Introduction to Groundwater Flow Modeling using MODFLOW & GMS: Groundwater Flow Equation | Part 04

In this video, part of our course "Basics of Groundwater Flow Modeling Using MODFLOW, we delve into the groundwater flow equation and explore how MODFLOW solves it using the finite difference method. We will cover the core concepts of the groundwater flow equation without delving too deeply into its proof, focusing instead on its application in different scenarios such as homogeneous, heterogeneous, isotropic, and anisotropic conditions.

We start with a general overview of the groundwater flow equation, which combines the principle of mass conservation and Darcy's Law. You'll learn about the mass conservation principle, where the mass inflow rate minus the mass outflow equals the change in storage over time. We'll represent this using partial derivatives and discuss how various stresses like discharge wells impact the aquifer. Next, we'll discuss Darcy's Law, which helps us determine the inflow rates in different directions based on hydraulic conductivity and changes in head. By combining these principles, we'll derive the general groundwater flow equation, applying it to different conditions such as homogeneous layers, isotropic and anisotropic conditions.

We'll simplify the equation for homogeneous and isotropic conditions, explaining the differences between these terms and their significance in groundwater modeling. You'll see how the equation changes when considering steady-state conditions and how it transforms into the Laplace equation.

By the end of this video, you'll have a solid understanding of the groundwater flow equation, its components, and its simplifications for various scenarios. This foundational knowledge will prepare you for our next video, where we'll explore how the finite difference method works in solving these equations using MODFLOW.
