Surface water diversion
nounPronunciation: /ˈsɜrfɪs ˈwɔtər daɪˈvɜrʒən/
The engineered redirection of streams, runoff, or precipitation away from exposed mine workings, tailings areas, or reactive material piles. Diversion structures prevent water infiltration into contaminated zones and reduce pollutant mobilization.
Plain English
Building channels or structures to redirect surface water away from mining areas to prevent pollution and erosion.
Etymology & History
Usage
"The reclamation design included surface water diversion channels to prevent contaminated runoff from the heap leach pile from reaching the adjacent river."
Style guide notes: Specify whether 'clean water diversion' or 'contaminated water diversion' to clarify engineering intent.

Frequently Asked Questions
What structures are used for surface water diversion in mine reclamation?
Berms, ditches, French drains, lined channels, and check dams are common structures that direct water away from reactive materials.
How do diversion systems work with treatment systems?
Clean water is diverted away from mine areas, while potentially contaminated water is collected and routed to treatment ponds or systems.
Why Test Candidates on This?
Surface water diversion design appears in mid-level reclamation project planning and civil engineering applications.
