When It Rains, It Pours: Introducing Pour Points https://eos.org/editor-highlights/when-it-rains-it-pours paper: https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2023WR035458

"When #rainfall that is collected on leaves and branches eventually falls to the ground, this occurs at so called #PourPoints at the confluence of smaller branches and where branches change their angle. These pour points can produce drip rates that are up to 15 times larger than the rain intensity. This is an important insight to consider in hydrological modeling and #forest #ecology."

When It Rains, It Pours!

Water that falls on a forest canopy during rainfall events reaches the ground at focused locations called β€œpour points”. This insight has a major impact on how we view hydrologic processes on the ground.

Pour points: A novel method for woodland water resource management

Vegetation plays a vital role in regulating the percentage of precipitation reaching the ground to nourish the root systems of plants both in the canopy and undergrowth, which consequently supports the survival of the entire forest ecosystem. Water arrives to the ground via multiple mechanisms, including throughfall (water falling directly through the canopy) or stemflow (water flowing down stems and trunks), while some is intercepted by the canopy leaves and does not reach ground level.
