Hydro-Technologies in Greece from Prehistory to Modern Times: A Review of Water Management, Sustainability, and Resilience

Greece exhibits a continuous and exceptionally well-documented tradition of water management extending from prehistoric times to the modern era. This review critically examines the evolution of Greek hydro-technologies within their historical, environmental, and socio-political contexts, highlighting their enduring relevance to contemporary water resource management. Beginning with the advanced hydraulic systems of the Minoan civilization, the study traces the development, transformation, decline, and rediscovery of water management practices across successive periods, including the Mycenaean, Classical, Hellenistic, Roman, Byzantine, Venetian, Ottoman, and modern Greek eras. The analysis is based on a synthesis of archeological evidence, historical sources, and technical studies from approximately 200 documented sites throughout Greece. Particular emphasis is placed on water supply, drainage, sanitation, irrigation, and governance systems, as well as on periods during which hydraulic knowledge was partially lost and later reintroduced or adapted. Representative case studies illustrate the spatial and technological diversity of Greek hydro-technological solutions, ranging from monumental aqueducts and dams to decentralized cisterns, wells, and communal irrigation systems. The review demonstrates that Greek hydro-technologies consistently integrated technical innovation with environmental adaptation, social organization, and institutional regulation. This diachronic synthesis provides transferable lessons for modern water governance, infrastructure resilience, and climate adaptation, offering a conceptual framework for addressing contemporary challenges related to water scarcity, climate variability, and sustainable water management in Mediterranean and semi-arid regions.
