Soil conservation measures reduce harmful sediment flow into Yellow River.
The article discusses how to reduce sediment flowing into the Yellow River by analyzing water and sediment supply trends in gullied hilly loess areas. The researchers found that the sediment transport capacity of the river is lower than the sediment supply rate, and runoff is characterized by short bursts of excess rainfall. To address this issue, they suggest implementing soil and water conservation measures like terracing slopes and building earth dams to trap runoff during flood seasons. These measures help keep harmful sediment on slopes and in ditches, benefiting sustainable development in North West China and reducing sedimentation downstream in the Yellow River.
