Question

Ground water flows through an aquifer with a cross-sectional area of $1.0\times {10}^{4}m$and a length of 1500 m. Hydraulic heads are 300 m and 250 m at the ground water entry and exit points in the aquifer respectively. Ground water discharge into stream at the rate of $1500m^3/day.$ The corresponding hydraulic conductivity of this aquifer will be

• A. 3.5 m/day
• B. 4.5 m/day
• C. 5.0 m/day
• D. 5.5 m/day

Answer 1

The correct option is B 4.5 m/day

$\text{Discharge,}Q=kiA1500=k\times \frac{(300-250)}{1500}\times {10}^4\therefore k=4.5m/day$
