What is a drainage coefficient? The term drainage coefficient stands for the theoretical maximum rate of water removed from a field over a period of time. In the United States, we use the …

This tool calculates the three standard coefficients (drainage rates) recommended by Skaggs (2017) for characterizing the hydraulics of subsurface drainage systems.

The drainage system capacity selected for most northern Midwest farmlands should provide the desired amount of water removal per day, commonly referred to as the drainage coefficient.

Mar 25, 2025 · A drainage coefficient quantifies the efficiency of a drainage system, representing the volume of water that can be drained from a specific area over a given period.

Jun 11, 2025 · The drainage coefficient is defined as the rate at which water is removed from a given area, typically measured in mm/day or inches/day. It is a critical parameter in irrigation …

The drainage coefficient is the design capacity of the drainage system and is typically expressed as a depth of water removed in 24 hours (inches/day). A drainage coefficient should be …

The University of Minnesota defines the Drainage Coefficient as: “The desired amount of water removed in terms of 24 hours”. Example: a 3/8” coefficient means that a subsurface tile …

Our drainage calculator was developed in partnership with the University of Minnesota Extension to assist you in the preliminary design and understanding of your drainage needs.

Calculating drainage (also called storm water runoff) may sound dificult, but it is actually quick and easy to do. By following the steps outlined in this article, you will be able to determine the …
