Topographic Recontouring
nounPronunciation: /ˌtɑːpoʊˈɡræfɪk ˌriːkənˈtʊrɪŋ/
The process of reshaping mine landscapes to eliminate steep slopes, reduce erosion potential, and restore drainage patterns compatible with post-mining land use. This engineering intervention creates geomorphologically stable configurations that support vegetation establishment.
Plain English
Reshaping the surface of mined land to reduce steepness, improve drainage, and prevent erosion.
Etymology & History
Usage
"Topographic recontouring of the open pit reduced surface angles from 35 degrees to 18 degrees, improving long-term stability."
Style guide notes: Always reference slope angles in horizontal:vertical ratios when documenting recontouring specifications.

Frequently Asked Questions
What slope angles are considered safe after topographic recontouring?
Final slopes typically range from 3:1 to 5:1 (18-11 degrees) depending on material composition and climate.
How much does topographic recontouring cost per acre?
Costs range from $5,000 to $25,000 per acre depending on site complexity, equipment availability, and material movement distances.
Why Test Candidates on This?
Topographic recontouring is essential knowledge for reclamation design and is commonly tested in site assessment and remediation planning.
