We calculated it based on the total amount of water runoff and the desired flow rate. The size of the canal will depend on the slope of the greenhouse floor and the flow rate.
The formula to calculate the cross-sectional area of the canal is:
Canal Area (m²) = Roof Runoff (m³/s) / (Flow Rate (m³/min) / 60)
The depth should be around 15-30 cm, while the width can vary, but it's often around 15-30 cm as well.
