Wrong Fall To Verified Drainage — Material Movement
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.
Poor Surface Drainage
Poor surface drainage can result from a blocked outlet, a reversed fall, a damaged crossing or local depressions. Grading should follow the identified cause.
Before moving material
Trace water from its entry point to the receiving outlet.
Receiving operation and checks
Inspect the drainage route during a suitable water event. Check that the complete route remains connected through boundaries and crossings.
Surface grading cannot remedy every subsurface drainage problem.

Fall is the change in elevation along a defined direction. An incorrect fall can include a reversal, an insufficient gradient or a gradient that differs from the design.
Before moving material
Identify the start and end points, distance and elevation reference.
Receiving operation and checks
Measure the corrected profile independently. Check intermediate points because correct end levels can still hide a local dip.
There is no universal drainage fall appropriate to every project.

A stockpile is a temporary material store, not necessarily a ready-to-use grading supply. Segregation, contamination and mixed layers can develop while material is stored.
Before moving material
Identify the stockpile contents and approved use.
Receiving operation and checks
Grade the receiving area and remove temporary obstructions when appropriate. Check material condition and receiving quantities.
A compact scraper may be useful for placement but not for every stockpile loading task.
