(GEOLOGY) A hydrogeologist comes to your property and determines that the aquifer permeability is 45 meters per day and the porosity is 40%. Using the equations below, these values, and hydraulic gradient you calculated above, determine how long, in years, until the contaminated water intersects your well. Assume the contaminant travels at the same velocity as the groundwater.
I am also provided with these values and equations: THANK YOU!
hydraulic gradient= 0.025m
h1 and h2 are 2000m apart
h2 is 150 m above water level and h2 is 200 m above water level.
Average velocity of groundwater= (permeability x hydraulic gradient) / porosity
Time= distance/velocity
