Course Description

If you’re planning a stormwater management or green infrastructure practice to infiltrate water into the soil, there are a lot of things to consider before beginning the design and sizing. One key thing to think about is the speed with which water will leave your practice and percolate away.

The many terms used to describe the rate at which water moves through soil can be confusing, and there are a lot of different methods to measure these various parameters.

This interactive, self-directed course can be taken in your own time; it:

  • introduces the terminology including the difference between “infiltration rate” and “hydraulic conductivity”,
  • describes the pros and cons of different measurement techniques, both laboratory tests and in field investigations, and
  • gives recommendations to help develop a sampling strategy.
