 Diving Deep into Ground Infiltration Modelling ๐ŸŒ๐Ÿ’ง๐ŸŒฑ

Ground Infiltration Model Overview ๐Ÿ“š✨
At the heart of InfoWorks ICM, we find a sophisticated double reservoir model that paints a vivid picture of both rainfall-induced infiltration and groundwater infiltration. Representing the very essence of the earth's layers, these reservoirs symbolize soil storage and ground storage respectively. But what about those dry days or tidal influences? No worries! Dry weather infiltration and tidal infiltration are also included, leaving their mark on the groundwater table. ๐ŸŒฆ️๐ŸŒต๐ŸŒŠ



Though the model might seem simplified at first glance, it's rooted in the intricate dance of bulk mass balance equations and flow equations. This blend captures the nuances of the physical world around us. However, a little calibration magic might be needed to truly capture the essence. ๐Ÿง™‍♂️๐Ÿ”ง

Rain, Runoff and the Ground Beneath ๐ŸŒง️๐Ÿž️
Rainfall doesn't just wet the ground; it's the starting point of a journey. There are three pivotal pillars when it comes to rainfall runoff:

  1. Initial loss (a.k.a depression storage ๐Ÿฅค),
  2. The volume of runoff ๐ŸŒŠ, and
  3. Routing that runoff ๐ŸŒ.

As rain kisses the earth, it's first stored in surface depressions, which might evaporate over time. But once these depressions have had their fill, the game changes. The overflow now takes two paths: some rushes as runoff, and the rest seeps into the soil storage reservoir. ๐ŸŒ๐Ÿ’ฆ

Now, here's where things get interesting. When our soil reservoir is saturated to its brink, it sends water deeper down. Some of this water might sneak directly into our drainage network, while the rest feeds the groundwater storage reservoir. But remember, the water in the soil isn't just chilling – it's also facing evaporation, albeit at a snail's pace. ๐ŸŒ๐ŸŒฑ

Groundwater – The Silent Mover ๐ŸŒŠ๐Ÿ”
Our groundwater storage reservoir is a hub of activity. Once it's filled to a certain point, it starts losing water as baseflow. And when the groundwater level rises even more, infiltration kicks in. One of the gems of this model is its calibration ability: the groundwater storage level can be aligned with the real-world groundwater table. This sets the stage for realistic infiltration levels, especially when tied to the node that a particular subcatchment drains into. ๐Ÿ“ˆ๐ŸŒ

For those locales where tides play a dominant role in infiltration, there's room for customization. Users can define a time-varying profile for the groundwater storage level. When this is in place, it takes precedence, guiding groundwater infiltration based on its rhythmic undulations. ๐ŸŒŠ๐Ÿ”„

Breaking Down the Equations ๐Ÿงฎ๐Ÿ“
InfoWorks ICM is more than just concepts; it's grounded in robust mathematical equations. From modelling the initial storage of rainwater in depressions to the complex dynamics of the soil and ground reservoirs, each step is quantified. These equations, rooted in real-world physics, help model everything from the percolation of water to the losses from evaporation and baseflow. And for those who love to dive into the nitty-gritty, there are detailed equations for each step, ensuring that the model is both comprehensive and precise. ๐Ÿ“Š๐Ÿ”

The Takeaway ๐Ÿ“Œ๐ŸŒŸ
Ground infiltration is a complex yet fascinating dance of water, soil, and the forces of nature. InfoWorks ICM, with its blend of concepts, models, and equations, offers a window into this world, ensuring that we can model, predict, and understand the myriad ways in which water moves through our world. Whether you're a researcher, an engineer, or just someone fascinated by the world of hydrology, InfoWorks ICM offers a treasure trove of insights waiting to be explored. Dive in! ๐ŸŒ๐Ÿ’ง๐Ÿ“˜
