The 8th International Conference on Geomorphology of the International Association of Geomorphologists (IAG/AIG) took place in Paris at the Cité des Sciences de La Villette from August 27 to 31, 2013. The main topic of this 8th Conference was "Geomorphology and Sustainability". Organized by the Groupe Français de Géomorphologie (GFG) and open to all scientists and practitioners, this Conference included 26 scientific sessions, 5 key-note lectures and one Workshop devoted to Young Geomorphologists. YOUNG GEOMORPHOLOGISTS SESSION Convenors: Etienne COSSART, Johnny DOUVINET & Stuart LANE This session welcomed young scientists (PhD students, post-doctorates) who were interested in discussing new approaches and methods in geomorphology (spatial analysis, mathematical modelling, conceptual and quantitative approaches and links between them). Presentations could focus on any component of the discipline and related earth sciences (hydrology, Quaternary geology, soil sciences, etc.), and be either fundamental or applied. Preliminary results and discussions of fieldwork and methodological strategies (observation, data acquisition before modelling) were appropriate, as well as methodological developments, such as geomorphic mapping through GIS. Equally, numerical simulation approaches such as those linked to complexity theory (agent-based modelling, Cellular Automata) or physically-based methods for specific process representations have been welcomed. The participants of this session have been invited to participate to the intensive course for young geomorphologists held at the end of the conference (from September 1st to 3rd).
