Capillary drainage is the process of draining water from the soil through tiny pores and cracks in the soil particles. It occurs naturally when the soil is soaked with water, and can be used to remove excess water from an area.

Capillary drainage is most commonly used in agricultural applications, as it can help reduce soil erosion and water loss by retaining nutrients and moisture. For example, it can be used to keep fields from becoming too dry or to drain wetlands of excess water. It is also used in landscaping to limit plant damage from flooding or over-watering.

The process of capillary drainage involves the use of capillary action—the movement of water through tiny spaces that are too small for it to flow through by traditional means. This is why it is most commonly seen in soils with small particles, such as clay or silt.

Capillary drainage can be enhanced using various methods, including the use of an impermeable layer of material such as plastic or clay, to prevent water from flowing directly down into the soil. This can be an effective way to help retain water in the soil and reduce runoff.

The use of capillary drainage can also help reduce the amount of nutrients and chemicals released from the soil into ponds and streams. By keeping water stored in the soil, it is kept away from bodies of water and can be used for agricultural purposes instead.

Overall, capillary drainage is a useful tool for farmers, landscapers and water management professionals, as it can help keep soils dry and reduce the damage caused by flooding and over-watering. It is a useful tool for anyone looking to reduce water loss and keep soils healthy.
