In this study, the water content that is allocated for agricultural productions wasanalyzed using stochastic dynamic programming. The technical coefficients used in thestudy referred to the agricultural years, ...

Water is the main demand of people settled in the arid areas of large watersheds.This demand is more necessary and critical in the areas with the potential of dustsources and fine sediments entering into the ...

The main objective of the current study was to estimate the demand function forwater in the industrial sector of Zahedan city based on the methodology of dualitypremise. To this end, the trans-log cost function ...

Due to the limited water resources in arid and semi-arid areas, it is necessary toutilize new high-efficiency irrigation systems to irrigate the horticultural crops. Thepresent study attempted to compare the ...

Evapotranspiration is the most important part of the hydrological cycle, which playsa key role in water resource management, crop yield simulation, and irrigationscheduling. Therefore, developing a cost-effective ...

In arid and semi-arid regions of Iran as the rainfall is reduced and the population and the demand for food continue to grow, high-quality water consumption and the development of planting area increasingly gain importance. ...

Scour simulation is a way to prevent a bridge against the possible major damages.  In this study, local scouring around a cylindrical pier in non-cohesive bed sediment was simulated with the aid of Flow-3D model capabilities. ...

Throughout the year, a huge volume of the surface running water as well as sewage flow down into the plantations of the south of Tehran which can have detrimental hygienic and environmental impacts. In this study, people's ...

The evolution of oil spilled in marine environments is affected by its spread, evaporation, emulsion, dissolution and dispersion in the water column. Although it has an environmental impact on marine ecosystems and affects ...

The goal of this study is evaluating the accuracy of geostatistical techniques in map zoning of the salinity of groundwater resources using 40 piezometric wells of Minab plain in the south coasts of Iran. The geostatistical ...

In the development process of the countries, the wetlands play a significant role in people's well-being by providing the goods and services that are used directly and indirectly. Some examples of these goods include ...

Stable modelling in water resources management, on one hand, requires recognizing the relations between the different applications of water and their long-term results and on the other hand taking into account the current ...

Waste recycling is one of the favorable methods in waste management. Since huge amount of hazardous and non-hazardous wastes are produced in petrochemical industry, it is essential to characterize generated wastes and ...

The relationship between the accumulation of nitrate in the soil and its concentration in groundwater and in various plant systems is still not fully understood, but it indicates a high correlation between nitrate leaching ...

There are many cases in open channel flows where the steady flow of water passes through a cluster of vertical cylinders. As a fluid flow is encountered with several obstacles, an overlapping of opposite forces is resulted ...

Tehran generates 7000 tons of municipal solid waste (MSW) daily with 70% of organic component which causes leachate and greenhouse gases generation. Anaerobic digestion (AD), as a natural process, can be a solution. On ...

Water consumption has increased in urban areas, so it is important to calculate its tariff. In Iran, Increasing Block Tariffs (IBT) is used to calculate the water tariff. The first disadvantage of this approach is that ...

It is crucial for environmental planning, land management, and sustainable development to be aware of the quantitative and qualitative characteristics of land changes. The use of vegetation maps is one of the important ...

This study aims to evaluate Spatio-temporal distribution of rainfall through cluster analysis based on Tropical Rainfall Measuring Mission (TRMM) in Iran. To this purpose, the daily-gridded rainfall data were derived for ...

Supply and demand management of Hirmand water resources is one of the most important problems faced by policymakers and they will not be able to manage this sector properly without specifying the future prospects of the ...
