Multiscale characterization of splays produced by a historic, rain-on-snow flood on a large braided stream (Platte River, Central USA) [PDF]

Earth Surface Processes and Landforms, Volume 49, Issue 14, Page 4788-4807, November 2024.
A historical flood generated 32 splays covering 1,438 ha along a 122 km reach of the braided lower Platte River. 94% of the splays were bank‐top splays deposited on abandoned braid channels presently cultivated for row crops. Splays pose an increasing hazard as rain‐on‐snow floods are becoming more common in the central USA.

Surfaces from the Visual Past: Recovering High-Resolution Terrain Data from Historic Aerial Imagery for Multitemporal Landscape Analysis. [PDF]

J Archaeol Method Theory, 2018
Historic aerial images are invaluable sources of aid to archaeological research. Often collected with large-format photogrammetric quality cameras, these images are potential archives of multidimensional data that can be used to recover information about

Segmentation of topographic change by geomorphic units to assess physical habitat transitions in a restored river [PDF]

, 2020
River restoration schemes that utilise natural processes need to be monitored post-implementation to inform adaptive management, to assess their success at delivering sustained ecological improvements and to contribute to the design of other schemes. All

The Effect of Large Wood Accumulations With Rootwads on Local Geomorphic Changes [PDF]

, 2022
Large wood (LW) can be transported along a river during floods, increasing flood-associated hazards, particularly when it accumulates at river-spanning infrastructures such as bridges and weirs.

Quantification of short‐term transformations of proglacial landforms in a temperate, debris‐charged glacial landsystem, Kvíárjökull, Iceland

Land Degradation &Development, Volume 34, Issue 17, Page 5566-5590, November 2023., 2023
Abstract Proglacial areas are dynamic landscapes and important indicators of geomorphic changes related to climate warming. Systematic and repeat surveys of landforms presently evolving on glacier forelands facilitate the quantification of rates of change and an improved understanding of the processes generating those changes.

Constraints on the Timing and Extent of Deglacial Grounding Line Retreat in West Antarctica

AGU Advances, Volume 4, Issue 2, April 2023., 2023
Abstract Projections of Antarctica's contribution to future sea level rise are associated with significant uncertainty, in part because the observational record is too short to capture long‐term processes necessary to estimate ice mass changes over societally relevant timescales.

Assessing DEM quality and minimizing registration error in repeated geomorphic surveys with multi‐temporal ground truths of invariant features: Application to a long‐term dataset of beach topography and nearshore bathymetry

Earth Surface Processes and Landforms, Volume 47, Issue 12, Page 2950-2971, 30 September 2022., 2022
The field site at Porsmilin and the method we developed for assessing DEM quality and minimizing registration error in repeated geomorphic surveys using a multi‐temporal ground truth of invariant features. In this example, the method is applied to 43 topographic DEMs collected using terrestrial laser‐scanning. Abstract Remotely sensed digital elevation
