The researchers developed a new method to measure how quickly soil absorbs water, which is important for managing soil and preventing flash floods. They used a single ring infiltration method and simulated rainfall to determine the soil's sorptivity. By analyzing the data, they were able to calculate the sorptivity accurately. This method provides more precise values compared to traditional methods and gives a better understanding of how soil absorbs water. The results from this new method closely matched theoretical values, showing its effectiveness in determining soil sorptivity.
