Permanent nearshore sediment loss and inevitable retreat of cohesive bluff‐backed beaches
Net volume in survey control areas at the dune‐backed beach (PB) and bluff‐backed beach (LD) is shown between surveys (‘interval’), where the first point is the difference between 2012 and 2020 JABLTCX LiDAR surveys. Cumulative totals are shown as square markers. Water levels during the same dates are shown in grey.

The Cordillera Darwin Icefield (CDI) has experienced widespread retreat since the Little Ice Age (LIA, ∼1870 AD). Prior to this, information on outlet glacier dynamics is limited as there are few terrestrial observations and little mapped deglacial ...

Modelling bedload transport at the network scale in a glacier‐fed Alpine river system
We adapted the network‐scale sediment transport and connectivity model D‐CASCADE for Alpine environments and applied it to the Sulden/Solda catchment (Italy). For the first time, we validate the model with continuous bedload measurements at the catchment outlet and evaluate the plausibility of bedload dynamics along the river network with field ...

Impact of changing hydroclimate on bedload yield
We develop and exemplify a rapid screening tool for estimating the impact of climate change on the annual transport of sediment in rivers. Data from small, steep rivers in Scotland suggest that bedload yields could double based on expected changes and may already be far higher than several decades ago.

Holistic analysis of shoreline change and mudbank dynamics across the Guiana coastline
Annual analysis of shoreline change across the entire Guiana coastline, northern South America, including quantification of the rate and nature of alongshore mudbank migration and cross‐shore mangrove establishment and loss was conducted. Identification of other key coastal landforms contributing to exceptional rates of shoreline change across the ...

Coral reef and mangrove interplay during Holocene sea level changes, Belitung Island, Indonesia
The fate of mangroves and coral reefs during the ongoing sea level rise depends not only on our ability to preserve the ecosystems but also on their geological preconditioning. Therefore, strategies to preserve mangrove ecosystems, while undoubtedly essential, wecan only be successful if accounting for their geological history. Abstract Coral reefs and

Envelope surfaces are used to determine paleo‐topographies. We propose a method that involves extracting the points to interpolate by inverting the topography and selecting pixels above a certain catchment area threshold. This method respects the structure of the hydrographic network, is fast and seems applicable to different topographies.

Stress redistribution following landslides: Insights from 3D stress modelling of mountain topography
We present a novel numerical workflow adapting the Finite Cell Method directly to digital elevation models to simulate near‐surface stress fields. The models demonstrate that topographic unloading via slope failure dramatically reduces localized peak shear stresses but actively redistributes elastic loads onto adjacent slopes, driving progressive ...

Fifty years of micro‐erosion metre monitoring at Kaikōura show that the 2016 earthquake more than doubled shore platform erosion rates, transforming intertidal shore platforms into rapidly degrading supratidal marine terraces and reorganising the process and lithological controls that govern rock coast evolution.

Deriving continuous deglaciation chronology from infrequent historical outlines
We present a software tool (R script) that interpolates continuous surfaces of time since deglaciation from historical glacier outlines. At user‐specified points, the results can be used to reconstruct the deglaciation history (distance to glacier surface), including glacier readvances.
