Flow
Duration Curve (FDC) is one of the most fundamental tools that provide
information for the design of hydropower projects particularly. Therefore, for
practitioners who deal hydropower design, understanding the flow duration curve
becomes extremely important. The time scales of FDC can be taken as either
daily, ten daily, monthly, or annual. Decision makers decide for the required
time scale of the FDC based on the purpose of hydropower project in
consideration. In this study, FDCs were produced at daily, monthly and annual
time scales from the observed mean streamflow data of a selected gauging
station from the Meric-Ergene river basin in the European part of Turkey. The
data used were obtained from State Hydraulic Works (DSI) of Turkey. Comparison
of flow duration curves at different time scales shows that FDCs at shorter
time intervals look more beneficial in getting more accurate quantiles needed
for hydropower design. By considering the FDC of the gauging station, it is
possible to produce power duration curves of the hydropower plant which is an
important practical tool.
