Groundwater 1 Groundwater flows slowly through the voids between grains or the cracks in solid rock. Much of our knowledge depends on field and laboratory.

Presented by: 1. A measure of how easily a fluid (e.g., water) can pass through a porous medium (e.g., soils) 2 Loose soil - easy to flow - high permeability.

Darcy’s experiment: Pressure distribution and head loss in flow through a sand column From Mays, 2011, Ground and Surface Water Hydrology

Determine the hydraulic conductivity of the sample The figure shows a sample from an unconfined aquifer. L=50 cm, Diameter = 6 cm. The sample is tested for 3 min under constant head difference of 16.3 cm. 45.2 cm3 of water is collected at the outlet. Determine the hydraulic conductivity of the sample Determine the average interstitial velocity assuming a porosity of 0.3 Determine the Reynolds number assuming an effective grain size (d10) of 0.037 cm From Mays, 2011, Ground and Surface Water Hydrology
