Development of Decision Support System for Optimization of Dams’ Management on Complex River Systems

The thesis presents a complex approach for modelling of a complex reservoir systems for water drainage management. The model has been built over a segment of a river with a certain parameters of water inflow, water outflow, required power production and max possible flood occurrence. Then the segments may be replicated with specific parameters to simulate whole system of the river. The model has been optimized in order to obtain the water drainage operation policy with regards of current and expected water volumes in the reservoirs ratio, required power production revenue, and minimal flood occurrence. Model has been verified on a walk-through basis on Valle D'Aosta river system and Volga-Kama river system. Flood propagation has been modelled in HEC-RAS software, while post-processing and impact analysis were performed in QGIS 3.0. The results show that proposed management approach allows to decrease the impact caused by inundation at Volga-Kama river basin by two times compared to the one implemented by the operator management approach. This result is achieved due to mitigation of the flood in highly populated areas and allowing additional water discharge among water management facilities in the areas with low population. Thus developed approach provides optimal water drainage for minimum flood occurrence and desired power production revenue.
