Flood Inundation Modeling Using the Surface Water Ocean Topography Mission

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract Flood risk mapping requires detailed river bathymetry, yet these data are unavailable for most rivers. We propose a new algorithm to estimate river bathymetry from multitemporal observations of water height by the Surface Water and Ocean Topography (SWOT) mission.

Leveraging ICESat, ICESat‐2, and Landsat for Global‐Scale, Multi‐Decadal Reconstruction of Lake Water Levels

Water Resources Research
AbstractLakes provide important water resources and many essential ecosystem services. Some of Earth's largest lakes recently reached record‐low levels, suggesting increasing threats from climate change and anthropogenic activities. Yet, continuous monitoring of lake levels is challenging at a global scale due to the sparse in situ gauging network and ...

Advancing High‐Resolution Lake Bathymetry Reconstruction Through Geomorphologically Informed Deep Learning in High Mountain Asia

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract Accurate three‐dimensional (3D) lake bathymetry reconstruction is critical for water resources assessment and hydrological modeling yet remains constrained by data scarcity and oversimplified geometric assumptions. To address these challenges, we propose the Geomorphologically informed deep learning (GIDL) framework for high‐resolution 3D lake

Quantifying Permafrost Deformation with ICESat-2

, 2020
We use ICESat-2 laser altimetry crossovers and repeat tracks collected over the North Slope of Alaska to estimate elevation changes due to the deformation of seasonally freezing and thawing permafrost. We compare these measurements with a time series of surface deformation from Sentinel-1 interferometric synthetic aperture radar (InSAR) and demonstrate

Spaceborne LiDAR footprint-level AGB estimation and mapping across forest types using multisource remote sensing and U-Net

International Journal of Digital Earth
Spaceborne light detection and ranging (LiDAR), including ICESat-2 and GEDI, supports large-scale forest aboveground biomass (AGB) mapping, but accurate estimation across heterogeneous forest types remains challenging.

A Software Tool for ICESat and ICESat-2 Laser Altimetry Data Processing, Analysis, and Visualization: Description, Features, and Usage

Software
This paper presents a web-based software tool designed to process, analyze, and visualize satellite laser altimetry data, specifically from the Ice, Cloud, and land Elevation Satellite (ICESat) mission, which collected data from 2003 to 2009, and ICESat-2, which was launched in 2018 and is currently operational.
