Diversion ditches and channels – Mine Closure

One of the solutions to keep waters with different quality separated is to construct diversion ditches and channels (Lottermoser 2007, Wolkersdorfer 2008, ITRC 2015). The diversion structures divert surface water around potential inflow zones, such as seeping places or fracture zones, and can be extremely useful to minimize post closure impacts.
