• Bar
A shoal that develops at the mouth of a river as sediment carried by the river is deposited as the current slows or is impedded by wave action.

• Spring
The point at which a stream emerges from an underground course through unconsolidated sediments or through caves. A stream can, especially with caves, flow aboveground for part of its course, and underground for part of its course.
