This study looked at how different types of soil affect the drainage process in areas where the ground is sometimes wet and sometimes dry. They did an experiment with soil columns to see how water moves in sandy and loamy clay soils. They found that sandy soil makes it hard for water to drain into pipes, while loamy clay soil lets water drain better. The type of soil affects how well water can move through it, which can impact how efficiently drainage systems work. By changing the structure of the soil around drainage pipes, we can improve how well they drain water in these mixed wet and dry areas.
