Siltation

Siltation refers to the accumulation of silt—finely grained soil or particles—within water bodies like rivers, lakes, and reservoirs. This occurs when soil erosion and runoff transport these particles into water sources, often due to activities like deforestation, agriculture, and construction. Siltation can reduce water depth, harm aquatic habitats, disrupt water flow, and impact water quality, making it challenging for fish and other wildlife to thrive. Managing siltation is essential for maintaining healthy ecosystems and ensuring clean water for human use and biodiversity.
