Why is sediment transport important in coastal systems?

Sediment transport plays a crucial role in coastal systems primarily because it helps to maintain beach systems and supports various habitats. As sediment is moved along the coastline by processes such as wave action, currents, and wind, it contributes to the construction and nourishment of beaches. This dynamic process ensures that beaches can adapt to changes in sea level and storm events, preventing erosion and loss of land.

Furthermore, sediment transport is vital for creating and sustaining diverse ecosystems. Sediment provides essential nutrients that support vegetation and wildlife, making coastal areas rich in biodiversity. Marshes, estuaries, and mangroves, which are often found in coastal regions, rely on sediment for their development and stability. Therefore, the maintenance of these habitats is directly linked to effective sediment transport processes, highlighting their importance in coastal systems.
