Irrigation and Drainage

In this course you will learn the foundational components of designing, installing, and maintaining irrigation and drainage systems. You will cover case studies using manual and automated sprinkler systems, sprayers and drip irrigation systems, as well as surface and subsoil drainage systems. You will also study efficiently irrigation and drainage principles and practices for a variety of crops, environmental conditions, and soil types in the Pacific Northwest.

What you'll learn

At the end of this course, you should be able to:

  • Solve the physics associated with irrigation system and drainage design and troubleshooting (i.e. power, pressure, friction, and flow).
  • Dissect and identify the various irrigation water sources and components of an irrigation and drainage system.
  • Conduct an irrigation audit, assess the irrigation uniformity value resulting from this audit, and identify methods for improving the irrigation uniformity.
  • Analyze and explain the effects of soil physical properties, environmental conditions, and water quality on irrigation and drainage, and identify methods for improving irrigation application, as well as poor soil and water quality.
  • Select the appropriate irrigation rates, frequencies and timing associated with turfgrass in the PNW.

Turfgrass Management Program

This course is part of the Turfgrass Management Program that includes the following three component courses:

Please note: This course is designed for those working in northern climates such as Oregon and Washington, Europe, Scandinavia and parts of Canada. By focusing on these climates, you'll gain detailed information you can apply to your own park, field or lawn.
