Actual precipitation index (API) for drought classification
Şen, Zekai; Almazroui, Mansour (Springer International Publishing AG, 2021)The Standard Precipitation Index (SPI) is a widely used statistical technique for the characterization of droughts. It is based on a probabilistic standardization procedure, which converts a Gamma-type probability distribution ... -
Aridity and risk calculations in Saudi Arabian Wadis: Wadi Fatimah case
Şen, Zekai; Al-Harithy, Saad; As-Sefry, Sefry; Almazroui, Mansour (Springer, 2017)Background: Infrequent rainfall and rare flash floods are the primary sources of water in semi-arid and arid regions and are the key aspects in the management of water supply. In these regions, rainfall varies temporally ... -
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 ... -
Climate Change
Şen, Zekai (Springer International Publishing AG, 2020)Climate change and variability are the two prime concerns for future sustainable water, food, energy, agriculture, economy, environment, population, and industry and technology development limitations. -
Climate change expectations in the upper Tigris River basin, Turkey
Şen, Zekai (Springer-Verlag Wien, 2019)This paper studies the Upper Tigris River (UTR) drainage basin in Turkey for climate change impacted runoff estimations. Statistical downscaling method (SDM) is used by taking into consideration spatial dependence function ... -
Climate change impact on rainfall in north-eastern Algeria using innovative trend analyses (ITA)
Boudiaf, Besma; Şen, Zekai; Boutaghane, Hamouda (Springer Science and Business Media Deutschland GmbH, 2021)Climate change impacts affect the hydrological cycle and hence the availability of water resources and their management. Rainfall, the most important hydro-meteorological event and as the main source of water, may have ... -
Climate change impact on water structures
Şen, Zekai (Springer International Publishing AG, 2022)The literature is full of global warming and climate change impact studies on the environment, ecosystem, and different components of hydrological cycle. Unfortunately, these impacts on engineering structure design, ... -
Climate change impacts on sea surface temperature (SST) trend around Turkey seashores
Dabanlı, İsmail; Şişman, Eyüp; Güçlü, Yavuz Selim; Birpınar, Mehmet Emin; Şen, Zekai (Springer International Publishing AG, 2021)This paper focuses on sea surface temperature (SST) trends due to the importance of temperature difference in climate change impact research. These trends are not only essential for climate, but they are also important for ... -
Conceptual monthly trend polygon methodology and climate change assessments
Şen, Zekai (Taylor & Francis Ltd, 2021)Climate change impact search methodologies, for a single hydro-meteorological record, are based mostly on probabilistic, statistical and stochastic processes. The application of these methodologies requires some restrictive ... -
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 ... -
Cumulative Ordinary Kriging interpolation model to forecast radioactive fallout, and its application to Chernobyl and Fukushima assessment: A new method and mini review
Külahcı, Fatih; Şen, Zekai (Springer, 2022)The Cumulative Ordinary Kriging (COK) interpolation method has been proposed for the spatial prediction of atmospheric radioactive fallout in any given region. COK is built on the Ordinary Kriging and Cumulative Semivariogram ... -
Discussion on "Modeling karst spring hydrograph recession based on head drop at sinkholes" by Guangquan, Li, Nico Goldscheider, Malcom S. Field
Şen, Zekai (Elsevier Science Bv, 2018)Groundwater movement model development in karstic aquifers is very difficult due to the complexity of the solution cavities. The authors (Li et al., 2016) have proposed a square law model for expressing the discharge ratio ... -
Discussion “A probability distribution for hydrological drought duration”
Şen, Zekai (Elsevier B.V., 2021)Song et al. (2021) deals with drought duration probabilistic modeling treatment based on Bernoulli-independent and lag-one Mar-kov process modeling procedures. However, calculations are based on percentages, not ... -
Earth systems data processing and visualization using MATLAB introduction
Şen, Zekai (Springer International Publishing AG, 2020)In recent years, there is a tremendous increase in the interaction between art, science, and technology through the unprecedented developments in the computer technology. Almost all aspects of life are directed by computer ... -

Energy innovation
Şen, Zekai (Elsevier Inc., 2018)Renewable energy resources are among the most demanded clean energy alternatives each with temporal and spatial assessment methodologies based on certain equations, algorithms, procedures, logical rules, and generalization. ... -
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 ... -
Flood modeling, prediction and mitigation
Şen, Zekai (Springer International Publishing, 2017)This book draws on the author’s professional experience and expertise in humid and arid regions to familiarize readers with the basic scientific philosophy and methods regarding floods and their impacts on human life and ... -
