Question

For the graph below, the plume moved 10 meters downgradient every 6 months. The plume concentration was estimated in mg/l for the solute. What was the original plume concentration when the solute was released at time = 0? If you integrate under the curves, the total mass is the same at all four times. What does this indicate about the rate of degradation of the solute? What is the name of this type of solute? What is the advective rate of the groundwater? If the groundwater gradient was halved, what would the advective groundwater velocity be?

Explanation / Answer

c. Advection rate of ground water is the movement of groundwater through the subsurface due to pressure and gravitational energy.

d. Decreased. Because in a single flow the ground water gradient may be very high. But if the ground water gradient is halved, the flow directions and flows also changed so the velocity is decreased.
