Water is one of the strategic raw materials needed not only for the very existence of people but also for agriculture and industry, or as an infrastructure or energy source. The aim of this thesis is to determine what variables and concepts of the Water Resources Management constitute for the Jordan River basin, to be approached as maintained by a hegemonic power. Selected comparison study deals specifically with Israel and Jordan and explores the role played by both of these states on the regional hegemony. The work is based on a realist’s power understanding of a regional hegemon, together with the implementation of the concepts that constitute for Hydro-Hegemon. Subsequently, the definition of the power as such, followed by the realist vision of regional hegemony and finalized with the Hydro-Hegemony concepts through small n-sample analysis, is applied. In conclusion, evaluation of the results of the theoretical approaches on the specific cases of Israel and Jordan, are presented
