9.7. Two observation wells were installed along a streamline in an unconfined aquifer 1,000 m (3,280 ft) apart. Compute the time for water to travel from well A to well B if the hydraulic conductivity is 10.0 m/day (32.8 ft/day) and the effective porosity of the aquifer is 0.2. The well information is listed at the top of the next page.
