Streamflow drought index (SDI) is based on the assumption that the data series of streamflow follows the Gamma distribution. This note investigated the efficiency of 65 different probability distributions in fitting the monthly and annual discharge data series of selected hydrometric stations in Iranian basins. Accordingly, Wakeby, Johnson SB, and...

In this research, a number of paired three-dimensional Atmosphere-Ocean General Circulation Models (AOGCM) from CMIP (Climate Model Inter Comparison Project) 5 group with the base period of 1989–2005 have been evaluated and the output of these models was micro-scaled and calibrated by LARS-WG software. The appropriate model was selected to simulate...
Article
Full-text available
In recent decades, climate change has caused an increase in anomalies in climatic variables and endangered critical infrastructures such as water resources. This change is of paramount importance for southern Iran, especially in the low-precipitation Sistan Plain. Therefore, it is crucial to consider variations in evaporation in the past and the tr...

This research has investigated the simulation of sustainable water resources management to assess the impact of socio-economic development on water, food and energy resources security in Khuzestan Province in Iran. To achieve this goal, after simulation of the water-food-energy system dynamics model, taking into account results of the sensitivity a...
Article
Full-text available
By technology development and industrialization of human societies, we have seen an increase in greenhouse gases produced in the earth that causes the occurrence of climate change. By disturbing the balance in different parts of the earth we have seen negative results like a flood, drought, etc., so based on the importance that climate change has o...
Article
en In the present research the aim was to prepare a spatial and temporal optimization model for allocating irrigation water and cropping pattern in the Maroon irrigation and drainage networks, which are located in the province of Khoozestan, under uncertainty. Hydrometrical data were gathered from the Maroon network station. Meteorological data wer...

The plant response of salinity and drought stresses and the role of them to reduce water absorption are expressed by several mathematical models. The reduction functions are classified additive, multiplicative and conceptual models. In this study six different macroscopic reduction functions, using data from greenhouse tomatoes, were evaluated: Van...
