In
recent years, the impacts of climate change on water resources are much more
noticeable. In terms of sustainable management of water resources, it is important
to identify drought occurrences in river basins and to identify drought trends.
For this purpose, many drought indices have been developed in order to define
the droughts quantitatively and Streamflow Drought Index (SDI) method is
frequently used to determine the hydrological droughts among them. In this
study, hydrological drought and trends of these droughts on Acısu, Selendi,
Deliiniş, Demirci sub-basins and Demirköprü Dam reservoir on the Gediz River
are analyzed in monthly, quarterly, six-month and annual time-scales. As a
result of the study, it was determined that the inflows of the Demirköprü Dam
basin were affected from hydrological droughts for long periods and
hydrological droughts were towards the dry periods.
