 3705Mm3/a for both domestic and agriculture users.
