    Simulation of the Flood Wave Caused by Hypothetical Failure of the Haditha Dam
    (Taylor & Francis Ltd, 2023) Mhmood, Harith Hamad; Yilmaz, Meric; Sulaiman, Sadeq Oleiwi
    In this research, the flood wave resulting from the hypothetical overtopping failure of the Haditha Dam on the Euphrates River, Iraq, was simulated, utilizing the ArcMap 10.2 and HEC-RAS 5.0.7 software and the observed field data from the Iraqi Ministry of Water Resources. Flooding parameters were calculated, for the study reach from the Haditha Dam to Heet city and major cities in between. The Manning coefficient of the study reach was calibrated to 0.035 and 0.07 for the main river and the floodplain, respectively. The results showed the flood wave propagation along the study reach, the flood hydrograph and time to the peak discharge/time to the maximum water surface elevation, maximum velocity, and width of the inundated area at the selected cities. The analysis outputs and the inundation maps can be used to provide an emergency action plan for the flooded regions.

    Consistency of Spatiotemporal Variability of Modis and Era5-Land Surface Warming Trends Over Complex Topography
    (Springer Heidelberg, 2023) Yilmaz, Meric
    In this study, the trend of widely used MODIS MxD11 and MxD21 Land Surface Temperature (LST) and ERA5-Land Skin Temperature (SKT) and 2 m air temperature products were validated using 2 m air temperature trends obtained by ground observations from 266 stations in 2000-2021 over Turkey, known to have complex topography. The results show that colder regions have substantially higher temporal temperature variability than warmer ones. MxD21 and MxD11 products are 4.4 & DEG;C and 2.9 & DEG;C warmer than ERA5-Land products, respectively, while ERA5-Land products (SKT and 2 m) have nearly similar averages (12.5 & DEG;C). The consistency between MODIS and ERA5-Land data is significantly lower over areas with more complex topography and irrigation activities, despite the fact that the products show a high linear relationship over the study area. While February trends are consistently much higher than other months (2.2 and 1.4 & DEG;C/decade for MODIS and ERA5-Land, respectively), overall MODIS skin temperature products (0.7 & DEG;C/decade) generally exhibit smaller trends than ERA5-Land skin and air temperature trends (0.94 & DEG;C/decade). The results suggested that MODIS and ERA5-Land trends, which are highly consistent with observations, might replace observations in the absence of long-term station-based records.

    Reliability-Based Evaluation of Scouring Around Dual Bridge Piers
    (Croatian Soc Civil Engineers-hsgi, 2019) Yilmaz, Meric; Calamak, Melih; Yanmaz, A. Melih
    The causes of uncertainty involved in temporal variation of the depth of cavern formation due to clear water scouring at dual piers with tandem arrangement are identified in this study. In an example, the probability of failure induced by scouring around dual piers is estimated for various pier spacing using probabilistic analysis. The effects of changes in the coefficient of variation of probabilistic scouring variables and probability distributions on the probability of the loss of stability, are also investigated. It was established that the effects of variations in the coefficient of variation on the probability of the loss of stability are more significant compared to that on the probability distributions of the scour depth.

    Türkiye Üzerinde Era5 Saatlik Hava Sıcaklığı Verilerinin Doğrulanması
    (2022) Yılmaz, Meriç
    Bu çalışmada, Avrupa Orta Vadeli Hava Tahmin Merkezi (ECMWF) tarafından üretilen ERA5 yeniden analiz ürünü saatlik 2 m yüzey hava sıcaklığı verileri, Meteoroloji Genel tarafından işletilen 1773 meteorolojik gözlem istasyonunda elde edilen saatlik sıcaklık verileri kullanılarak 2011 - 2020 yılları arasında Türkiye üzerinde ve 7 coğrafi bölgede doğrulanmıştır. Analizlerde, saatlik, günlük ve aylık ortalama sıcaklık için hata istatistikleri hesaplanmıştır. Sonuçlar, ERA5'in farklı zamansal çözünürlüklerde hava sıcaklıklarını istasyonlardan -0,01 - 0,06 °C sapmayla modellediğini, ortlama mutlak hata ve ortalama hata standart sapmasının ise sırasıyla 3,3 - 4,0 °C ile 1,6 - 3,4 °C olduğunu göstermektedir. Ortalama hata istatistiklerinin gün içinde saatlik ve yıl içinde aylık belirgin bir değişimi olmamakla birlikte, diğer mevsimlere kıyasla kış aylarında hata değişkenliği daha yüksek çıkmaktadır. ERA5 ve istasyon sıcaklık verilerinin korelasyonları çok yüksek çıkmaktadır (0,93 - 0,99). Yüksek zamansal korelasyona karşılık mekansal korelasyonun (0,36) düşüklüğü, ERA5 sıcaklık verisinin farklı bölgelerde güvenilir kullanımından önce mekansal olarak değişken düzeltme katsayılarına ihtiyaç duyacağını ortaya koymaktadır. Ortalama hata istatistikleri, farklı bölgelerde literatürde yapılan doğrulama çalışmalarıyla tutarlıdır. Buna göre, çalışmada elde edilen sonuçlar, ERA5 veri setlerinin Türkiye’de özellikle daha seyrek meteorolojik istasyon ağı içeren bölgelere odaklanan çeşitli uygulamalarda güvenilir bir şekilde kullanılabileceğini önermektedir.

    Accuracy Assessment of Temperature Trends From Era5 and Era5-Land
    (Elsevier, 2023) Yilmaz, Meric
    Many environmental processes and ecological systems are being affected by the warming temperatures as a result of climate change. To correctly identify and attribute the uncertainty estimates in these systems, an investigation of tem-perature trend signal existing in the datasets that are used to study such systems is necessary. In this study, the trend of widely used ERA5 and ERA5-Land temperature estimates between 1951 and 2020 were validated using temperature trends from ground station-based observations in Turkey. The investigation included datasets obtained over 540 stations, and the seasonality and spatio-temporal variability of the trend accuracy was also investigated. On average, the trends of observations over all stations were 0.82 degrees C/decade and 0.30 degrees C/decade for the periods 2001-2020 and 1951-2020, respectively, indicating strong evidence of climate change. When the model datasets used spatially and temporally continuous datasets, the trends identified were 0.91 degrees C/decade and 0.21 degrees C/decade over the entire Turkey for the years 2001-2020 and 1951-2020, respectively. The difference in the 70-year trends of the two esti-mates was attributed to the missing datasets in observations. The differences between the trends of model estimates and observations were higher for the first decade than for the last two decades, stressing the impact of improved model estimates over time. All products showed heavy seasonality, suggesting that winter trends (1.3 degrees C/decade on average) are much higher than the summer (0.3 degrees C/decade) between 2001 and 2020. The results indicated a high degree of consistency between the trends of ERA5/ERA5-Land and observations, implying they may be used as a replacement to observations.
