This paper presents the development process and key findings of the first-ever health impact assessment (HIA) conducted on the proposed Alpu coal-fired power plant (ACPP) in Eskisehir, Turkiye. The study followed a systematic HIA methodology, commencing with an extensive literature search on coal-fired power plants and the region's specific characteristics during the screening step. In the subsequent scoping phase, in-depth discussions were conducted with a diverse range of experts and stakeholders to be used as inputs. The study findings highlight that the ACPP's impact on human health will be multifaceted. In addition to the estimated additional 10,000 premature deaths attributed to air pollution during the 35-year, the ACPP is expected to have implications for occupational health, including increased occupational diseases and injuries. Furthermore, it may also affect income, employment, food access, and nutritional quality. The health implications of the ACPP will extend beyond Eskisehir, potentially affecting a region with a current population of approximately 11 million residents throughout its lifetime.

This study was undertaken to evaluate how future uncertain climate-related hydrological responses and low and highflow frequencies affect local hydrology up to the 2100, depending on different Global Circulation Models (GCM) and different Concentration Scenarios (CS). To this end, daily total precipitation and daily mean temperature data were used for RCP4.5 and RCP8.5 CSs by employing GCMs (GFDL-ESM2M, HadGEM2-ES and MPI-ESM-MR). In the study, the years 1971–2000 were chosen as the baseline period. Future streamflow predictions were modeled by machine learning. The models were calibrated with baseline period data and future streamflow values were predicted by using the best Streamflow Prediction Model during the 2055s (2041–2070) and 2085s (2071–2100) periods. Flow Duration Curves from the streamflow predictions were obtained and by using them, discharges corresponding to 95% probability of exceedance for lowflow and 5% probability of exceedance for highflow were calculated. According to the findings, it is predicted that there will be decrease of approximately 21% in lowflow discharges and approximately 30% in highflow discharges. This prediction has suggested water resources managers to implement mitigation measures to climate change in Eastern Black Sea Basin and most probably in Türkiye, especially in the context of continuity of aquatic life and sustainable water supply. It is expected that the paper will take a very important place in estimating and evaluating the expected changes in basin hydrology in the coming years, especially in the highflows and lowflows, which are the key concepts in hydroelectric power generation and in flood management. • Development of streamflow prediction model for climatic projection data. • Streamflow estimation using limited input data in small catchment. • Obtaining far future streamflow for water resources pre-planning. • Discussion of the impact of climate change on daily streamflow extremes.
