Irrigation Contractor — Identify High-Low
Describe the application, material route, growing or working area and proposed rental period. A listed scenario is not a claim that a Dugong rental unit or local service is available.
This reference assembles relevant extracts from the guide library. It is general project planning, not a local project report, verified specification or translated technical publication.
High-to-Low Redistribution
High-to-low redistribution can reduce local quantity imbalance when the high area's material suits the low area's intended use. It should follow measured levels, not visual guesses.
Before moving material
Mark confirmed cut and fill areas and soil layers.
Receiving operation and checks
Prepare the placed material and recheck the profile. Compare productive-layer depth in both source and receiving zones.
Some low areas are designed drains and should not be filled.

Moving soil from high spots to low spots requires a measured surplus and a suitable receiving area. A low patch caused by weak support may need repair before fill.
Before moving material
Check source material and the low area's cause.
Receiving operation and checks
Prepare the receiving layer and restore the source surface. Check both final levels and soil-layer depth.
Avoid filling designed drains or mixing unsuitable subsoil into growing medium.

Irrigation landforming connects the field surface to the method of applying water. The appropriate design depends on the supply, soil and planned operating sequence.
Before moving material
Survey field levels together with water-supply and drainage structures.
Receiving operation and checks
Check the formed field before the next cultivation or irrigation operation. Observe advance and recession of water where practical rather than relying only on a dry appearance.
Landforming is one part of irrigation performance, not a guaranteed efficiency percentage.
