Practical Methods
How to Establish Fall Across Land
Fall across land is established by relating target elevations to measured horizontal distances. Set the required direction before choosing a gradient or moving soil.
Plan the surface handover
BeforeIdentify start, end and intermediate controls.
Work stageCalculate planned elevation change, compare it with surrounding ground and form the profile without local reversals.
AfterMeasure the constructed surface independently.
What to verify
Check intermediate points and receiving outlets.
Use the method as a planning sequence and adapt it to the actual terrain, material and project requirements. Identify the datum and the stopping point before work, then retain checks that show whether the intended correction was achieved.
Scope and limits
The example calculations on this site illustrate geometry, not universal design slopes.
