alluvial
Left by rivers
Alluvial describes soil, sediment, or land formed by rivers depositing material over time.
An alluvial plain is flat terrain created by centuries of flooding.
Alluvial deposits may contain gold or other minerals washed down from higher ground—hence the connection to prospecting and panning.
The noun is alluvium.
