Résumé partiel
Reservoirs are primarily built to alter the naturaltemporal and spatial distribution of water resources, which also changes the ecology of water dependent ecosystems. They play an essential role in the economic development around the world by providing water for hydropower generation, flood mitigation, irrigation, fishing activities and providing water for domestic uses. Operation of the reservoir is usually accomplished using specific operation policies or rules, which give guidelines for making water release decision under various conditions. The primary focus of this study was to assess an optimal reservoir operational strategy for Tarbela Dam that enhances irrigation and energy demand reliability. The current reservoir operation strategy was evaluated by semi-structural interviews, questionnaire survey with the end users during the field visit and by using water allocation model WEAP. For future allocations reservoir operations of newly proposed storages including Diamer Basha Dam and Dasu Hydropower project were also evaluated in thisresearch using WEAP. This research also helps in creating an understanding of optimal strategies with and without new reservoirs regarding the balance between water releases for irrigation and energy. The results of the study indicate that current reservoir operational strategy is quite optimal. Modification / change in current reservoir operational strategy of Tarbela Dam (priority of hydropower generation instead of meeting irrigation demand) will increase hydropower reliability from 2 % to 62 % (comparison with base model). However, it will result in 32 % reduction in irrigation demand reliability hence increasing the unmet demands in the irrigation system from 10 BCM/year to 42 BCM/year. Four different scenarios were developed after addition of two proposed reservoirs upstream of Tarbela Dam (Diamer Basha & Dasu) in the WEAP model.
