Managing the Yellow River: Questions of Borders, Boundaries and Access

, 2006
The Yellow River basin is the site of myriad water resource problems. The Yellow River has natural geomorphological characteristics that include seasonally variable flow, very high sediment load, and the capacity to flood with devastating effect. However,

Cumulative sedimentation hazard map of urban areas subject to hyperconcentrated flash flood: A case study of Suide County in the Wuding River basin, China

Journal of Flood Risk Management
Flash floods can carry substantial sediment, posing significant sedimentation hazards in hilly cities. The sedimentation hazard map can reproduce the sediment thickness and extent of an extreme events scenario, playing an important role in sediment risk ...

In Situ Constructed Magnetic Core‐Shell Hydrogen‐Bonded Organic Framework‐on‐Metal–Organic Framework Structure: an Efficient Catalyst for Peroxymonosulfate Activation

Advanced Functional Materials, EarlyView.
In this work, a magnetic core‐shell catalyst (HOF‐on‐Fe3O4/ZIF‐67) is successfully synthesized, consisting of a metal–organic framework (ZIF‐67) with magnetic Fe3O4 as the core and a porous hydrogen‐bonded organic framework (HOF) as the shell. The catalyst efficiently activated peroxymonosulfate, resulting in rapid and effective removal of water ...

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

Advanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

Study on the dynamic allocation mechanism of water resources in the Yellow River basin considering runoff, sediment and ecosystem

Shui kexue jinzhan, 2021
The 1987 Water Allocation Scheme has been in effect in the Yellow River basin for more than 30 years. This scheme needs to be adjusted dynamically to suit changing flow, sediment, and water use patterns.
