Summary: River sediment is undergoing significant changes worldwide due to anthropogenic alterations and climate change. A study on the Godavari river in India reveals a dramatic decline in sediment load over the past five decades, primarily influenced by rainfall, land-use patterns, dam constructions, and intensified human activities. Sediment entrapment by reservoirs has led to reduced sediment flux, causing coastal erosion in the Godavari catchment. These findings emphasize the importance of managing reservoirs, land use, and sediment loads to mitigate erosion and maintain coastal ecosystems.

Summary: River-lake systems are crucial to both the ecological environment and societal development, and have been affected by increasing anthropogenic activities. The analysis of water discharge, sediment load, and rainfall data from Dongting Lake showed a significant decrease in sediment load entering the lake, primarily due to increasing human activities. The continuous sediment accumulation in the lake caused a rising water level over the decades, but the completion of the Three Gorges Dam intercepted abundant sediment, leading to a shift from net deposition to net loss of sediment budget in Dongting Lake and consequent decrease in lake level.

Summary: Two decades of drought in the southwestern USA have led to concerns about wind erosion, dust emissions, and their impacts on ecosystems, agriculture, human health, and water supply. The research found that disturbed areas with low soil calcium carbonate content had high sediment transport in dry years, while areas with little disturbance and low bare soil exposure had less erosion. Cattle grazing was identified as a major driver of erosional activity. Predictive maps informed by field data were created to identify eroding areas and prioritize soil surface protection measures.

Summary: Human regulations have significantly affected the hydrogeomorphic processes and functions of silt-laden rivers, such as the braided reach of the lower Yellow River. The construction of the Xiaolangdi Reservoir and river training works have altered the conditions of the river, leading to changes in channel morphology and flood transport capacity. These changes are primarily driven by anthropic flow regime changes and boundary modifications. Managing erosion and deposition processes is crucial for stabilizing silt-laden rivers, requiring integrated management of soil conservation, dam regulation, and floodplain governance at a basin scale. Lessons from the lower Yellow River have important implications for other rivers facing siltation issues, particularly in the Global South.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.
