Agricultural Drainage Tile Spacing Calculator

Calculate the optimal spacing between subsurface drainage tiles using the Hooghoudt or Kirkham equation to achieve target water table drawdown in agricultural fields

Each component has a specific meaning:

• Hooghoudt or Kirkham equation — The hooghoudt or kirkham equation recorded for the patient or scenario being assessed.

Note: Interpret the drainage tile spacing result against the clinical thresholds and context described above.

Enter the Hooghoudt or Kirkham equation for the patient or scenario you are assessing. Calculate the optimal spacing between subsurface drainage tiles using the Hooghoudt or Kirkham equation to achieve target water table drawdown in agricultural fields. Use the drainage tile spacing result to inform your clinical assessment.
