Abstract
Dams
which needed to drinking and irrigation water supply, flood control etc. at
first have undertaken an another task with hydroelectric power which emerged
from the increasing energy demand due to population growth, technological
developments and changes in consumption habits in recent years. This process
has accelerated from the 1980s which was the beginning of the increasing trends
in renewable energy sources due to the environmental impacts of fossil fuels.
However, even though dam type hydroelectric power plant project is a renewable
energy, it has some adverse effects on ecosystems. The changing flow regime
with the intervention to the river generally results in destruction and
fragmentation in the riparian ecosystem. This change in the land cover can lead
to modification on the microclimate, thus it can change the hydrological cycle
of the basin. For this reason, the monitoring of the change in the land cover
at the dam and its surroundings is important for revealing the effects of the
project. In this context the Hasanlar Dam in Düzce province was examined in the scope of this study. The
land cover change has been determined in two temporal periods through 1:25000
scale topographic maps date on 1960, 1982 and 2013. The land cover which is
consist of 4 classes was obtained by visual classification method. The amount
of change was determined as the unit by grid method. It was observed that
forest areas showed a decreasing tendency after the dam construction during the
first temporal period but an increase was shown later. On the other hand it has
been determined that non-vegetated areas are transformed into orchard predominantly.
As a result, it has been seen that the proposed method can provide an effective
analysis for the land cover change detection when old dated aerial photos or
satellite images can not be reached.
