Just how does artificial drainage work?
The open trench is the most basic model for an artificial drainage system. Artificial drainage Artificial drainage is the removal and relocation of excess soil water. Once soil has reached the point where it is holding all the water that it is capable of holding, additional water from rain or irrigation will pond on the surface or flow to a lower point. A drainage system provides a passageway for excess water to escape through as it leaves the saturated area. Consider the open trench For the most basic model of a drainage system, picture for a moment a field that is crisscrossed by narrow trenches. Water from neighboring saturated soils or from puddles on the surface will seep into these trenches and flow from the area. Drainage products hold the walls of the trench open while allowing the surface to be covered. Gravity rules! Like natural drainage systems, artificial drainage systems rely on gravity. They cannot draw water “uphill.” Therefore, drainage systems are dependent on continu
