The researchers tested different ways of watering crops to see which one worked best. They used a computer model to figure out the best way to water the fields. They found that using a method called alternate furrow irrigation made the water spread out more evenly in the field. This method improved the water distribution by around 9.67% on gentle slopes, 3.16% on medium slopes, and 3.44% on steep slopes. The computer model they used was pretty accurate, with only a small error. They also looked at different factors like the slope of the field, how fast the water flows in, and how long the furrows are to find the best combination for watering the crops.
