Researchers measured how water moves through different types of soil at various depths in the field. They found that the rate at which water drained from the soil could be predicted accurately using a mathematical equation. The soil's physical properties and texture influenced how water moved through it. The results showed that the calculated values matched well with the actual measurements, and there was no significant delay in water movement. This study helps us understand how soil characteristics affect water flow and drainage, which is important for managing water resources effectively.
