  • Summary

    The concept of connectivity appeared in several disciplines in the 1950s and 1960s, but did not enter geomorphology until the 1980s. The concept has led to profound insights into the behaviour of systems, and has had significant applications in management. Connectivity may be defined as a structured set of relationships between spatially and/or temporally distinct entities), or as the degree to which a system facilitates (or impedes) the movement of matter and energy through itself. The former definition focuses on the structure of the system, and the latter on the functioning of it. The two definitions give rise to the separate concepts of structural and functional connectivity. A fundamental difference between structural and functional connectivity lies in the fact that, whereas the former can be relatively easily measured, and a variety of tools exists to do so, the latter tends to be inferred from system behaviour, so that measurement is somewhat indirect. Notwithstanding the compelling arguments in favour of studying connectivity, the ability to apply the ideas of connectivity science in any discipline requires a number of challenges to be addressed.

  • Summary

    In this chapter, the history and development of the concept of connectivity in geomorphology is presented. It further provides an overview of connectivity terminology, the underlying concepts and identifies the benefits of connectivity thinking for geomorphological research and applications. We further pursue the question of whether connectivity can be considered as key concept in geomorphology and address general key challenges in using connectivity to understand complex geomorphic systems.

  • This edited work provides the first comprehensive account of how connectivity concepts and methods are applied in geomorphology. Addressing both qualitative and quantitative aspects, this volume demonstrates how the powerful conceptual framework of connectivity can be used to effectively describe material transfer between geomorphic system components. The book begins by introducing the key elements of connectivity science, drawing from a broad range of disciplines. The latest research on connectivity is then presented for each major process domain, including hillslopes, rivers and glaciers. Methods of quantification and measurement are described, providing an overview of methodologies and indices that can be used to assess connectivity as a property of soils and landscapes, and approaches for modelling connectivity are reviewed. The book concludes with an examination of applications of connectivity thinking in environmental management. Accessible and self-contained, this text is a key resource for practitioners, researchers and graduate students in geomorphology.
