Summary: This study evaluates the impacts of land use/land cover and climate change on hydrology and soil erosion processes in a humid tropical region in India. Using the SHETRAN model, the researchers compare past land use maps and climate data with future climate scenarios. The results show that land use, climate variability, and combined effects have different influences on streamflow and sediment load. The projections from a general circulation model indicate an increase in temperature, precipitation, streamflow, and sediment load in the future. The SHETRAN model proves to be effective in assessing the impact of climate change on hydrology and sediment yield, providing valuable insights for future river basin management.

Summary: This study utilized suspended sediment yield field data measured by the national and regional hydrological services to investigate the factors influencing sediment yield in Italy. The research found a wide variation in sediment yield and attributed the marked decrease in sediment yield in Italy to factors such as reduced annual precipitation and forest expansion.

Summary: Climate change affects hydrologic cycle and sediment movement. Researchers use ensemble climate models to reduce uncertainty, but these scenarios may have negative biases. Subset ensembles can accurately reflect overall results within a smaller range.

Summary: Suspended sediment yields from glacierized catchments can be highly variable, with extreme events contributing significantly to the overall sediment flux. Different sediment sources can dominate during specific weather conditions and locations within the catchment, highlighting the complex sediment dynamics in glacierized mountain rivers.

Summary: The study found that climate change has led to an increase in precipitation and temperatures in the Pulangi River Basin, resulting in higher sediment yield and runoff, exacerbating the threat of floods and soil erosion.

Summary: The High-Resolution Model Intercomparison Project aims to improve climate models, but their suitability for hydrologic applications is not well understood. This study simulates annual maximum discharge in river communities across Iowa using HighResMIP outputs, finding that runoff-based simulations capture flood peaks accurately. Bias correction and downscaling methods effectively improve the precipitation data for all models, and while there may not be significant changes in flood peak magnitude, there are indications of increased variability.

Summary: The study explores the factors influencing sediment fluxes in the Northern Caucasus region and finds that sediment loads have generally decreased with non-linear variations. Correlation analyses show that variations in sediment loads are mainly explained by gauging station altitude, differences in land use (e.g. cropland fraction), and catchment area.

Summary: Soil is a critical resource that supports ecosystem services and human needs. Land degradation processes such as erosion and increased sediment loads impact downstream environments. Existing erosion and sediment load models are inadequate for assessing the effects of climate change. A new modelling framework is introduced that estimates sediment load changes under future climate conditions and highlights the importance of recognizing spatial variations in erosion processes and catchment loads.

Summary: The livelihoods of millions of people living in the world's deltas are deeply interconnected with sediment dynamics, however, large dams threaten the supply of sediment from upstream. Dam construction has led to historical sediment flux declines and will increase sediment trapping in the future, potentially causing damaging consequences for local livelihoods and ecosystems.

Summary: The future projection of tropical cyclone frequency is highly uncertain. Recent studies suggest that the spread of seed patterns is correlated with the spread of cyclone patterns. The relationship between seed frequency and climate perturbations can be explained using a downscaling theory.

Summary: The study evaluated the hydrologic and surface erosion effects of forest road in South Fork Caspar Creek using a two-step approach. Statistical analysis showed that road characteristics, peak flow of road runoff events, turbidity, and road dimensions were key factors in predicting suspended sediment load. DHSVM simulations indicated that the 2018 road network had minimal impact compared to the pre-1974 road network on hydrologic and suspended sediment effects.

Summary: This study improved a distributed regional land surface model to evaluate the impacts of climate and land use changes on soil erosion and sediment yield in the Mississippi River Basin (MRB) over the past century. The results showed that despite no significant increase in annual precipitation and runoff, sediment yield significantly increased during 1980-2018, mainly driven by intensified extreme precipitation. Land use change played a critical role in determining sediment yield in the early 20th century, while climate variability became the dominant driver in recent decades. Extreme climate is increasingly affecting soil erosion and sedimentation, emphasizing the need to revisit existing Best Management Practices for water quality in the MRB.
