Water return flow is water that finds its way back into a river system or other body of water after being diverted or used. This process is a crucial part of the water cycle and resource management.
Based on the provided reference, water return flow occurs through two primary mechanisms:
Types of Water Return Flow
Understanding the different ways water returns to a source helps explain its movement within the environment.
Here are the two main types of water return flow as described in the reference:
| Type | Mechanism |
|---|---|
| Surface water return flow | This is described as runoff, or water trickling back into the river through channels, drains and creeks. |
| Groundwater return flow | This happens by seeping into the ground, and pushing groundwater into the river. |
Essentially, surface water return flow involves water moving over the land surface, while groundwater return flow involves water soaking into the ground and then moving subsurface towards the river. Both processes replenish the river system, contributing to its overall flow.
