Civil Engineering

Two piezometers are installed 2430 m apart in a confinedaquifer. The head at the first piezometer is measured as 29.1 m andthe head at the second piezometer as 26.7 m. The aquifer has asaturated thickness of 17.3 m, and hydraulic conductivity of8x10-4 m/s, and effective porosity of 0.16.

Determine:

1.1. without any calculation, predict the direction ofgroundwater flow

1.2. the discharge rate through the aquifer in m3/d/mof aquifer width

1.3. the specific discharges (Darcy velocity)

1.4. the pore velocity (seepage velocity)

1.5. the time for water to travel between two piezometers inyears
