Volume 34, Issue 2 , May and June 2020, , Pages 333-347

https://doi.org/10.22067/jsw.v34i2.81812

Abstract
    Introduction: The erosion, sediment transport, and estimation problems in the streamflow are the most complicated and essential subjects in the river engineering studies. It is important to model and predict these parameters correctly to determine the effective life of the hydraulic structures ...  Read More

Application of Archimedean and Extreme values Copula Functions for Multivariate Analysis of Low Flows in Dez Basin

F. Ahmadi; F. Radmanesh; G. A. Parham; R. Mirabbasi Najaf Abadi

Volume 31, Issue 4 , September and October 2018, , Pages 1031-1045

https://doi.org/10.22067/jsw.v31i4.58373

Abstract
  Introduction: Hydrological phenomena are often multidimensional and very complex. Hence, the joint modeling of two or more random variables is required to investigate the probabilistic behavior of them. To this aim, the copulas can be efficiently utilized to derive multivariate distributions. In addition, ...  Read More

Temperature Trend Analysis by Considering the Hurst Coefficient (Case Study: West Azarbayjan Province)

Farshad Ahmadi; Mohammad Nazeri Tahroudi; Rasoul Mirabbasi Najaf Abadi

Volume 31, Issue 3 , July and August 2018, , Pages 985-1000

https://doi.org/10.22067/jsw.v31i2.56035

Abstract
  Introduction: Climate change in the current century is an important environmental challenge facing the world. Increase in atmospheric concentration of greenhouse gases such as CO2 as a result of human activities has caused a change in a number of hydroclimatic parameters. Climate change and global warming ...  Read More
