Abstract: The 11th international conference on fluvial sedimentology was held in University of Calgary, Canada, from 17 to 21 July 2017. As a pageant of international fluvial sedimentology, once four years, scholars who came from North America, European, Australia and Asia attended the conference. A series of academic topics were presented and discussed in different technical programs. More reports and sessions focus the following fields:1)River dynamics and change, including linking modern river processes to the ancient record, beyond overbank-complex dynamics of channel-floodplain systems, perspectives on river dynamics and change, and reconstructing river channel migration:Next generation forensics for plane evolution patterns, and turbulence, grain interactions, and sedimentation in alluvial and bedrock rivers. 2)Rivers on the edge, including where the river meets the sea:morphodynamics and sedimentology in systems with combined fluvial and tidal currents, transitions in flow, morphology and stratigraphy along river-fed margins, and dryland fluvial and alluvial systems, fluvial-aeolian interaction, and pre-vegetation, non-vegetated, or ‘normal’ rivers, processes and deposits. 3)Fluvial stratigraphy and subsurface resources, from source to sink sedimentological and stratigraphic analysis, braided or meandering are fluvial facies models useful, and types of rivers preserved in the stratigraphic record. 4)Managing fluvial landscapes, including the climate changing, mud and vegetation of floodplain influence on the discharge and models of fluvial, and the evolution of alluvial island and meandering channel, and the role of biostabilized sediments in fluvial environments. Based on the data of 11th International Conference on fluvial sedimentology, we considered the quantitative research of evolution progress of fluvial, the physical simulation and numerical simulation of fluvial sedimentology, reconstructing the point bar and calculate the date of facies model, and using the detrital zircons as a next dating tool in source to sink sedimentological and stratigraphic analysis, in which some will still be important research and development fields of international fluvial sedimentology.
