Hyporheic Pumping Model

The second model is the Hyporheic Pumping Model. This model simulates the sinusoidal curve of waves which result it in a sinusoidal distribution of head values over a differently shaped soil block.  The head distribution leads to the water from the high head locations (waves) to the low head locations (trenches) In this soil distribution we carry through the soil system found in the permeameter model so that the environments are approximately the same.

What I have so far on the Hyporheic Pumping Model. I have a lot to add.

Permeameter model

Two models were created to test and evaluate the hypothesis formulated for this research project and further understand the conditions of the hyporheic system.  The first model is called the permeameter model. The permeameter model contains two “cylinders” with the smaller cylinder located at the center of the large cylinder and penetrated the soil to a depth of L. No flow boundaries are located between the two cylinders simulating the thickness of the small cylinder. They are also located at the very edge of the system on all sides to contain all flow in the system. The other critical component of this model is that the Head value of the inner cylinder is higher than the other cylinder so that the water flow down the inner cylinder and then up to the surface of the system. MATLAB takes these system conditions as well as the input for different soil cases and outputs the overall system K value (hydraulic conductivity).

I need to talk to you about how much detail I need to go into about what exactly MATLAB calculates. What is necessary to say about the code and what it does?
