There are two main things which control groundwater flow. These are the hydraulic gradient and the permeability of the subsurface. We will look at both of these terms and then see how they work together in Darcy’s Law. Finally, we will look at some practical applications of Darcy’s Law.

A brief description of the differences between unconfined aquifers and confined aquifers.
This video describes the difference between the water table and the potentiometric surface in unconfined and confined aquifers.
This video describes some important concepts of pumping wells, including the cone of depression, static/pumping water levels, and drawdown.
How does groundwater flow from one place to another? And how do we tell?

A quick explanation of hydraulic head. I briefly relate head to energy; for a more detailed explanation, check out video 2.
This video describes the concepts of Hydraulic Conductivity and Transmissivity.
