The article explores how water moves into soil when it's flooded on and off. They did six experiments in a lab, comparing continuous flooding to on-and-off flooding. They found that soil absorbs more water with on-and-off flooding, especially when the off periods are short. The amount of water the soil can hold stays the same after a few cycles of flooding. Also, the rate at which water goes into the soil is similar with both continuous and on-and-off flooding after a while.
