sediments and pollutants transport

Sediments are particles of soil, sand, or minerals carried by water, wind, or ice. Pollutants are harmful substances, like chemicals or waste, that can hitch a ride with these sediments. When water moves—such as in rivers, streams, or rain—it transports both sediments and pollutants downstream. This process can carry impurities into lakes, oceans, or groundwater, affecting water quality and ecosystems. Understanding sediment and pollutant transport helps manage environmental health, as it explains how contaminants spread and where they may accumulate, influencing water management and pollution control strategies.
