Paleoenvironment of geomorphic surfaces of an alluvial fan in the eastern Isfahan, Iran, in the light of micromorphology and clay mineralogy
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
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
and shrub
land) in arid-region soils located in southeast of Iran using molecular biology-based. The
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
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
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
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
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
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
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 ...
Investigation of Temperature Dynamics in Small and Shallow Reservoirs, Case Study: Lake Binaba, Upper East Region of Ghana
An unsteady fully three-dimensional model of Lake Binaba (a shallow small reservoir) in semi-arid Upper East Region of Ghana has been developed to simulate its temperature dynamics. The model developed is built on the ...
