Calculate Distribution Uniformity

By inserting the information collected from each catch can in your grid, you can use the calculator below to find the average amount value and the lowest quarter depth, to convert from inches to volume and to determine the overall Distribution Uniformity (DU). If you are not familiar with this calculator, you may want begin by viewing the tutorial. You can also view the video on Overhead Irrigation for a first hand look at how this process is done.
