Information - GM2.4 Geomorphic response to Holocene environmental change: Simplicity or complexity?
Environmental changes have triggered a variety of responses in geomorphic systems at different spatial and temporal scales. In general, system response is dependent on the magnitude of change, and assumptions about this relationship are commonly made in establishing direct causal links between the geomorphic record and the history of environmental change. But even small changes in relatively simple geomorphic systems can lead to rather complex responses. Depending on internal system dynamics, a response may be buffered and/or delayed, and result in rather complex causal relationships between environmental change and the geomorphic record. Understanding the underlying complexity in cause and effect relationships is a necessary prerequisite for successful reconstruction of Holocene environmental changes from the geomorphic record. Alternatively, it can be argued that, as with many physical systems, this complexity in landscapes is underlain by rather simple laws governing system behaviour.
We enthusiastically invite contributions that explore relationships between Holocene environmental change and geomorphic response at different spatial scales and at different degrees of complexity. We welcome contributions with a variety of techniques and from both ends of the spectrum: empirical field-based studies as well as analogue and/or numerical modelling experiments.
