Presentation Transcript

  1. The Wonderful World of Geology • Drilling • Soil identification • Darcy’s Law • Permeameter • Porosity • presented by Jacob Coleman, Kirk Miller, Kelly Barrett, Amanda Margraf Click left mouse button to advance presentation.

  2. Soil ID • There are 4 ways to classify different types of soil. • Moisture Content • Moisture ranges from slightly moist to saturated • Grain size • grain size ranges from silt to gravel • Sorting • is either well sorted or poorly sorted • Color • depends on the organic and mineral content of the soil

  3. Drilling • When drilling you will use the hand auger or a power auger for deeper soil study. • Use the prescribed classification system to identify which zone of the soil you are in. • Unsaturated zone-slightly moist, moist, very moist. • Capillary Fringe-dripping wet • Saturated zone-located below water table

  4. Underground water sampling

  5. An equation for calculating the velocity of groundwater flow. v=K/n(h/L) K= Hydraulic conductivity n=porosity h=change in head L=change in length v=velocity Darcy’s Law v=K/n(h/L)

  6. Permeameter • A device used to calculate the Hydraulic conductivity of your soil sample. • Hydraulic conductivity is a measure of how easy water flows through soil. Return to presentation page
