  Hormozgan Province, located in the south of Iran, faces several challenges
regarding water resources management. The first one is the discharge of a
massive volume of water to the Persian Gulf because of the concentration of the
annual rainfalls in a short period of time and the narrow distance between the
headwater and the coast. The second one is the unbalanced development of
economic sectors in comparison with distribution of fresh water resources.
Finally, long-term drought is also common in this area. The construction of a
carry-over dam (Esteghlal Dam) and several conveyance pipelines and withdrawing
of the surface water and groundwater resources were considered as the solution
to deal with those challenges. During recent drought, severe overdraft and
inefficient use of recourses confirmed the fact that all done before are not
enough. During this period, there was a tendency to store water in reservoir in
order to meet the demand of the urban sector. Therefore, the agricultural
demand was the first victim of water allocation policy. It caused over
exploitation of the groundwater resources (to meet the agricultural demand) and
considerable losses (evaporation and leakage) from the reservoir. All of the
above-mentioned problems confirm the necessity of the development of a
conjunctive use policy. In this paper, all demand related to the Esteghlal Dam
and the Minab Aquifer (Bandarabbas City and agriculture in the Minab Plain)
were considered as the case study. The main objective was to find the best
applicable conjunctive policy which as well guarantees the conservation of the
Minab Aquifer. Alternative water allocation policies have been developed based
on the present capacities and the experience of local operating staff.
