Geomorphic changes after the 2021 Central European flood in the Ahr Valley by LiDAR-based differences

Environmental Sciences Europe
Background In July 2021, destructive floods in Western Europe were triggered by enormous precipitation rates related to a low-pressure system named "Bernd." These catastrophic events led not only to major damage to infrastructure, severe economic losses,

Practitioner Readiness: Developing Communities of River Practitioners (CoRPs) to Deliver Proactive Management Practices That Work With the River

WIREs Water, Volume 12, Issue 2, March/April 2025.
ABSTRACT Rapid expansion in the availability of data derived from ground, airborne, and satellite remote sensing, and numerical modeling applications is transforming river science and management practices. This digital revolution has the potential to catalyze the uptake of a riverscapes approach to deliver proactive and adaptive management practices ...

Cascading consequences of structural interventions in a tropical wandering gravel‐bed river

River Research and Applications, Volume 41, Issue 1, Page 120-137, January 2025.
Abstract Riverscapes are often modified and managed through ‘command and control’ structural engineering approaches. These structures not only alter flow and sediment transport patterns but also negatively affect riverscape biodiversity. These impacts are particularly acute for rivers that are characterised by high mobility and wide flow distribution ...

Impacts of Post‐Fire Debris Flows on Fluvial Morphology and Sediment Transport in a California Central Coast Stream

Journal of Geophysical Research: Earth Surface, Volume 129, Issue 12, December 2024.
Abstract Post‐fire debris flows alter impacted fluvial systems, but few studies quantify the magnitude and timing of reach‐scale channel response to these events. In August 2020, the Big Creek watershed along California's central coast burned in the Dolan Fire; in January 2021, an atmospheric river event triggered post‐fire debris flows in steep ...

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

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.

Analysing the impacts of extreme torrential events using multi‐temporal LiDAR datasets—The Schöttlbach catchment, Upper Styria, Austria

Earth Surface Processes and Landforms, Volume 49, Issue 9, Page 2809-2824, July 2024.
The Schöttlbach catchment recorded two major flood events in July 2011 and August 2017. On the basis of reports, geomorphic mapping and the analysis of multi‐temporal LiDAR datasets, we tried to analyse the impacts on the local geomorphic system and constructed an event‐scaled sediment budget for the 2017 event. Abstract Extreme precipitation events in

Short‐term biogeomorphology of a gravel‐bed river: Integrating remote sensing with hydraulic modelling and field analysis

Earth Surface Processes and Landforms, Volume 49, Issue 3, Page 1156-1178, 15 March 2024.
Coupling remote sensing and field measurements with tools for biomass and geomorphological changing mapping and hydrodynamic modelling. Abstract In recent decades, fluvial geomorphology and ecohydraulic research have extensively used field observations, remote sensing or hydrodynamic modelling to understand river systems.

Variations in Subsidence Patterns in the Gulf of Mexico Passive Margin From Airborne‐LiDAR Data and Time Series InSAR: Baton Rouge Case Study

Journal of Geophysical Research: Earth Surface, Volume 129, Issue 2, February 2024.
Abstract The Coast of Louisiana is affected by accelerating sea level rise compounded by land subsidence, leading to land loss. Vertical crustal motions in the region are caused by natural and anthropogenic processes that vary temporally and spatially across the Gulf of Mexico. We investigate the role of growth faulting contributions to subsidence in a
