Quantifying river morphological changes using multi‐satellite observations and in situ measurements
Earth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.This study integrates optical, radar and altimetry satellite data with river gauge measurements to estimate periodically submerged riverbed topography and quantify morphological change. By linking how often water covers the riverbed with water‐level variations, erosion and deposition patterns are mapped across a reach of Jamuna River.

Performance of ICESat‐2 Precision Pointing Determination
Earth and Space Science, 2021 Global elevations are critical to understanding the Earth's dynamic processes and changing climate. These measurements are best acquired from a space‐based vantage point and are most accurate using laser altimetry technology.

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.Abstract Bathymetry is a critical input to storm surge models on coastlines fronted by lagoon systems, yet few studies explore how variations in bathymetry influence flood impacts, flooded extent, and exposed population across these globally widespread morphologies.

Impacts of Temperature‐ and Stress‐Dependent Rheology on Ice‐Shelf‐Front Bending
Journal of Geophysical Research: Earth Surface, Volume 131, Issue 3, March 2026.Abstract Classical treatments of ice‐shelf bending suggest that shelf fronts should bend downwards, due to the distribution of hydrostatic water pressure at the front. However, LiDAR data show several instances of upward‐bending ice‐shelf fronts. While this phenomenon has often been attributed to a buoyant force from a submerged ice bench, recent work ...

Monitoring Flood Inundation Dynamics From Space
Reviews of Geophysics, Volume 64, Issue 1, March 2026.Abstract With the increasing intensity and frequency of flood events worldwide, the need for accurate and timely inundation mapping has never been more critical. Large‐scale flood extent estimations are vital for coordinating effective disaster response, facilitating recovery, and building future resilience.
