Analyzing the uncertainty of potential evapotranspiration models in drought projections derived for a semi-arid watershed
Okkan, Umut; Fıstıkoğlu, Okan; Ersoy, Zeynep Beril; Noori, Ahmad Tamim (Springer, 2024)Potential evapotranspiration (PET) serves as a proxy for estimating actual evapotranspiration (AET) in hydrological model simulations and constitutes an input for drought analyses. Nonetheless, it is elusive how the inclusion ... -
Dinamik su bütçesi modeline destek vektör regresyonu entegrasyonu
Yağış-akış modelleri kapsamında ele alınan modeller içerisinden kavramsal modeller havza dinamiğini atanan parametreler yardımıyla benzeştirmeye çalışırken, kapalı kutu modelleri ise fiziksel süreci dikkate almadan veri ... -
Embedding machine learning techniques into a conceptual model to improve monthly runoff simulation: A nested hybrid rainfall-runoff modeling
Okkan, Umut; Ersoy, Zeynep Beril; Kumanlıoğlu, Ahmet Ali; Fıstıkoğlu, Okan (Elsevier, 2021)One of the frequently adopted hybridizations within the scope of rainfall-runoff modeling rests on directing various outputs simulated from the conceptual rainfall-runoff (CRR) models to machine learning (ML) tech- niques. ... -
Evaluating climate change effects on runoff by statistical downscaling and hydrological model GR2M
Okkan, Umut; Fıstıkoğlu, Okan (Springer Wien, 2014)The main purpose of this study is to evaluate the impacts of climate change on Izmir-Tahtali freshwater basin, which is located in the Aegean Region of Turkey. For this purpose, a developed strategy involving statistical ... -
Internal structure modification of a simple monthly water balance model via incorporation of a machine learning-based nonlinear routing
Okkan, Umut; Ersoy, Zeynep Beril; Fıstıkoğlu, Okan (IWA Publishing, 2024)Among various monthly water balance models, one of the models that has the simplest structure and offers a well-behaved conceptual platform is the GR2M. Despite the widespread use of the model with two-free parameters, the ... -
Projecting aridity from statistically downscaled and bias-corrected variables for the Gediz Basin, Turkey
Kırdemir, Umut; Okkan, Umut; Fıstıkoğlu, Okan (Iwa Publishing, 2022)Due to climatological changes, a study was conducted in the Gediz Basin, Turkey, where agricultural production holds an important place. In the study prepared, 12 general circulation models (GCMs) were utilized under ...
