The present volume originates in the Graduate Archaeology at Oxford Conference, an annual event for graduate students and early career researchers to present their archaeological research. The 2023 conference, titled "H2Oxford: Water Flowing Through Archaeology", focussed on water's role in human interactions and its archaeological remnants. This volume explores the pivotal role of water in human history and its archaeological significance, bringing together diverse contributions that reflect the breadth of contemporary research. Covering a wide range of topics -including maritime archaeology, water management, material culture, landscape archaeology, and theoretical approaches- it examines water's influence on human interactions and its material traces across geographical and chronological contexts.
