University of Central Florida Civil and Environmental Engineering CWR4101 Hydrology Lecture 9 - Groundwater Hydrology

The student should have the ability to;

• Define (and calculate using an equation) the following;
  • Porosity
  • Pressure Head
  • Elevation Head
  • Piezometric Head
  • Permeability
  • Darcy Velocity
  • Seepage Velocity
• List factor which may affect soil permeability and state the effect that they would have on permeability. Be able to state the quantitative relationship of permeability for common soil types (clay, sand, and gravel).
• Define the following;
  • Aquifer
  • Spring
  • Perched Spring
  • Perched Aquifer
  • Aquiclude
  • Aquitard
  • Confined Aquifer
  • Leaky Aquifer
  • Unconfined Aquifer
  • Transmissivity
  • Aquifer Yield
  • Drawdown
  • Conjunctive Use
• For a confined aquifer be able to calculate using an energy balance and Darcy's law (from the appropriate given information)
  • Piezometric Head
  • Velocity of flow
  • Thickness of the Aquifer
  • Flowrate
  • Permeability of the aquifer
• For an unconfined aquifer be able to apply the Dupuit equation for the calculation of;
  • Flowrate
  • Permeability
  • Piezometric Head
  • Length of flow
• Apply Darcy's law to calculate piezometric head for a unconfined aquifer with uniform infiltration.
• Describe at least 2 methods of drilling a well for the extraction or monitoring of groundwater.
• Calculate the yield of a confined or unconfined aquifer or use yield to calculate permeability.
