|Definition :||Soil, sand, and minerals washed from land into water, usually after rain.|
Sediment piles up in reservoirs, rivers and harbors, destroying fish and wildlife habitat, and clouding the water so that sunlight cannot reach aquatic plants. |
Careless farming, mining, and building activities will expose sediment materials, allowing them to wash off the land after rainfall.
