Gce Model Questions Vol1 2017 Geography Question 18
Practice objective / multiple choice question 18 from the 2017 Gce Model Questions Vol1 Geography examination.
An unconfined aquifer has hydraulic conductivity \(K = 2.5 \times 10^{-5}\ \text{m\ s}^{-1}\) and a hydraulic gradient \(i = 0.0015\). The effective porosity is \(n = 0.35\). The straight‑line distance from a recharge zone to a spring is \(3.2\ \text{km}\). Assuming flow follows the hydraulic gradient directly, calculate the travel time for a water molecule from recharge to the spring, expressing your answer in years (rounded to the nearest whole year).
