The study looked at how rainfall and sediment interact in a river with a lot of sediment. They used data from 1971 to 2017 to figure out the best time range to study. They then made models to see how runoff and sediment changed over time at two different spots. They found that the chances of runoff and sediment happening together changed a lot, especially because of things like reservoirs and soil conservation. The results can help manage soil and water better in the region.
