Evaluating the performance of a WRF initial and physics ensemble over Eastern Black Sea and Mediterranean regions in Turkey
Düzenli, Eren; Yücel, İsmail; Pilatin, Heves; Yılmaz, Mustafa Tuğrul (Elsevier BV, 2021-01-15)
The physics- and initial-based ensemble approach for Weather Research and Forecasting (WRF) model is applied for predicting four different extreme precipitation events that occurred in summer and autumn over the two most f...
Nonstationarity impacts on frequency analysis of yearly and seasonal extreme temperature in Turkey
Aziz, Rizwan; Yücel, İsmail; Yozgatlıgil, Ceylan (Elsevier BV, 2020-07-01)
This study investigates the temporal variability in yearly and seasonal extreme temperatures across Turkey using stationary and nonstationary frequency analysis. The analyses are conducted using Generalized Extreme Value (...
Performance evaluation of satellite- and model-based precipitation products over varying climate and complex topography
Amjad, Muhammad; Yılmaz, Mustafa Tuğrul; Yücel, İsmail; Yılmaz, Koray Kamil (Elsevier BV, 2020-05-01)
Accuracy assessment of precipitation retrievals is a pre-requisite for many hydrological studies as it helps to understand the source and the magnitude of the uncertainty in hydrological response variables, particularly ov...
Investigating the Effect of Climate Change on Stormwater Networks: Capital Ankara Case
Oruç, Sertaç; Yücel, İsmail; Yılmaz, Ayşen (2020-01-01)
In this study, we applied the analysis results of past and future variations of extreme precipitation and land use/cover changes in Ankara province for a newly built stormwater network of a pilot study area in Etimesgut,...
Evaluation of Remotely-Sensed and Model-Based Soil Moisture Products According to Different Soil Type, Vegetation Cover and Climate Regime Using Station-Based Observations over Turkey
Bulut, Burak; Yılmaz, Mustafa Tuğrul; Afshar, Mehdi H.; Sorman, A. Unal; Yücel, İsmail; Cosh, Michael H.; Simsek, Osman (MDPI AG, 2019-08-01)
This study evaluates the performance of widely-used remotely sensed- and model-based soil moisture products, including: The Advanced Scatterometer (ASCAT), the Advanced Microwave Scanning Radiometer-Earth Observing System ...
Assessing different sources of uncertainty in hydrological projections of high and low flows: case study for Omerli Basin, Istanbul, Turkey
Engin, Batuhan Eren; Yücel, İsmail; Yılmaz, Ayşen (2017-07-01)
This study investigates the assessment of uncertainty contribution in projected changes of high and low flows from parameterization of a hydrological model and inputs of ensemble regional climate models (RCM). An ensemble ...
Inter-comparison of statistical downscaling methods for projection of extreme flow indices across Europe
Hundecha, Yeshewatesfa; Sunyer, Maria A.; Lawrence, Deborah; Madsen, Henrik; Willems, Patrick; Buerger, Gerd; Kriauciuniene, Jurate; Loukas, Athanasios; Martinkova, Marta; Osuch, Marzena; Vasiliades, Lampros; Von Christierson, Birgitte; Vormoor, Klaus; Yücel, İsmail (2016-10-01)
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 dif...
Climate change impacts on extreme precipitation of water supply area in Istanbul: use of ensemble climate modelling and geo-statistical downscaling
Kara, Fatih; Yücel, İsmail; Akyürek, Sevda Zuhal (2016-01-01)
Numerous statistical downscaling models have been applied to impact studies, but none clearly recommended the most appropriate one for a particular application. This study uses the geographically weighted regression (GWR) ...
Assessment of a flash flood event using different precipitation datasets
Yücel, İsmail (2015-12-01)
Remotely sensed precipitation estimates and regional atmospheric model precipitation forecasts provide rainfall data at high spatial and temporal resolutions and can therefore be potentially used for hydrological applicati...
Climate change effects on extreme flows of water supply area in Istanbul: utility of regional climate models and downscaling method
Kara, Fatih; Yücel, İsmail (2015-09-01)
This study investigates the climate change impact on the changes of mean and extreme flows under current and future climate conditions in the Omerli Basin of Istanbul, Turkey. The 15 regional climate model output from the ...
