The Impact of Breakpoints in Rainfall Time Series on Drought Characteristics Changes (Case Study: Tabriz and Arak Stations, Iran)

M. Gaznavi; A. Mosaedi; M. Ghabaei Sough

Volume 35, Issue 3 , July and August 2021, , Pages 409-425

https://doi.org/10.22067/jsw.2021.14899.0

Abstract
  Introduction: Drought is a climatic phenomenon and an integral part of climate fluctuations that occurs periodically and intermittently throughout the world and across all climates. However, the magnitude of this natural hazard in arid and semi-arid regions, such as most parts of Iran, is more acute ...  Read More

Assessment of Sprinkler Irrigation Systems Situation Using Analytical Hierarchy Process Method (Case Study: Zanjan Plain)

P. Moradzadeh; H. Ojaghlou; Mohammad Ghabaei Sough

Volume 33, Issue 4 , September and October 2019, , Pages 565-578

https://doi.org/10.22067/jsw.v0i0.81485

Abstract
    Introduction: The average of irrigation efficiency is less than the global average due to improper irrigation systems and traditional water management practices in the field. The use of modern irrigation systems is one of the most important ways to cope with the water shortage crisis in Iran. ...  Read More

Assessment of Humidity Conditions and Trends Based on Standardized Precipitation Evapotranspiration Index (SEPI) Over Different Climatic Regions of Iran

Mohammad Ghabaei S; Hamid Zare Abyaneh; Abolfazl Mosaedi; S. Zahra Samadi

Volume 30, Issue 5 , November and December 2016, , Pages 1700-1717

https://doi.org/10.22067/jsw.v0i0.47565

Abstract
  Introduction: Drought is a recurrent feature of climate that caused by deficiency of precipitation over time. Due to the rise in water demand and alarming climate change, recent year’s observer much focus on drought and drought conditions. A multiple types of deficits and relevant temporal scales can ...  Read More

Modeling Rain-fed Wheat and Barley based on Meteorological Features and Drought Indices

A. Mosaedi; S. Mohammadi Moghaddam; M. Ghabaei Sough

Volume 29, Issue 3 , July and August 2015, , Pages 730-749

https://doi.org/10.22067/jsw.v0i0.36894

Abstract
  Introduction: Weather features and their variations have an important role in the yield of agricultural products, especially in rain-fed conditions. The main metrological variables that affected yields consist of precipitation, temperature, soil moisture and solar radiation. Also, drought is one of the ...  Read More

Drought Monitoring Based on Standardized Precipitation Evaoptranspiration Index (SPEI) Under the Effect of Climate Change

H. Zareabyaneh; M. GHobaeisoogh; Abolfazl Mosaedi

Volume 29, Issue 2 , May and June 2015, , Pages 374-392

https://doi.org/10.22067/jsw.v0i0.36472

Abstract
  Introduction: Drought is a natural and recurrent feature of climate. The characterizations of it may change under the effect of climate change in future periods. During the last few decades a number of different indices have been developed to quantify drought probabilities. Droughts are caused by disruptions ...  Read More

Modification of Standardized Precipitation Index (SPI) Based on Relevant Probability Distribution Function

A. Mosaedi; M. Ghabaei Sough

Volume 25, Issue 5 , November and December 2011

https://doi.org/10.22067/jsw.v0i--.11258

Abstract
  Abstract SPI is based on fitting a gamma distribution to precipitation amounts in selected periods. Based on current research, the gamma distribution may not be fitted to annual precipitation of some regions. In order to evaluate this subject, annual precipitation have been used during 1958- 2007 at ...  Read More

Evaluation Effect of Input Parameters Preprocessing in Artificial Neural Networks (Anns) by Using Stepwise Regression and Gamma Test Techniques for Fast Estimation of Daily Evapotranspiration

M. Ghabaei Sough; A. Mosaedi; M. Hesam; A. Hezarjaribi

Volume 24, Issue 3 , July and August 2010

https://doi.org/10.22067/jsw.v0i0.3631

Abstract
  Abstract Process of evapotranspiration (ETo) is a major component of the hydrologic cycle that its accurate estimation plays an important role to achieve sustainable development in water balance, irrigation system design and planning and management of water resources. Being a function of different metrological ...  Read More
