Answer 1

To calculate hydraulic head and hydraulic pressure, use the equations hydraulic head = elevation head + pressure head, and hydraulic pressure = density of water x gravitational acceleration x hydraulic head. To calculate hydraulic gradients, divide the difference in hydraulic head by the distance between wells. To calculate Darcy flux, use Darcy's law: Darcy flux = hydraulic conductivity x hydraulic gradient.

Step-by-step explanation:

In order to calculate the hydraulic head and hydraulic pressure for wells A, B, and C, we need to know the elevation difference between each well and a reference point. Hydraulic head is defined as the total energy per unit weight of fluid, and it can be calculated using the equation:

Hydraulic head = elevation head + pressure head

The hydraulic pressure can be calculated using the equation:

Hydraulic pressure = density of water x gravitational acceleration x hydraulic head

Once we have the hydraulic head and hydraulic pressure for each well, we can calculate the hydraulic gradients between them. The hydraulic gradient between two wells is equal to the difference in hydraulic head divided by the distance between the wells. Finally, to calculate the Darcy flux (groundwater velocity), we can use Darcy's law: Darcy flux = hydraulic conductivity x hydraulic gradient
