Anthropogenic impacts on nutrient variability in the lower Yellow River

Science of The Total Environment, 2021
Excessive nutrient discharges and changes in nutrient ratios caused by global change and anthropogenic activities have been reported in global rivers; however, the actual alterations occurring in the Yellow River environment is too fast to catch up with.

River stabilization reshaped human-nature interactions in the Lower Yellow River Floodplain

Journal of Environmental Management
Floodplains are crucial agricultural and populated areas worldwide. Rivers typically shape human activities within floodplains through water supply and flood risk, forming unique human-nature interaction patterns. Given that river systems have undergone significant transformations globally, understanding the response of these interactions to ...

Distribution of microplastics in surface water of the lower Yellow River near estuary

Science of The Total Environment, 2020
The composition and distribution of microplastics in surface water of the Yellow River lower reach near estuary were investigated in this work. The major shape types of microplastics can be classified to fibers, fragments and particles, and 93.12% of microplastics in the surface water were fibers. The microplastics

Full-stream erosion in the lower Yellow River: Feasibility, sustainability and opportunity

Science of The Total Environment, 2022
The issue of how to achieve removal of recently accumulated sediment is one of the largest unresolved puzzles in China's lower Yellow River. In this work, the feasibility and sustainability of achieving full-stream erosion in the lower Yellow River based on a water-sediment regulation scheme (WSRS) have been comprehensively investigated.

Genomic dynamics of the Lower Yellow River Valley since the Early Neolithic

Current Biology
The Yellow River Delta played a vital role in the development of the Neolithic civilization of China. However, the population history of this region from the Neolithic transitions to the present remains poorly understood due to the lack of ancient human genomes.

Effect of water-sediment regulation operation on sediment grain size and nutrient content in the lower Yellow River

, 2021
The Yellow River (YR) is famous for its high sediment concentration. The Xiaolangdi dam (XLD), the most downstream dam on the mainstream of the YR, plays an integral role in siltation mitigation, flood defence, agriculture, and hydropower generation.

Mineral composition and particle size distribution of river sediment and loess in the middle and lower Yellow River

, 2021
Hyperconcentrated flows often occur in the middle and lower Yellow River (MLYR) and its tributaries, within which the main sediment source originates from the Loess Plateau of China due to serious water erosion.

Application of Fractal Theory in the River Regime in the Lower Yellow River

Applied Mechanics and Materials, 2012
From 1960 to 1999, the river regime in the Lower Yellow River had been the wandering. After the operation of Xiaolangdi Reservoir, the river regime in the Lower Yellow River has experienced some changes because of the reduced discharge and sediment loads. According to the river regime maps, the wandering features of the Lower Yellow River are inhibited
