Delving into Ground Infiltration in Drainage Systems 🌍💧
Navigating the complex landscape of drainage system flows, it's crucial to acknowledge that they often surpass the combined flows from stormwater runoff and domestic/trade inflows. Enter the often-underestimated factor: Ground Infiltration.
Understanding Ground Infiltration: 🌧️🕳️
When you notice that the flow in drainage systems isn't adding up, it's often due to infiltration. This sneaky infiltrate enters the system through cracks, defects, or porous walls. But here's the catch: unlike the quick response of runoff to rainfall, infiltration inflows are the slow pokes of the flow world.
There are two primary culprits:
Rainfall-Induced Infiltration: 🌦️➡️🌍
After a storm, soil water doesn't just sit tight. Some of it infiltrates directly into the drainage network, impacting flow within hours or even days post-storm.Groundwater Infiltration: 🌊⬇️
Rain doesn't just affect the surface. Some of it dives deeper, reaching the groundwater reservoir. Over weeks or months, this can elevate groundwater levels, leading to groundwater seepage into the drainage system.
Incorporating Infiltration in Simulations: 🖥️🔍
To weave in infiltration dynamics into a network simulation, you'll need to craft one or more ground infiltration records. Each record, identifiable by its unique Ground Infiltration ID, lays out the infiltration data blueprint for specific subcatchments. You'll create and tweak these records in the dedicated Ground Infiltration Grid Window under the Subcatchments Grid. Linking them to subcatchments is a breeze – simply specify the Ground Infiltration ID in the Subcatchment Grid Window. And yes, one Ground Infiltration definition can wear multiple hats, associating with various subcatchments.
The Role of the Ground Infiltration Object: 📜
It's the stalwart that sets the stage, defining the unchanging groundwater traits of the subcatchment.
Ground Infiltration Event – The Time Traveler: 🕐
For those dynamic groundwater infiltration patterns, you'll need a Ground Infiltration Event. It paints a time-lapse picture, detailing how groundwater infiltration behaves over a duration.
