Summary: The Galabre catchment, part of the French network of critical zone observatories, was instrumented in 2007 to study suspended sediments dynamics in areas with highly erodible badlands on different lithologies. The site includes meteorological stations, gauging stations, and automatic water sampling systems to quantify sediment fluxes and analyze the links between meteorological forcing and watershed hydrosedimentary response. The measurements were extended to the dissolved phase in 2017 to understand water origin during events and the partitioning between particulate and dissolved fluxes of solutes in the critical zone.

Summary: Under global warming, the permafrost-underlain headwater catchments of the Tibetan Plateau are experiencing permafrost degradation and changes in precipitation characteristics, leading to potential changes in riverine suspended sediment and solute fluxes. This study investigated these fluxes in a permafrost-underlain catchment on the northeastern Tibetan Plateau, revealing that heavy rainfall events significantly contribute to suspended sediment fluxes in summer, while snowmelt mobilizes more suspended sediment fluxes and fewer solute fluxes compared to summer rain. The findings suggest that with future permafrost degradation, solute fluxes may increase while spring suspended sediment flux may decrease.

Summary: At a continental scale, changes in snow ablation events inform regional hydroclimate, affecting streamflow, soil moisture, and groundwater supplies. The study shows a significant decrease in snow ablation frequency over time, with some regions experiencing up to a 75% decline in events, mainly due to reductions in snow cover.

Summary: Estimating snow cover change is crucial for managing water resources in alpine mountainous areas. This study focuses on the Jingou River Basin in China and uses MODIS satellite data and DEM data to analyze the change in snow cover and its impact on runoff. The results show that there has been an increase in temperature and precipitation in the study area, leading to periodic changes in snow cover fraction. The spatial distribution of snow cover days varies across the basin with more days in the south and fewer days in the central region. Temperature has a greater influence on snow cover fraction compared to precipitation.

Summary: This study examines the influence of catchment morphometry, rainfall, and land cover on water quality and material transport in a tropical mountainous watershed. The findings indicate that water quality in headwaters is affected by urbanization, while low-order streams are influenced by forest cover and sub-catchment characteristics. The transport of water, suspended sediment, and nutrients in the main channel is non-conservative and varies depending on the river section.

Summary: The study aimed to improve understanding of spatial and temporal variability of refreezing in the Himalaya. Results showed significant spatial variability of refreezing amounting to 122 mm w.e. annually, with a seasonal altitudinal variability related to air temperature and snow depth. Daily refreezing simulations decreased by 84% compared to hourly simulations, emphasizing the importance of using sub-daily time steps to capture melt-refreeze cycles.

Summary: Sediment fingerprinting is a method used to identify the sources of sediment in a catchment. Traditional approaches require extensive resources for sampling and laboratory analysis. This study proposes the use of UV-VIS absorbance spectra, measured by submersible spectrophotometers, as a rapid and non-destructive method for sediment fingerprinting. Results showed a relatively low deviation between the spatial source contributions using absorbance and sediment budgeting, indicating the potential of this method for sediment tracing in natural environments.

Summary: Spatial and temporal dynamics of rainfall and snowmelt control the availability of water resources in the rain-snow transition zone of the western United States. The sensitivity of spatiotemporal surface water inputs (SWI) across different water years is poorly understood. A study conducted in a headwater catchment in Idaho modeled rainfall and snowpack dynamics for two hydrologically distinct years. The results showed that SWI is influenced by total precipitation, snow drifts, elevation, and slope aspect. The distribution of SWI is expected to change with declining snowfall and redistribution as the climate warms.

Summary: Machine learning algorithms have shown better performance in streamflow prediction compared to traditional hydrological models. In this study, researchers proposed a methodology to test and benchmark ML algorithms using artificial data generated by physically-based hydrological models. They found that deep learning algorithms can correctly identify the relationship between streamflow and rainfall in certain conditions, but fail to outperform traditional prediction methods in other scenarios.

Summary: Combined sewer overflows pose significant threats to public health and the environment, and various strategies have been proposed to mitigate their adverse effects. Smart control strategies have gained traction due to their cost-effectiveness but face challenges in balancing precision and computational efficiency. To address this, we propose exploring machine learning models and the inversion of neural networks for more efficient CSO prediction and optimization.

Summary: This study developed a N-cycling model for lowland rural rivers covered by macrophytes and investigated the N imports, exports, and response to sediment dredging. The findings showed a considerable N retention ability in the study river, with significant N imports from connected rivers and surrounding polders. Sediment dredging increased particulate nitrogen resuspension and settling rates, while decreasing ammonia nitrogen release, denitrification, and macrophyte uptake rates.

Summary: High-resolution climate data is crucial for predicting regional climate and water environment changes. In this study, a two-step downscaling method was developed to enhance the spatial resolution of GCM data and improve the accuracy for small basins. The method combined medium-resolution climate data with high-resolution topographic data to capture spatial and temporal details. The downscaled climate data were then used to simulate the impacts of climate change on hydrology and water quality in a small basin. The results demonstrated the effectiveness of the downscaling method for spatially differentiated simulations.

Summary: Precipitation over the Tibetan Plateau is influenced by systems such as the Asian monsoons, the westerlies, and local circulations. The Indian monsoon, the westerlies, and local circulations are the main systems affecting precipitation over the entire Tibetan Plateau. The East Asian summer monsoon primarily affects the eastern Tibetan Plateau. The Indian monsoon has the greatest influence on precipitation in the southern and central grid cells, while the westerlies have the greatest influence on precipitation in the northern and western grid cells. Local circulations have the strongest influence on the central and eastern grid cells.

Summary: This study investigated the distribution and transformation of dissolved organic nitrogen (DON) in riverbed sediments impacted by effluent discharge. The authors found that the spectral characteristics of dissolved organic matter (DOM) in surface water and sediment porewater could be used to predict DON variations in riverbed sediments. Random forest and extreme gradient boosting machine learning methods were employed to provide accurate predictions of DON content and properties at different depths. These findings have important implications for wastewater discharge management and river health.
