Abstract:
The article examined the ecohydrological aspects of the impact of
small hydropower stations without intra-annual regulation on aquatic
ecosystems and biotopes, which are located in the zone of their
influence on plain rivers.
We chose the zone of the Myhiya hydroelectric power station
influence, which is located on the section of the Southern Bug River
near the Myhiya village in Ukraine. The reports showed that it was possible to fill the tidal base with the water system of the Southern Bug
River in the zone of the HEPS influence at the often without flowing
station, a number of negative environmental aspects were seen, some
of which were negatively visible at the station.
The restoration of the Myhiya hydroelectric power station had a
positive effect on the functioning of the river aquatic ecosystem within
the impact zone, in particular its abiotic components. Water masses in
the studied area, compared with the previous decades, became more
dynamically active, their processes of self-purification were activated.
From the material considered, it can be concluded that the operation of
small hydroelectric power station has virtually no negative impact on
the aquatic environment of the plain rivers and is one of the most
environmentally friendly types of electricity production.
