Question

A confined aquifer with width (W) perpendicular to flow of 4000 m and depth (D) of 45 m has a hydraulic head drop of 1.1 m for every 2200 m of aquifer in the direction of flow. The groundwater age at a distance (L) of 12000 m from the inflow area was determined to be 260 years. If K = 7 m/d, calculate the effective porosity.

Step 1

It can be calculated using the formula: i = (h2 - h1) / L Given that the hydraulic head drop (h2 - h1) is 1.1 m and the distance (L) is 2200 m, we can substitute these values into the formula to calculate the hydraulic gradient: i = (1.1 m) / (2200 m) = 0.0005 Show more…
