We recently used overhead sprinkler systems for irrigation during our field research, which involved biochar & fertilizer trial on morning glory. We collected sprinklers spray water samples (ml) for 30-day after each time we irrigated and we would like to analyze these to show the irrigation spray distribution and uniformity. Which statistical approach/application would you recommend? We would like to show this in a graphic form, however, not in table. We currently have the data points in tabular form. Thanks for your insights.

Pilesorts statistical analysis is one approach I am thinking to use by dividing the collectors into four quadrants according to the cardinal points (East, West, North, and South) and how the collectors were distributed in each of these quadrants and then adding the respective collector IDs and the numerical data for each spray collector per quadrant. We installed 120 spray collectors [see pictures attached] and measured the water content in ml after each irrigation event, but I was thinking there could be an other way to graph this.
Hello All,
I was able to come across a really useful link, which contains some cool, free, and really easy to use statistical application for irrigation water management plan and I thought this could be of use to some of you now or in the future. As per my initial question, from the list of applications I will try the AACALC7 - [very comprehensive hydraulics analysis of sprinkler/spray systems] available and can be downloaded at http://freehc.net.
Thank you all. However, recommendations/comments are still welcome. Try to visit the link and explore some of their cool free software.

Yes, the spray patterns overlap. However, wind speed and direction played a role in this.
Some details include:
We installed 10 Overhead Sprinkler Systems with 0-360° spray angle at heights of 2m (to increase coverage area and reduce spray density) at height of 1m, this pattern is the opposite. The sprinklers flow rate is 0.6-1.62m3/h and spray radius of 5m. Each sprinkler was installed at a distance of 5m apart providing an overlaying 360° spray coverage.
