Außerdem können diese Schwemmböden größere Mengen an Erzen, Edelmetallen wie Gold und Platin sowie Edelsteine enthalten. Solche sogenannten Seifenlagerstätten können sehr ergiebig sein. Durch einen ebenfalls meist hohen Anteil an organischen Verbindungen sind Alluvialböden in der Regel sehr nährstoffreich. So führt beispielsweise die jährliche Ablagerung von Sedimenten an den Ufern
