- The term drainage coefficient stands for the theoretical maximum rate of water
removed from a field over a period of time
- Typical range (0.635 to 1.27 cm/day). The drainage coefficient is the design
capacity of the drainage system and is typically expressed as a depth of water
removed in 24 hours (cm/day). A drainage coefficient should be chosen that will
economically remove excess water from the top part of the root zone within 24 to
48 hours. Climate, soils, and crops grown will all influence the choice of drainage
coefficient, and drainage coefficient choices are typically based on local
conditions, experience, and judgment.
