Sedimentation
Definition
Sedimentation is the process by which particles settle out of a fluid (such as water) and accumulate at the bottom over time. It occurs when suspended particles become too heavy to remain in suspension and sink down due to gravity.
Analogy
Imagine stirring up muddy water in a glass and then letting it sit undisturbed for some time. Eventually, you'll notice that all the dirt particles settle at the bottom, leaving clear water on top. This settling process is similar to sedimentation that occurs naturally in bodies of water.
Related terms
Erosion: Erosion refers to the wearing away and removal of soil or rock materials by natural forces such as wind, rain, or flowing water.
Deposition: Deposition happens when eroded sediments are dropped or laid down in a new location, often due to a decrease in the speed or energy of the transporting agent (e.g., water or wind).
Turbidity: Turbidity is a measure of how cloudy or murky water appears due to the presence of suspended particles. High turbidity levels can indicate increased sedimentation.
