SWOT Satellite Observations of the Kakhovka Dam Break Flood Highlight Limitations of Outburst Flood Models

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The 6 June 2023 failure of the Kakhovka Dam generated a catastrophic outburst flood, leading to loss of life and infrastructure damage. During the flood, daily measurements of water surface elevation were collected by the SWOT satellite, providing the first direct, high‐resolution 2D measurements of a large outburst flood.

An Assessment of Regional ICESat‐2 Sea‐Level Trends

, 2021
Sea-level rise is an important indicator of ongoing climate change and well observed by satellite altimetry. However, observations from conventional altimetry degrade at the coast where regional sea-level changes can deviate from the open-ocean and ...

Mechanisms of Surface Meltwater Ponding and Drainage on the Greenland Ice Sheet Revealed Using SkySat Imagery and Deep Learning

AGU Advances, Volume 7, Issue 2, April 2026.
Abstract Surface meltwater impacts Greenland Ice Sheet mass balance indirectly by reducing albedo and promoting hydrofracture. However, fully understanding both processes requires accurate mapping of small‐scale features such as ponds, channels, and moulins that govern meltwater formation and drainage. Here we investigate surface water dynamics at high

Alignment filtering of ICESat flight data [PDF]

, 2013
textICESat consisted of the Geoscience Laser Altimeter System (GLAS) and a commercial spacecraft bus. The stability of the GLAS to bus alignment was unknown and significant for GLAS pointing.

ICESat‐2 Meltwater Depth Estimates: Application to Surface Melt on Amery Ice Shelf, East Antarctica

, 2021
Surface melting occurs during summer on the Antarctic and Greenland ice sheets, but the volume of stored surface meltwater has been difficult to quantify due to a lack of accurate depth estimates.

Runoff Capture by Sea Level Rise Alters the Area, Geometry, and Quantity of Coastal Catchments

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract Coastal catchments, which drain directly to the sea, mediate material fluxes across the land‐sea interface and support species diversity and economic activity in coastal zones. Here, we explore the evolution of coastal catchment divides at the local to global scale from 2000 to 2120 under multiple SLR scenarios using state‐of‐the‐art digital ...

Assessment of SWOT for Monitoring Ice‐Marginal Lake Water Levels in Greenland

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract The Surface Water and Ocean Topography (SWOT) satellite mission provides a powerful data set for monitoring global surface water resources. However, its performance for monitoring ice‐marginal lakes in Greenland remains unknown. Due to the scarcity of in situ measurements, this study evaluated the reliability of ice‐marginal lake elevations ...

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.
