    Paleoenvironment of geomorphic surfaces of an alluvial fan in the eastern Isfahan, Iran, in the light of micromorphology and clay mineralogy 

    نوع: Journal Paper
    نویسنده : Omid Bayat; Hamidreza Karimzadeh; علیرضا کریمی; Mostafa Karimian Eghbal; Hossein Khademi; Alireza Karimi
    سال: 2017
    خلاصه:

    indicated that the illuviation process in the calcareous soils of the arid regions of the eastern Isfahan was probably in response to Quaternary moist conditions. There was no significant difference between clay coating properties of the studied relict...

    Spatiotemporal reference evapotranspiration changes in humid and semi-arid regions of Iran: past trends and future projections 

    نوع: Journal Paper
    نویسنده : M. Nouri; M. Homayee; محمد بنایان اول; M. Nouri; M. Homayee; Mohammad Bannayan Aval
    سال: 2017
    خلاصه:

    in 1966–2010. The ET0 changes were attributed to wind speed changes in semi-arid regions and mean tempera- ture changes in humid areas in the past period. An increase in ET0 was projected under all scenarios due mainly to temper- ature rise and declined...

    Effects of Land use on the Structural Diversity of Soil Bacterial Communities in South Eastern Iran 

    نوع: Journal Paper

    analysis of the denaturing gradient gel electrophoresis (DGGE) of the polymerase chain

    reaction (PCR) amplified 16S rDNA fingerprints...

    Developing a CFD-based Approach to Estimate Evaporation from Water Surfaces in (Semi-) Arid Regions 

    نوع: Conference Paper
    نویسنده : علی عباسی; Frank Annor; Nick van de Giesen; Ali Abbasi; Frank Annor; Nick van de Giesen
    سال: 2015
    خلاصه:

    In arid and semi-arid regions where evaporation highly exceeds rainfall, approximately one half of the stored water in shallow lakes may be lost due to evaporation. Precisely estimating this for very shallow lakes is however a daunting tasks due...

    Magnetic susceptibility and morphological characteristics of a loess-paleosol sequence in northeastern Iran 

    نوع: Journal Paper
    نویسنده : علیرضا کریمی; Hossein Khademi; Shamsollah Ayoubi; Alireza Karimi
    سال: 2013
    خلاصه:

    of this study show the effectiveness of magnetic susceptibility properties for the interpretation of paleopedological and paleoenvironmental conditions of loess-paleosol sequence in northeastern Iran. It should be noted that in the arid regions, to avoid...

    Modeling daily stream flow using plant evapotranspiration method 

    نوع: Journal Paper
    نویسنده : Milad Jajarmizadeh; Sobri Harun; بیژن قهرمان; M. H. Mokhtari; Bijan Ghahraman
    سال: 2012
    خلاصه:

    In hydrological models, soil conservation services (SCS) are one of the most widely used procedures to

    calculate the curve number (CN) in rainfall run-off simulation. Recently, another new CN accounting

    procedure ...

    The Impact of Land use on Bacterial Community Composition and Physicochemical Properties of Soil 

    نوع: Journal Paper
    نویسنده : قباد جلالی; امیر لکزیان; علیرضا آستارائی; علی اکبر حداد مشهد ریزه; M. Azadvar; E. Esfandiarpour; ghobad jalali; Amir Lakzian; Ali Reza Astaraei; Aliakbar Haddad-Mashadrizeh
    سال: 2016
    خلاصه:

    In order to determine the effects of land use on bacterial community composition

    and some physicochemical properties of soil, a study was carried out in three different

    land uses (orchard, farm and shrub) in arid-region soils located...

    A framework to simulate small shallow inland water bodies in semi-arid regions 

    نوع: Journal Paper
    نویسنده : علی عباسی; F. Ohene Annor; N. van de Giesen; Ali Abbasi
    سال: 2017
    خلاصه:

    In this study, a framework for simulating the flow field and heat transfer processes in small shallow inland water bodies has been developed. As the dynamics and thermal structure of these water bodies are crucial in ...

    Calcic soils as indicators of profound Quaternary climate change in eastern Isfahan, Iran 

    نوع: Journal Paper
    نویسنده : Omid Bayat; Hamidreza Karimzadeh; Mostafa Karimian Eghbal; علیرضا کریمی; Ronald Amundson; Alireza Karimi
    سال: 2018
    خلاصه:

    In the high plateau region of central Iran, there is both a lack of information on calcic soil processes and aspects of Quaternary paleoclimate. Thus, the research discussed here was undertaken as afirst step to assess the ...
