Question

With a mean annual discharge of 6,000 acre - feet/year at the springs, what would be the average transmissivity of the aquifer if the width of the aquifer at the well is estimated to be 1.8 miles? Gradient is 0.95%

Answer 1

Answer:

transmissivity =0.0001458235 m² / year

Explanation:

given data

discharge = 6,000 acre - feet/year = 0.001775566 cubic miles

width of aquifer = 1.8 miles

Gradient = 0.95%

to find out

what would be the average transmissivity of the aquifer

solution

we know that transmissivity formula that is

transmissivity = $\frac{Q}{W*i}$

here Q is discharge and W is width and i is gradient

so put here value

transmissivity = $\frac{Q}{W*i}$

transmissivity = $\frac{0.001775566}{1.8*0.45}$

transmissivity =0.0010383427 mile² / year

and we know 1 miles² = 2589988.11 m²

so

transmissivity =0.0001458235 m² / year
