Diving into the world of hydrological modeling, the concept of percent routing 🌊💹 plays a pivotal role in determining where the runoff flows. Let's break it down 🧐:
When the percent routing is at its peak, 100%🔝🌟:
- Outlet Only Choice 🌪️🚪: Both impervious 🛣️ and pervious 🌿 zones channel their runoff directly to the grand stage, the outlet node, or the superstar outlet subcatchment.
- Pervious Choice 🌿🚪: Imagine a grand ballroom dance 💃🕺: All (100%) of the guests from the impervious area join the pervious party, and after the dance, they all exit together to the outlet node or the outlet subcatchment.
- Impervious Choice 🛣️🚪: The tables turn! Now, all the green, pervious guests 🌿 are invited to the impervious party 🛣️, and post-celebration, they all make their grand exit to the outlet node or the outlet subcatchment.
When the percent routing is balanced at 50% ⚖️🌓:
- Outlet Only Choice 🌪️🚪: It's straightforward! Both impervious 🛣️ and pervious 🌿 zones continue their journey to the outlet node or outlet subcatchment. Here, the percent routing value wears an invisibility cloak; it doesn't influence the outcome.
- Pervious Choice 🌿🚪: Picture a relay race 🏃♀️🏃♂️: Half (50%) of the impervious team passes the baton to the pervious team. Once the race ends, they move unitedly to the outlet node or the outlet subcatchment. Meanwhile, the other half of the impervious team sprints 🏃♂️ directly to the outlet, not waiting for the baton exchange.
- Impervious Choice 🛣️🚪: The relay race reverses! Half (50%) of the green, pervious team 🌿 hands over the baton to the impervious team 🛣️. After the race, they head together to the outlet node or the outlet subcatchment. Simultaneously, the other half of the pervious team dashes 🏃♀️ straight to the outlet.
In essence, the choice of routing and the percentage play a dynamic duo 🎭 in orchestrating the journey of runoff in the landscape of hydrological modeling. Understanding their dance helps in predicting and managing water flows more effectively! 🌍💧🔍
