Groundwater

Learning outcomes

After studying this course, you should be able to:

  • use information from wells, the topography of the ground and a water table contour map, to carry out the following: interpret cross-sections, calculate the thickness of the unsaturated zone, and the rate of groundwater flow; deduce the direction in which groundwater is flowing; and estimate the depth to the saline interface in a coastal area from the height of the water table

  • list the types of rock that usually make good aquifers, and assess how good an aquifer a rock could be, given its porosity and hydraulic conductivity

  • distinguish between unconfined and confined aquifers, and recognize conditions in confined aquifers that will produce a flowing artesian well

  • use suitable data to calculate the exploitable storage, specific yield and specific retention of an aquifer.
