Sediment yield refers to the amount of sediment that is transported by water as it flows through rivers, streams, and other water bodies. This sediment can come from natural sources such as erosion of rocks and soils, or from human activities such as construction, agriculture, and deforestation. Sediment yield is an important environmental concern as it can impact water quality, aquatic habitats, and infrastructure, as well as contribute to flooding and erosion. Research in this area focuses on understanding the factors that influence sediment yield, developing models to predict sediment movement, and implementing strategies to mitigate its negative impacts on the environment.
