Optimum Management And Operation Of Karun And Dez Water Resources Systems And Hydropower – Hydro Thermal Plants

The Karun and Dez River System are coming under increasing pressure from demands for hydro-electric power generation and domestic, industrial, agricultural, environmental and navigation water demands, whilst at the same time maintaining an adequate flow in the river systems, both in terms of quantity and quality is required.

Objectives:

The aim is optimum use of water resources via development of a dynamic management and operation system of existing water and power resources in their present condition and several future development scenarios in the “Karun” and “Dez” river basins.  With respect to the following guidelines within the framework of comprehensive water schemes which should address the following points:

>  Estimation of water resources potential and demands at present conditions and several stages of future development.

>  Optimization of rivers, ponds and reservoir systems, management and operation with respect to their priorities, resources allocation, re-appraisal of the results of the allocations.

>  prepare quantitative and qualitative mathematical models as well as setting reservoir operation policies and a dynamic rule curve for various purposes of water resources operation and allocation of water resources (dispatching management) for various purposes like agriculture, domestic and industrial water supply, navigation or transfer of water to other basins in view of social and other constraints.

>  Coordinating for combined energy generation between hydro and thermal plants in order to gain an optimum generation combination, subject to constraints on the availability of water and other parameters.

>  Optimization of operational policies for several water demands with respect to limitation of water and taking into consideration of future development of hydro as well as thermal plants.

>  Prepare a quantitative and qualitative surface water balance for the existing and future time horizons.

>  Optimization of flood control in reservoirs.  Conservation an optimum volume of flood control in the reservoir for maximizing its active storage with respect to integrated reservoirs operations and in the rivers path as well as presenting suitable solutions for addressing a flood control system to reduce inherent dangers.

>  The possibility to increase the land area under cultivation by implementing optimized deficiency policy in facing and meeting water demands.

>  Recognizing all existing polluting factors point and non point source pollutions which affect on surface and subsurface water quality in existing and future conditions, together with the development of physical as well as management methods for reducing polluting loads entering reservoirs and rivers, and reorganizing specific environmental conditions ruling over the plan and the effects of the plan on the surrounding environment.  Also presenting management and refining plans and the required fundamental institutional frame for optimum utilization of development and environment strategies (policies).

>  Exploring the possibility of using the river for navigation from different aspects and presenting the required executive approaches to the issue.

>  Develop and formulate an integrated optimization model applied to plan for the most efficient use of the river system such as power generation, Agricultural, industrial and domestic demands in existing and future conditions

>  Water resource management for flood control and river navigation

>  Improve water quality management system

>  Develop technical specification of a new water quality monitoring system

>  Improve staff's technical knowledge and transfer of technology
