Abstract
The aim of this study was to determine changes in surface area and volume of the Altinapa
Reservoir, in Turkey, according to the water levels. To adopt measures for collecting more water in dam
reservoirs, lakes and ponds, to prevent water pollution, protect water sources and extend the service life of
these facilities, it is important for users (Municipalities, SHW, Irrigation Unions etc.) to know the current
topographic conditions and any changes in the storage capacities of these facilities. Sedimentation is one
of the most serious factors that threaten aquatic environments such as dams, lakes and ponds.
Sedimentation causes some lakes, ponds and dams to be filled and polluted in a short time. It also causes
loss of capacity and reduces the lifespan of the facilities.
Changes in surface area and volume of the Altinapa Reservoir were identified by comparison of
topographic and bathymetric data used for the management of the facility. Two ArcGIS digital elevation
models, from 2009 and 1981, were used to determine changes in storage capacity of the reservoir. The
calculations indicated that, within this 28-year period, the storage capacity of the reservoir decreased by
12.4% due to sedimentation. Furthermore, compared to volume data from 1967, when the dam was
constructed, the water storage capacity was found to have decreased by 33.4%.
