Levelling Info #Levelling #survey | Surveying Engineering Design Information

Levelling, smoothing and shaping the field surface is as important to the surface system as the design of laterals, manifolds, risers and outlets is for sprinkler or trickle irrigation systems. It is a process for ensuring that the depths and discharge variations over the field are relatively uniform and, as a result, the water distributions in the root zone are also uniform. These field operations are required nearly every cropping season, particularly where substantial cultivation following ha
