Diversion
of river water as restoration and management strategy of pit lakes
– potentials and limitations
Martin Schultze, Helmut
Klapper
The diversion of river water into pit lakes is use for
the primary filling of such lakes as well as part of the management
strategy of filled pit lakes. One goal among others is the
neutralization of acidic pit lakes. But the diversion of river water
into pit lakes is accompanied by the risk of eutrophication resulting
from the import of nutrients into the lakes by the river water.
The mechanisms of neutralization and the factors
influencing the eutrophication of pit lakes by river water are
discussed. Examples demonstrate that neutralization can fail during
primary filling. Also the safety of neutralization by permanent inflow
of river water into pit lakes may be limited. The majority of examples
indicate no relevant eutrophication risk during primary filling.
Nevertheless there is a risk of eutrophication caused by long-term
inflow of river water.
