Localised geomorphic response to channel-spanning leaky wooden dams Abstract. The introduction of leaky wooden dams (or engineered log jams or LDs) into river corridors in low-order steams in upper catchments has recently become a popular form of natural flood managem...

🚨 New paper out now in @egu-esurf.bsky.social! 🚨

We explore the geomorphic response of two river reaches to leaky dams, focusing on bathymetric change, planform evolution, water levels, and grain size distribution—helping to address the gap in field studies

Detection of landslide timing, reactivation and precursory motion during the 2018, Lombok, Indonesia earthquake sequence with Sentinel-1 Abstract. Earthquake-triggered landslides can be mapped using optical satellite images, but assessing how they evolve during earthquake sequences is difficult due to cloud cover in these data. This in...

Our new paper @egu-esurf.bsky.social is now online! We used Sentinel-1 SAR to detect landslide activity during an earthquake sequence, demonstrating that InSAR coherence can be used to detect not only new failures but also reactivations and precursory movement. esurf.copernicus.org/articles/13/...

Climatic and Tectonic Forcing Lead to Contrasting Headwater Slope Evolutions Abstract. Landscapes evolve through the coupled effects of tectonics and surface processes. Previous studies have shown that uplift rate changes generate upstream-migrating erosion waves, altering dow...

Hydrodynamic and morphodynamic patterns on a mid-channel intertidal bar in an estuary Abstract. Many estuaries have mid-channel bars that emerge during low tide. In contrast to fringing tidal flats, these bars are fully surrounded by channels. This may lead to different hydrodynamics a...

Decadal in situ hydrological observations and empirical modeling of pressure head in a high-alpine, fractured calcareous rock slope Abstract. In peri- and paraglacial regions, water plays a critical role in the hydrological cycle and slope stability. However, hydrological models often overlook water infiltration into bedrock due t...
