 Sediment–water interface

The sediment-water interface, often referred to as the SWI, is the boundary layer where sediment at the bottom of a body of water meets the overlaying water column. This interface is critical in aquatic environments, including lakes, rivers, and oceans, due to several important processes that occur here. ### Key Features of the Sediment-Water Interface: 1. **Nutrient Exchange**: The SWI is a dynamic zone where exchange of nutrients, gases, and organic matter occurs.
