| For this purpose, the underground drainage structure must be firstly designed and then verified as a subirrigation system. |
| When subirrigation is practiced, water may be needed for twelve to seventy-two hours to subirrigate clear across the bed. |
| With the subirrigation system, there is no need for drainage because there is no excess water. |
| Another involves using a subirrigation system that provides water to plants on an as-needed basis through the geotextile fabric. |
| It is chiefly used in subirrigation systems and has the objective of producing at regular intervals a flow capacity which runs at high speed in order to eliminate sedimentary bodies. |
| Effects of root and subirrigation depth on evaporation and percolation losses. |
