Irrigation Design — How It Works
Define the finished purpose, reference levels, underlying material condition and the evidence required by the receiving operation. Geometry alone does not establish structural or agronomic performance.
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.
Irrigation Grade Design
Irrigation grade design starts with the method of applying water and the field's soil and supply conditions. Minimising unnecessary soil movement is one consideration alongside water distribution.
Before moving material
Survey the field with inlet and outlet structures.
Receiving operation and checks
Check the formed field and its operating behaviour. Record levels and water observations together.
A single published slope cannot replace site-specific irrigation design.

A drawing becomes useful in the field when its levels, coordinates and version are understood by the people and equipment doing the work. A design may be correct while the machine follows the wrong datum or an outdated file. Resolve that transfer before soil moves.
Before moving material
Agree the coordinate system, vertical datum, benchmark and drawing revision.
Receiving operation and checks
Record changes and return the verified surface information to the designer. Retain the issued design and the as-built check as separate records.
Do not infer a surveyed boundary or certified design from an illustrative terrain model.

Working weight influences cutting, traction and ground loading, but weight alone does not establish grading performance. Ballast, a carried load and attachment weight also change the demands on the tractor, hitch and tyres. Consider the complete combination in both loaded and empty states.
Before moving material
Obtain the machine weights, hitch limits and tractor information.
Receiving operation and checks
Use a controlled trial to establish a workable pass depth. Observe slipping, rutting and unstable handling before chasing greater load.
More weight may damage soft ground and does not make a machine suitable for every tractor.
