Description :
The impacts of dam, levee, and bridge constructions, sand-gravel mining activities and water withdrawals during the industrialization period of the Sakarya River Basin have been explored by analyzing flow, sediment and channel cross section data from different periods in time by comparing pre- and post- 1975 periods. Assessment of data shows that average annual flow is reduced by almost 20% after 1975 and that flow became less variable. This research clearly undermines how human activities can alter the river hydrology and morphology.
