Irrigation Bay Grade Calculator
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.

An irrigation bay needs a planned relationship between inlet, surface, banks and outlet. Local low areas can retain water while high areas delay its movement.
Before moving material
Record bay dimensions, boundary levels and existing supply/outlet details.
Receiving operation and checks
Recheck levels and observe an irrigation event before declaring the bay complete. Inspect the far end and corners for residual depressions.
No single bay slope or inlet setting suits every soil and water supply.

Cutting, collecting, carrying, placing and grading are different tasks. A machine that drags material forward does not necessarily carry a contained load to a distant low area. Break the earthworks into these actions so the route, implement and checking method match the actual work.
Before moving material
Survey high areas, receiving areas and obstacles before loading.
Receiving operation and checks
Recheck levels before another layer or another operation covers the work. Track the destination of material as well as the appearance of the cut.
Material suitability, safe towing and compaction requirements remain separate decisions.
