Impact of Climate Change in the Southern Mediterranean of Turkey: A method to assess Oymapinar reservoir’s inflow projections

Mesta Yoleri, Buket
Assessment of trends in climatological parameters observed in the last decades and the climate change projections through modeling studies indicated a high potential of increasing temperatures, decreasing precipitation, and runoff for Southern Europe and the Mediterranean basin. Within the scope of this study, climate change analysis for Antalya and its surrounding basins is conducted and the effects of climate change on streamflow in Oymapınar Basin and inflow of Oymapınar HEPP that is used for energy production are investigated. Climate change analyses are carried out using CORDEX Regional Climate Models and MRI’s (Japan Meteorological Research Institute) super high-resolution MRI-AGCM and NHRCM models. Precipitation and temperature projections are carried out using each of these models and also through ensemble analysis. HBV-light and HEC-HMS are used for hydrological modeling of the Oymapınar basin to identify likely impacts on streamflow as well as for short-, medium- and long-term analysis of the Oymapınar HEPP reservoir inflow. Almost all of the climate models used in the study predict a decrease in areal precipitation means in the study area in the medium and long-term, and an increase in temperature for short-, medium- and long-term both for RCP4.5 and RCP8.5 scenarios. It is estimated that climate change effects that are expected to be experienced in temperature and precipitation will reduce the inflows to the Oymapınar HEPP reservoir, especially in the long term. In order to minimize the potential negative impacts of the variations in precipitation and temperature caused by climate change, and their effects on water resources and hydropower production, it seems necessary to develop effective adaptation strategies and start implementing them in a tiered manner.


Future climate change impact assessment of watershed scale hydrologic processes in Peninsular Malaysia by a regional climate model coupled with a physically-based hydrology modelo
Amin, M. Z. M.; Shaaban, A. J.; Ercan, Ali; Ishida, K.; Kavvas, M. L.; Chen, Z. Q.; Jang, S. (2017-01-01)
Impacts of climate change on the hydrologic processes under future climate change conditions were assessed over Muda and Dungunwatersheds of PeninsularMalaysia bymeans of a coupled regional climate and physically- based hydrology model utilizing an ensemble of future climate change projections. An ensemble of 15 different future climate realizations from coarse resolution global climate models' (GCMs) projections for the 21st century was dynamically downscaled to 6 km resolution over Peninsular Malaysia by ...
Identifying impacts of climate change on water resources using CMIP6 simulations: Havran basin case
Çaktu, Yasemin; Yücel, İsmail; Fıstıkoğlu, Okan; Department of Earth System Science (2022-9-2)
This study aims to investigate climate change effect on precipitation, temperature and discharge in Havran basin which has thousands of decares of agricultural lands. Changes in precipitation and temperature were determined using 10 global climate models (GCMs) for total precipitation and 13 GCMs for average temperature from Coupled Model Intercomparison Project Phase 6 (CMIP6) for the historical period, SSP2-4.5 (moderate-case) and SSP5-8.5 (worst-case) scenarios. Both station observations and ERA5-Land re...
Comparing ecological structure of Turkish shallow lakes between the seasons, and wet & dry years
Çağan, Ali Serhan; Beklioğlu, Meryem; Department of Biology (2015)
Due to global climate change, lakes in Mediterranean climate face the problem of reduced precipitation and enhanced evaporation along with increased water abstraction for irrigation that are largely causing changes in water level, salinity and nutrient dynamics. In this study 22 Turkish shallow lakes were investigated in the Mediterranean climate zone. All lakes were sampled with a well-established snapshot sampling protocol. There are 19 lakes, which were sampled once during both spring and summer seasons ...
Changes in precipitation climatology for the Eastern Mediterranean using CORDEX RCMs, NHRCM and MRI-AGCM
Mesta, Buket; Sasaki, Hidetaka; Nakaegawa, Tosiyuki; Kentel Erdoğan, Elçin (2022-07-01)
© 2022Mediterranean Basin is expected to be one of the regions most severely impacted by global climate change. However, the complex interactions of driving forces of climate in the region create a challenge for climate projections for the future. Findings from climate change studies support the inter-model and inter-regional variability of projections on climate change impacts. On the other hand, the studies on the evaluation of the simulation skills of high-resolution climate models for the region particu...

The effect of methods of statistical downscaling of daily precipitation on changes in extreme flow indices under a plausible future climate change scenario was investigated in 11 catchments selected from 9 countries in different parts of Europe. The catchments vary from 67 to 6171 km(2) in size and cover different climate zones. 15 regional climate model outputs and 8 different statistical downscaling methods, which are broadly categorized as change factor and bias correction based methods, were used for th...
