SYSTEMS ANALYSIS OF TALEGHAN MULTIPURPOSE PROJECT, IRAN

Abstract

This dissertation focuses on the use of Optimization and Simulation Models on Taleghan River Basin in Iran which can help to conceptualize the Taleghan River Problems and are used to find optimal solutions with respect to different purposes. The Taleghan River Basin is located in the Taleghan Valley approximately 135 kilometers northwest of Tehran. The future reservoir at Sangban Damsite and the ground water reservoir of Ghazvin Plain which is connected by a 9 km. tunnel, can be responsible for irrigation of Ghazvin plain and Tehran domestic demands as well as industrial demands, plus generating as much as water energy as possible by means of proper hydroplants. Any decision making on the more suitable design should depend on the relationship between the amount of irrigation releases as well as domestic water demands versus the Taleghan dam heights for different alternatives, obviously, based on simulation model which has been developed, exact detail have been computed. In the present study SYSTEMS ANALYSIS OF TALEGHAN MULTIPURPOSE PROJECT,IRAN ,Project planning has been carried out by modelling the systems by linear programming to explore the different possible alternatives. All runs were made for a specific year only (70% dependability). Finally, simulation technique has been adopted for selecting the best feasible solution among the various alternatives. Due to the high regulation potential, operation of the systems has been simulated in monthly steps for 39 years. With this model and computed capability optimal water use has been analysed with respect to size of surface reservoir, size of diversion tunnel, capacity of ground water reservoir and operation schedule to determine best combinations to meet programme objectives.
