The Jinsha River Basin in China has seen changes in water flow and sediment levels over the past 50 years. Different regions of the basin have experienced varying levels of water discharge and sediment load, influenced by factors like precipitation and human activities. The construction of reservoirs and water conservation projects have played a significant role in altering sediment levels. From 1998 to 2015, there was a notable decrease in sediment load, mainly due to human activities. This reduction can lead to less sediment buildup in reservoirs and rivers downstream, impacting the environment in the region.
