In recent years, water has emerged as one of the principal determinants of power, security, and geopolitical competition at both regional and international levels. Given the growing challenges facing water resources and the increasing complexity of hydropolitical relations in West Asia, the adoption of non-structural technologies and innovative management approaches in water governance and resource management has become an essential necessity. Integrating modern water governance approaches with geopolitical, economic, security, and technological capacities has the potential to enhance the regional standing of states. Accordingly, the present study aims to examine the role of the Hybrid Hydro-Hegemony Framework in strengthening Iran’s geopolitical power in West Asia. This research adopts a descriptive–analytical approach. The required data were collected through a researcher-developed questionnaire based on a five-point Likert scale, comprising 30 items administered to a sample of 500 experts and specialists. Data were analyzed using descriptive statistical methods by examining the level of respondents’ agreement with each dimension of the proposed framework. The findings indicate that the highest levels of agreement were associated with the dimensions of smart water governance and technological innovation, regional geopolitical power, and strategic security and deterrence. The results further reveal that, although water diplomacy and transboundary cooperation possess considerable potential for enhancing Iran’s regional influence, realizing this potential requires strengthening institutional mechanisms, fostering mutual trust, and promoting sustainable cooperation with neighboring countries.
