Question

Hello! I have a question about assumptions that are made when drawing flow nets. This is the question: Write out the groundwater equation that corresponds to the flow net solution. Then list 8 assumptions associated with this equation. My problem is that I'm not sure if i'm on the right track. I would appreciate if someone could proofread my work. This is what I have so far:

equation: Q=(K)(dh/dL)(A)

1. The aquifer is homogenous. (homogenous material)

2. The aquifer is isotropic. (isotropic hydraulic conductivity)

3. The aquifer is fully saturated.

4. There is no change in the potential field over time.

5. The flow is laminar.

6. Fluid is a constant density.

7. All boundary conditions are known.

8. Flow net is drawn parallel to flow.

Explanation / Answer

The equation and assumption is correct.

Darcy's law is valid . This is also considered as an assumption in this case.

Flow into the zone is equal to the flow out of the zone.

The equation can also be written as Q = QaNf = KH Nf/Nd

this is Total Q per unit width H is the total head loss.
