Classical and innovative-Şen trend assessment under climate change perspective
Dabanlı, İsmail; Şen, Zekai (Inderscience Publishers, 2018)The main purpose of this paper is to provide a comparison between the innovative-Şen and classical trend methods. Additionally, significance levels at ±5% and ±10% levels are suggested for the first time on the innovative-Şen ... -
Crossing empirical trend analysis (CETA) at risk levels in hydro-meteorological time series
Şen, Zekai (Springer Wien, 2022)Trend identification procedures are used to identify systematic monotonic trendlines in a given hydro-meteorological time series recording to represent time-dependent variations as increases or decreases. Different ... -
Extreme value innovative trend analysis methodology
Şen, Zekai (Inderscience Enterprises Limited, 2022)The main concern of the article is to determine the trend analyses of upper and lower extreme values separately, apart from the classical central trend. The innovative trend analysis (ITA) modification is adapted for extreme ... -
Flash flood risk and climate analysis in the extreme south of algeria (the case of in-guezzam city)
Zegait, Rachid; Şen, Zekai; Pulido-Bosch, Antonio; Madi, Housseyn; Hamadeha, Bachir (AGH University of Science and Technology Press, 2022)Natural risks, particularly flood risk, are a topical subject in Algeria and throughout the world, particularly given the last major catastrophic floods in Sudan (2020) and North Africa. With the development of the climate ... -
General modeling of karst spring hydrographs and development of a dimensionless karstic hydrograph concept
Şen, Zekai (Springer, 2020)The response of a karstic-aquifer solution-cavity network subjected to a rainfall event leads to a hydrograph with rapidly increasing rising limb, but comparatively slower recession limb. In published studies, initial ... -
Hydroelectric energy potential classification via hypsographical curve concept
Şen, Zekai (Wiley, 2022)Human activities are directly related to fossil fuel consumption and cause global warming and climate change effects by emitting greenhouse gas into the lower atmosphere. To reduce and adapt to such effects, renewable ... -
Long-term spatio-temporal drought variability in Turkey
Dabanlı, İsmail; Mishra, Ashok K.; Şen, Zekai (Elsevier Science Bv, 2017)The spatio-temporal variability of drought is presented by evaluating homogeneously distributed 250 station records from 1931 to 2010 for 80 years' duration in Turkey. The drought analysis is implemented using Standardized ... -
Mitigation of time series approach on climate change adaptation on rainfall of Wadi Al-Aqiq, Madinah, Saudi Arabia
Rahman, Norhan Abdul; Yusop, Zulkifli; Şen, Zekai; Taher, Saud; Kane, Ibrahim Lawal (Penerbit UTM Press, 2017)Rainfall record plays a significant role in assessment of climate change, water resource planning and management. In arid region, studies on rainfall are rather scarce due to intricacy and constraint of the available data. ... -
A new innovative method for model efficiency performance
Şen, Zekai; Şişman, Eyüp; Kızılöz, Burak (IWA Publishing, 2022)In every aspect of scientific research, model predictions need calibration and validation as their representativity of the record measurement. In the literature, there are a myriad of formulations, empirical expressions, ... -
Physical and practical hydrograph recession modeling in karstic sinkholes
Şen, Zekai; Dabanlı, İsmail; Şişman, Eyüp (IWA Publishing, 2020)Karstic spring discharge is related to the hydraulic head recession through a power function with an exponent <1. In the literature, analytical solutions are available for exponential and non-exponential models based on a ... -
Temperature and precipitation risk assessment under climate change effect in northeast algeria
Boudiaf, Besma; Dabanlı, İsmail; Boutaghane, Hamouda; Şen, Zekai (Springer International Publishing AG, 2020)Climate change impacts on social, economic, industrial, agricultural, and water resource systems tend to increase incrementally with each passing day. Therefore, it is necessary to plan to control its effects, especially ... -
Wet and dry period identification method through serial correlation decomposition
Şen, Zekai (Taylor & Francis Ltd, 2022)The serial correlation coefficient is the linear dependence procedure used most frequently to identify the short-memory dependence in a given hydrometeorology time series. The serial correlation formulation can be decomposed ... -
Wet and dry spell feature charts for practical uses
Şen, Zekai; Şişman, Eyüp; Dabanlı, İsmail (Springer, 2020)Water resources management is dependent on wet and dry spells occurrences in an alternative manner. Therefore, information about their probabilistic occurrence frequencies and statistical parameters are the most required ...
