“…Recently, there has been a realisation that the assumption of a succession of vegetation or soil types is rather more complicated than this simple conceptual model and interactions of soil formation, vegetation development and geomorphological activity have become a new focus (Eichel et al, 2013(Eichel et al, , 2015Temme and Lange, 2014;d'Amico et al, 2014;Temme et al, 2016).…”

“…Then non-metric multidimensional scaling can be used to facilitate comparisons between groups, cf. Eichel et al (2013Eichel et al ( , 2015. (Table 2), but a SfM-derived DEM can be compared DEM from another source, such as ALS (e.g.…”

“…Heckmann et al, 2016a and references therein). This recent increase in attention is due to a growing realisation that these landscapes exhibit a range of properties that make them a highly relevant subject of study: First, they are unique natural laboratories where the successional development of soil and vegetation can be investigated; recent studies emphasise the interaction of soil and vegetation development and geomorphological dynamics (Temme and Lange, 2014;Eichel et al, 2013Eichel et al, , 2015Temme et al, 2016). Second, due to the high rates of geomorphological activity, they form an ideal location for the application of mapping and measurement methods to document and quantify changes, and to test models,…”

Short-term geomorphological evolution of proglacial systems

Proglacial systems are amongst the most rapidly changing landscapes on Earth, as glacier mass loss, permafrost degradation and more episodes of intense rainfall progress with climate change. This review addresses the urgent need to quantitatively define proglacial systems not only in terms of spatial extent but also in terms of functional processes. It firstly provides a critical appraisal of prevailing conceptual models of proglacial systems, and uses this to justify compiling data on rates of landform change in terms of planform, horizontal motion, elevation changes and sediment budgets. These data permit us to produce novel summary conceptual diagrams that consider proglacial landscape evolution in terms of a balance of longitudinal and lateral water and sediment fluxes. Throughout, we give examples of newly emerging datasets and data processing methods because these have the potential to assist with the issues of: (i) a lack of knowledge of proglacial systems within high-mountain, arctic and polar regions, (ii) considerable inter-and intracatchment variability in the geomorphology and functioning of proglacial systems, (iii) problems with the magnitude of short-term geomorphological changes being at the threshold of detection, (iv) separating short-term variability from longer-term trends, and (v) of the representativeness of plot-scale field measurements for regionalisation and for upscaling. We consider that understanding of future climate change effects on proglacial systems requires holistic process-based modelling to explicitly consider feedbacks and linkages, especially between hillslope and valley-floor components.Such modelling must be informed by a new generation of repeated distributed topographic surveys to detect and quantify short-term geomorphological changes.

“…These surfaces showed evidence of rapid temporal decline in surface sediment response to rainfall events due to surface armouring and sediment exhaustion, resulting in stabilising surfaces within a few decades following deglaciation. Rapid surface sediment reworking and stabilisation were also found to occur within decades of deglaciation following the Little Ice Age maximum as a result of upslope processes (Matthews, 1992;Orwin and Smart, 2004;Moreau et al, 2008), and vegetative colonisation (Moreau et al, 2008;Eichel et al, 2013). As succession progresses, and species composition and the structural complexity of terrestrial plant communities begin to change, sediment mobilisation declines as tensile strength and sediment binding by roots and organic matter (OM) begin to increase (Crocker and Major, 1955;Milner et al, 2007), resulting in increased infiltration and interception of rainfall.…”

Landscapes exposed by glacial retreat provide an ideal natural laboratory to study the processes involved in transforming a highly disturbed, glacially influenced landscape to a stable, diverse ecosystem which supports numerous species and communities. Large-scale vegetation development and changes in sediment availability, used as a proxy for paraglacial adjustment following rapid deglaciation, were assessed using information from remote sensing. Delineation of broad successional vegetation cover types was undertaken using Landsat satellite imagery (covering a 22 year period) to document the rate and trajectory of terrestrial vegetation development. Use of a space-for-time substitution in Glacier Bay National Park, Alaska, allowed 'back-calculation' of the age and stage of development of six catchments over 206 years. The high accuracy (89.2%) of the remotely sensed information used in monitoring successional change allowed detection of a high rate of change in vegetation classes in early successional stages (bare sediment and alder). In contrast, later successional stages (spruce and spruce-hemlock dominated forest) had high vegetation class retention, and low turnover. Modelled rates of vegetation change generally confirmed the estimated rates of successional turnover previously reported. These data, when combined with the known influence of terrestrial succession on soil development and sediment availability, suggest how physical and biological processes interact over time to influence paraglacial adjustment following deglaciation. This study highlights the application of remote sensing of successional chronosequence landscapes to assess the temporal dynamics of paraglacial adjustment following rapid deglaciation and shows the importance of incorporating bio-physical interactions within landscape evolution models.
