Freshwater influx refers to the movement of freshwater into a body of water, such as a river, lake, or ocean. This process can occur through various sources, including rainfall, melting snow, and rivers flowing into larger bodies of water. Freshwater influx is essential for maintaining the balance of ecosystems and supporting aquatic life. The introduction of freshwater can influence the salinity levels in coastal areas, affecting habitats like estuaries and mangroves. Additionally, it plays a crucial role in nutrient cycling, which supports the growth of plants and microorganisms. Understanding freshwater influx is vital for managing water resources and protecting biodiversity.
