Due to the limited availability of water resources in nature, development plans are being prepared for
sustainable and effective use of water resources. Water structures are constructed in order to develop and
control water resources in line with needs. Specialized engineering units work in coordination during the
surveying, planning, project design and construction phases of water structure projects. Dam design and
construction works depend on several technical, economic, environmental and social factors and dam project
implementation is a complex task. The details of project elements regarding hydraulic, geotechnical,
structural issues, operation-maintenance works, monitoring, providing dam safety are specified in dam design
and construction guidelines. Dams are structures that control large volumes of water and have a long service
life. Sustainable water resources management and dam safety effects the performance of the project. The
design flood criteria in dam projects depends on safety principles. Flood risk assessments and future
projections are essential in flood management. Flood control during dam construction is essential to prevent
damages of flood disasters. Upstream cofferdams are built as temporary structures to provide safety, flood
protection, diversion and dry environment during construction of permanent structures. It is an important task
to find solutions to flood problems in dam construction sites in order to ensure dam safety. Berdan Dam was
constructed between 1975 and 1984. The dam is located in Mersin City in the Eastern Mediterranean Basin
in the southern of Turkey. In this study, the performance of upstream cofferdam of Berdan Dam during 1980
flood event when the dam was under construction stage, was investigated by using ground measurements and
satellite-based remote sensing data. As a result, flood inundated areas up to the Berdan Dam site in 1980
flood, calculated as 271 hectares by using remote sensing data. It is evaluated that the dam structures built at
the Berdan dam construction site at the 1980 flood event holded the flood flow and contributed flood control
works of downstream areas.
