The strength and ductility of concrete improve under multi-axial compressive stress due to confinement effect. Some parameters are effective for considering the confinement in concrete and various stress-strain models were developed by different researchers. Longitudinal and transverse reinforcement steels can influence on confinement in reinforced concrete members. In this paper, various stres...

Potential evapotranspiration (PET) is crucial for water resources assessment. In this regard, the FAO (Food and Agriculture Organization)–Penman–Monteith method (PM) is commonly recognized as a standard method for PET estimation. However, due to requirement of detailed meteorological data, the application of PM is often constrained in many regions. Under such circumstances, an alternative metho...

Estimated daily reference crop evapotranspiration (ETo) is normally used to determine the water requirement of crops using the crop factor method. Many ETo estimation methods have been developed for different types of climatic data, and the accuracy of these methods varies with climatic conditions. In this study, pair−wise comparisons were made between daily ETo estimated from eight different E...

Accurate estimation of reference evapotranspiration is essential for agricultural management and water resources engineering applications. In the present study, ability precision three artificial intelligence (AI) models (i.e., Support Vector Machines (SVMs), Adaptive Neuro-Fuzzy Inference System (ANFIS) Categorical Boosting (CatBoost)) were assessed estimating daily (ET0) using limited weather...

iran was located in the arid belt and desert region of the world. this climatic situation was presented in several parts of iran such as qazvin. evapotranspiration is one the most important parameter which was effect on agricultural development. there are different methods for estimating this item which selected by climatic conditions. this research concentrates to evaluate 28 empirical and com...

This study aims at assessing the accuracy of estimating daily reference evapotranspiration (ETo) computed with NASA POWER reanalysis products. Daily ETo estimated from local observations weather variables in 14 stations distributed across Alentejo Region, Southern Portugal were compared derived data, using raw and bias-corrected datasets. Three different methods used to compute ETo: (a) FAO Pen...

This paper investigates the abilities of Artificial Neural Networks (ANN), Least Squares – Support Vector Regression (LS-SVR), Fuzzy Logic, and Adaptive Neuro-Fuzzy Inference System (ANFIS) techniques to improve the accuracy of daily pan evaporation estimation in sub-tropical climates. Meteorological data from the Karso watershed in India (consisting of 3801 daily records from the year 2000 to ...
