Explanation
Capillary water is held tightly around soil particles and is available to plants. Hygroscopic water forms a thin film around soil particles and is unavailable to plants. Gravity water moves downward through the soil due to gravity and can cause waterlogging when excessive irrigation occurs. Free water is the water in soil pores not held by capillary forces. Therefore, gravity water is responsible for waterlogging as it percolates and raises the groundwater level.
