You cannot discuss agricultural hydraulics without discussing pumps. A typical PDF guide on this subject dedicates significant chapters to .

Calcul de la Hauteur Manométrique Totale (HMT) requise :

L'eau est distribuée sous pression sous forme de pluie artificielle.

Not all PDFs are created equal. Avoid poorly scanned 1980s documents. Seek out:

In hilly terrains, farmers can use gravity instead of pumps. Using principles from the PDF, an engineer calculates the flow rate, pipe diameter, and slope needed to ensure the last plant in the row receives adequate water without damaging emitters due to excessive pressure.

Application: If a canal narrows, velocity increases. This prevents sedimentation.

Efficience maximale (> 90 %), réduction des mauvaises herbes, possibilité de fertigation (apport d'engrais via l'eau).
