*Tile Drains Spacing, S = 80 (m).
* Flow Rate of Secondary Open Drain, Qopen = 5580 (m³/d).
(a) Qrile 200 (m³/s)
(b)QTile = 300 (m³/s)
(c) Qrile = 186 (m³/s)
2- Given:
* Effective depth of the impermeable layer below Tile Drain level,
*de = 12 (m).
*Hydraulic conductivity of soil layer located above Tile Drains level,
Ka = 6 (m/d).
*
