Groundwater moves through a sandstone porous media and is driven by a gradient of -0.05 directed at an angle of 60 degree counterclockwise from the x-axis.
a) assuming an isotropic and homogenous hydraulic conductivity of 0.0001 cm/s what is the magnitude and direction of specific discharge (q)?
b) if the porous media is homogeneous but anisotropic and has a maximum conductivity directed along the x-axis of 0.0001 cm/s and minimum conductivity directed along the y-axis of 0.00005, what is the magnitude and direction of specific discharge (q)?
