One of the ways to limit the silting process of storage reservoirs could be the use of so-called
preliminary settling tanks. Such concept has
been used in construction of Mściwojów reservoir,
which is the experimental water reservoir
of Wrocław University of Environmental
and Life Sciences. Before infl owing to
the main reservoir water passes through the
chambers of settling tank covered by macrophytes
and subsequently through the pre-dam
where the pollutants and solids are deposited.
This signifi cantly improves the water quality
and slows down the silting process of main
reservoir. The analysis of sediment transport
and sedimentation in Mściwojów reservoir
system (settlement tank – pre-dam – main
reservoir) shows that during the reservoir
operation in 1999–2005 the total amount of
stored sediments is about 26 570 m3. More
than 2/3 of sediments has been stored in predam
and in settling tank. The settlement tank
has retained more than 10% of sediments of
total sediments that infl ow to the reservoir.
While assessing a effectiveness of biological
fi lter in form of vegetation (Common Reed)
in II chamber of settling tank it can be seen
that the most thick layer of about 25 cm has
been deposited there. This layer is a half of
depth in chamber. The chamber is 50% more
shallow than other chambers. It should be
noted that the pre-dam together with settling
tank is an important element of main reservoir
protection against the harmful effects
of sediment infl ow. It also diffuses pollution
infl ow to reservoir from catchment. Vegetation
that was introduced to the tank intensifi
es the process of sedimentation. This paper
presents characteristics and functions of
Mściwojów reservoir system, fi eld research
methodology as well as results obtained and
their analysis.
