As part of the long-standing common project between the Martens Centre and the KAS Skopje Office on “Cross-Border Cooperation: Water Management between Greece and North Macedonia”, this publication comes as a result of the collaboration between professors and scientists from the Faculty of Mechanical Engineering at the Ss. Cyril and Methodius University in Skopje, North Macedonia, and the School of Civil Engineering at the Aristotle University in Thessaloniki, Greece.

The transboundary surface water bodies of Vardar/Axios River, Dojran/Doirani Lake and Prespa Lake have undoubtful importance at national and regional levels fostering economic prosperity and development, social integrity and environmental protection. The management of these waters at the basin scale is a step forward for achieving closer cross-border cooperation and for promoting sustainable development. The outputs of this book demonstrate the current situation, as well as the progress that has been conducted in the management of the transboundary waters of the two countries.
