—Technological advances which accelerated after the industrial revolution, extensive fossil fuel usage, land use changes and emissions of greenhouse gases from various sources contribute to global warming and consequently climate change. Climate change affects hydrological and ecological processes significantly. In this study, effects of impervious areas of Eskişehir, a city in the Porsuk Stream Watershed in Western Inner Anatolia of Turkey, to the Porsuk Stream pollution between 1975 and 2010 have been studied. For the determination of these effects the HSPF model (Hydrological Simulation Program-Fortran) developed by United States Environment Protection Agency-EPA has been used. Since sediment concentration is very important to investigate the modeling, behavior sediment has been modeled. In the impervious land segments, sediment concentration is high and so impervious land segments have been found to be affecting sediment parameter concentrations meaningfully. The parameter values have been set to their extreme values to investigate the resulting effects on the concentrations. It has been determined that the maximum sediment concentration in outflow becomes 570 mg/L in the Porsuk Stream based on monthly averages respectively. In addition, with using climate scenario A1 simulated until 2100, sediment concentration is increasing significantly. By this way, urban centers effects on watershed hydrology and water quality in response to climate change have been investigated.
