A component of the course “Filling the Pipeline: Agricultural Drainage Education to Meet 21st Century Water Management Needs”
Instructor: Dr. Amy Kaleita, Iowa State University
Overview: This module provides an overview of subsurface drainage design elements including layouts, depth and spacing, and pipe diameters, and demonstrates how to calculate these variables for an example field.
After completing this module, students will be able to:
- Understand the alignment of pattern drainage with field topography
- Determine appropriate depth and spacing based on expert guidelines
- Calculate necessary pipe diameter to accomplish recommended drainage
