Term
Resurgence
A place where water that flowed underground returns to the surface, often as a spring in karst terrain. Tracer studies can link a resurgence to a distant sinking stream. The visible outlet does not reveal the whole underground route.
What to look for
Groundwater emerges at a karst spring in Alabama. Water stored in connected pores and fractures can return to the surface as spring flow.
