deltaic
Like sediment fans
Deltaic describes something relating to or characteristic of a river delta—the fan-shaped landform created where a river deposits sediment as it enters a larger body of water.
The term appears mainly in geology and geography: deltaic sediments, deltaic plain, deltaic deposits.
The deltaic environment supports diverse ecosystems where freshwater meets the sea.
