From time to time a concept enters geomorphology that is transformative in the way we think about and understand how landscapes function. One such concept that may fit this description is that of Magnitude and Frequency. In this session we seek to explore the question whether the concept of connectivity can be afforded the same status. Certainly the concept has found its way into a significant number of publications. Starting in the 1980s there has been a more-or-less exponential growth in the annual number of publications employing the concept. But have these publications been transformative or, as has been suggested, no more than old wine in new bottles? We invite contributions from across the discipline that span case studies of geomorphological research employing connectivity thinking through to broader methodological or conceptual discussions that critique the contributions connectivity has made to geomorphology.
