Short summary
Short summary
Many rivers around the world lack direct flow measurements, limiting flood forecasting and water resource management. We developed a new method that combines occasional drone surveys with satellite observations to estimate river flow in poorly monitored areas. When tested on a river in northern Scandinavia, the method produced highly accurate flow estimates and successfully reconstructed an extreme flood event. The approach offers a practical way to improve river monitoring worldwide.

High-altitude lakes in High Mountain Asia (HMA) are important sources of freshwater and sensitive indicators of environmental change. Using satellite data from 2010 to 2024, we examine water level changes in 232 lakes across HMA. Results show rising lake levels on the Tibetan Plateau, while lakes in the Himalaya are declining. These contrasting patterns highlight strong regional differences and provide valuable information for understanding water availability and associated hazards.

The new Surface Water and Ocean Topography (SWOT) satellite represents a leap in satellite-based observations of surface water elevations. We evaluated SWOT’s ability to measure water levels in Danish lakes larger than 0.25km2. We compared data from the SWOT satellite with in-situ station data from 37 lakes. To ensure valid water levels, we tested six methods for selecting SWOT's data. Furthermore, we show that SWOT Pixel Cloud data contains indications of a time-varying residual roll error.

We developed a new statistical approach to track monthly changes in the surface height of the Greenland Ice Sheet using radar data from the CryoSat-2 satellite (2011–2025). The method lets seasonal and long-term variations emerge directly from the data, creating a consistent record of elevation change that helps reveal how Greenland responds to ongoing climate change.

Due to the oversimplification of non-groundwater components, the accuracy of groundwater storage anomaly (GWSA) estimations via the Gravity Recovery and Climate Experiment (GRACE) satellite in most previous studies was questionable. This study developed an improved GRACE-derived GWSA dataset (igGWSA) over global land with full consideration of diverse non-groundwater components. Validation against in situ observations and model simulations demonstrated the high reliability of the dataset.

The objective of this study is to enhance the performance of 1D–2D flood models using satellite Earth observation data. The main factor influencing a 1D–2D flood model is the accuracy of the digital elevation model (DEM). Two workflows are introduced to improve the 1D–2D flood model: (1) in the DEM analysis workflow, 10 DEM products are evaluated using the ICESat-2 ATL08 benchmark, while (2) in the flood map analysis workflow, flood extent maps derived from multi-mission satellite datasets are compared with simulated flood maps.

River flow is experiencing changes under the impacts of climate change and human activities. For example, flood events are occurring more often and are more destructive in many places worldwide. To deal with such issues, hydrologists endeavor to understand the features of extreme events as well as other hydrological changes. One key approach is analyzing flow characteristics, represented by hydrological indices. Building such a comprehensive global large-sample dataset is essential.

A data gap of 338 Chinese reservoirs with their surface water area (SWA), water surface elevation (WSE), and reservoir water storage change (RWSC) during 2010–2021. Validation against the in situ observations of 93 reservoirs indicates the relatively high accuracy and reliability of the datasets. The unique and novel remotely sensed dataset would benefit studies involving many aspects (e.g., hydrological models, water resources related studies, and more).

Global mean sea-level change observed from 1993 to 2016 (mean rate of 3.05 mm yr−1) matches the combined effect of changes in water density (thermal expansion) and ocean mass. Ocean-mass change has been assessed through the contributions from glaciers, ice sheets, and land water storage or directly from satellite data since 2003. Our budget assessments of linear trends and monthly anomalies utilise new datasets and uncertainty characterisations developed within ESA's Climate Change Initiative.

River roughness and geometry are essential to hydraulic river models. However, measurements of these quantities are not available in most rivers globally. Nevertheless, simultaneous calibration of channel geometric parameters and roughness is difficult as they compensate for each other. This study introduces an alternative approach of parameterization and calibration that reduces parameter correlations by combining cross-section geometry and roughness into a conveyance parameter.

Short summary
This paper uses remote sensing data from ICESat-2 to calibrate a 1D hydraulic model. With the model, we can make estimations of discharge and water surface elevation, which are important indicators in flooding risk assessment. ICESat-2 data give an added value, thanks to the 0.7 m resolution, which allows the measurement of narrow river streams. In addition, ICESat-2 provides measurements on the river dry portion geometry that can be included in the model.
