From 2012 to 2014, the riverbed materials changed with the erosion and deposition conditions in the river reach. Gravel and pebbles were still the main components of the riverbed materials. The content of sand particles less than 2 mm was low. In 2015, due to the reduction in incoming sand from upstream, weak scouring occurred in the …
This paper focuses on ancient landslides located along the Jinsha River between the Ahai hydropower station (AHHs) and Liyuan hydropower station (LYHs). High-precision landslide monitoring and accurate understanding of inducing factors are important for landslide stability analysis. However, it is often difficult to monitor and analyze …
Scientific Reports - Drone-based investigation of natural restoration of vegetation in the water level fluctuation zone of cascade reservoirs in Jinsha River
The climate change and Land Use/Land Cover (LULC) change both have an important impact on the rainfall-runoff processes. How to quantitatively distinguish and predict the impacts of the above two factors has been a hot spot and frontier issue in the field of hydrology and water resources. In this research, the SWAT (Soil and Water …
The incision rate in the lower Jinsha River is lower, with a maximum value of 2.23 mm/yr, which is lower than the incision rate in the upstream and source areas, and most results are in the range of 0.1–1 mm/yr. The river valley here begins to become …
