Abstract
Major flood events occurred in the Arda River region in the last decades with great economic, social and environmental effects. A specific software package has been developed for the simulation of the flood runoff and routing process of the transboundary Arda River basin. The software package is taking into account the existence of the three cascade Bulgarian reservoirs aiming to flood protection and power optimization. Inflow estimations for duration of five days ahead and initial water levels at the three reservoirs are imported at the beginning of the simulation. The management tool includes all the alternative operation modes of hydropower plants, water released from spillways, and river and reservoir flow characteristics in order to optimize the total system (power generation and flooding costs) during the flood event. The developed software is also an efficient tool for the establishment of a flood warning system.
Highlights
The Arda is a 290-kilometre long river in southeastern Europe and crosses two countries, Bulgaria and Greece
Despite the fact that the developed software has been developed for a specific river basin, it can be implemented in any basin containing cascade artificial reservoirs and the results could be utilized by stakeholders for flood management by integrated reservoir operation
A new computer software program has been developed for the simulation of the rainfall-runoff and flood routing processes of the transboundary Arda River basin
Summary
The Arda is a 290-kilometre long river in southeastern Europe and crosses two countries, Bulgaria and Greece. Flood warning systems are more and more being used to make ready at-risk communities for the purpose of minimizing flood affects [3] In this context, Bulgaria and Greece cooperated within the “European cross-border cooperation program Greece-Bulgaria 2007-2013” in a common project with title “Flood warning system establishment in Arda River basin for minimizing the risk in the cross border area—ARDAFORECAST”, in order to face together the existence of flooding events in the area. In case of Arda River, the catchment area is shared between two countries, Bulgaria, the upstream country and Greece the downstream country, the discharges of Arda adversely affect Turkey as well In such a case the transboundary flood management is a long process and typically undergoes different stages. Despite the fact that the developed software has been developed for a specific river basin, it can be implemented in any basin containing cascade artificial reservoirs and the results could be utilized by stakeholders for flood management by integrated reservoir operation
