Summary: Advancements in geodetic altimetry instruments enable more accurate measurements, which in turn provide useful data for narrow rivers and streams. By combining ICESat-2 measurements with a low-parameterized hydraulic calibration, it is possible to simulate water surface elevation and estimate discharge. The calibrated model allows for the calculation of water surface elevation at any point in the river and the estimation of discharge.

Summary: This study introduces a parameterization of 1D hydrodynamic models by combining cross-section geometry and roughness into one conveyance parameter. By using satellite observations of river width and water surface elevation, the feasibility and performance of this method are illustrated. This approach allows for calibrating flow area and conveyance curves in the absence of direct observations of bathymetry and hydraulic roughness.

Summary: Satellite altimetry monitoring of water bodies is an advanced method, particularly useful in regions with low gauge density like the Indus River in Pakistan. This study validated altimetry-derived water heights with gauge data, revealing high correlations but some deviations. Using moving averages of gauge data significantly improved the results. Validation of satellite-derived water heights allows for observing river level changes in different segments of the river system.

Summary: This study estimated the river discharge of Greenland and provided continuous and long-term discharge observations, filling the data gap caused by the lack of in-situ measurements. The results showed that the proposed method accurately estimated the water extent and had good correlation and fit with the in-situ data. Comparisons with a regional climate model indicated that the model generally underestimated the annual ice sheet melt runoff but overestimated the monthly runoff in July.

Summary: By utilizing radar and laser altimetry techniques along with satellite observations, we successfully derived estimates of relative volume changes from various lakes and reservoirs in South America. Comparisons between different data sources showed good agreement, but also revealed some discrepancies, particularly in snow-covered areas. The latest global iterated mascon solutions demonstrated their accuracy and sensitivity, enabling us to more effectively monitor changes in surface water bodies.

Summary: River discharge is an important hydrological index for the global water cycle and flood/drought forecast. This letter proposes an improved index-velocity method to address the challenge of measuring discharge in mountainous rivers, where the water level changes significantly due to the deep-narrow channel. Experimental results demonstrate that this method achieves higher calculation accuracy and expands the applicability of UHF radar in discharge measurement.

Summary: Non-contact methods are of great significance in the measurement of river discharge, as they can improve efficiency, ensure equipment and personnel safety. However, challenges still exist in measuring river discharge efficiently and accurately due to the requirements of riverbed topography measurements and difficulty in determining hydrological parameters. To overcome these challenges, a new river discharge inversion method is proposed in this paper, which divides vertical velocities into inner and outer region velocities and estimates water depths and river discharges based on velocity distributions. The proposed method shows high efficiency and accuracy in different river widths and water depths without measuring water depth in advance.

Summary: This study utilized Ku-band backscatter measurements from the Jason-2 and Jason-3 satellite missions to demonstrate the potential of radar altimetry for the retrieval of river ice phenology dates and ice thickness for the first time. The results show that the altimetric measurements are sensitive enough to detect the first appearance of ice and the beginning of thermal breakup on the lower Ob River. The study also reveals the uncertainties in ice event timing and river ice thickness retrievals, as well as the novel application of radar altimetry for predicting ice bridge road operations.

Summary: This study found close agreement between radar-based measurements and U.S. Geological Survey measurements, indicating that radar may be a viable tool for monitoring flow conditions leading to bridge pier scour. Additionally, the correlation between ohm and pier scour depth suggests that radar-derived ohm measurements can be used to estimate and predict scour depth.

Summary: The lack of observed rainfall data in African countries poses a major challenge for efficient water resources management. This study evaluates the ability of satellite rainfall products to estimate river runoff in 12 basins in Morocco using four hydrological models. The results show that the combination of the SM2RAIN-ASCAT satellite product and the IHACRES model produced the best results in replicating river runoff, with the highest efficiency criterion and probability of detection. The performance of the hydrological models varied across catchments and satellite rainfall products, emphasizing the importance of careful model selection for specific applications. This evaluation suggests that SM2RAIN-ASCAT could be a reliable alternative to observed rainfall for hydrological modeling.

Summary: Landslides are a significant issue caused by climate change, tectonic activities, and human actions. The frequency of landslides has increased in recent years, leading to severe damage to human life and infrastructure. In this study, a new technique utilizing satellite-derived land cover information was proposed to identify and map landslides. The results demonstrated the effectiveness of this methodology in accurately identifying landslide areas both immediately after the event and months later. The technique was implemented on the Google Earth Engine Platform, making it automated and applicable globally.

Summary: This paper proposes an alternative Background Radiance Estimator based on a Multi-temporal Approach (BREMA) for characterizing background and calculating Fire Radiative Power (FRP), and compares it with the operational product. The results show that BREMA is capable of independently estimating background radiance regardless of cloudiness or smoke presence during the event, and without dependence on fire extent. The possible impact of this approach on estimating CO2 emissions is also evaluated.

Summary: This study investigates the impact of precipitation extremes on hydrological processes in a loess area on China's Loess Plateau. The findings show that thermal-gradient-driven vapor transfer is an important mechanism for deep-layer recharge at the event scale. At the annual scale, extremely wet years result in significantly larger deep-layer recharge compared to extremely dry years. However, extreme changes in climate have limited impacts on evapotranspiration.

Summary: Accurately delineating flood hazard maps is crucial for flood risk management. Flood inundation models, calibrated using limited information from observed flood events, are fundamental for reproducing flood-prone areas. In recent years, Earth Observation data, including high-resolution satellite images, have been used for flood monitoring and emergency response. This study investigates a levee breach in December 2017 and simulates the flood event using a 2D hydraulic model calibrated with satellite imagery, highlighting the importance of high-resolution satellite data for reliable representation of the flooded area.

Summary: Irrigation accounts for a large majority of global freshwater withdrawals and consumptive water use, causing significant impacts on the Earth system. This Review provides a summary of how irrigation currently affects key components of the Earth system. It is estimated that over 3.6 million km(2) of land is currently being irrigated, with hot spots in the US High Plains, California Central Valley, Indo-Gangetic Basin, and northern China. Process-based models estimate that around 2,700 +/- 540 km(3) of irrigation water is withdrawn globally each year, and this is broadly consistent with reported values from countries, despite uncertainties.

Summary: This study investigates the control of pre-storm conditions on runoff coefficients in European basins. The results indicate that precipitation has a relatively good explanatory power for stormflow volumes, but not for peak discharge. The correlation between pre-storm conditions and runoff coefficients varies among different basin types, which is crucial for flood forecasting and model calibration.
