assessment of wind erosion intensity by irifr. e.a model (case study: abuzeidabad, kashan)

a study on insurer solvency by panel data model: the case of iranian insurance market

the aim of this thesis is an approach for assessing insurer’s solvency for iranian insurance companies. we use of economic data with both time series and cross-sectional variation, thus by using the panel data model will survey the insurer solvency.

The Effect of Intensity and Duration of Drought on Wind Conditions and Wind Erosion in Agricultural Areas (Case Study: Damghan Area)

Wind erosion is one of the natural disasters in the arid regions of central Iran is increasingly faced by mismanagement of natural resources in the rise of this phenomenon has had a large impact. Precipitation, temperature and wind are the most important climatic factors that affect this phenomenon. Lack of rainfall, temperature increased and wind speed increased evapotranspiration in the regio...

Efficiency Assessment of Rangeland Hydrology and Erosion Model (RHEM) for water erosion quantification (Case Study: Sangane Watershed-Iran)

Assessment of Wind Erosion Parameters Using Wind Tunnels

*Lawrence J. Hagen, USDA-ARS, Wind Erosion Research Unit, Throckmorton Hall 2004, Kansas State University, Manhattan, KS 66506. *Corresponding author: [email protected]. Contribution from USDA-ARS in cooperation with Kansas Agric. Exp. Sta., Contribution No. 99-389-A. ABSTRACT Assessment of wind erosion parameters applicable to the field scale using wind tunnels requires attention to both scal...

Gully Erosion Susceptibility Assessment using Multivariate Regression Model (Case Study: Kiasar, Southern Mazandaran Province)

Gully erosion when it comes to positive processes in the most severe operating conditions and the most favorable conditions for the performance of other words is a positive process. One of the most important issues discussed gully erosion monitoring and evaluation of benchmarking is to extract and identify the type of erosion. In this paper the groove factor and drainage ditches, and selected a...

برآورد و ارزیابی فرسایش بادی با به‌کارگیری شبکه‌ باور بیزی (BBNs) در دشت سگزی اصفهان

Soil erosion by wind is a widespread problem in the arid lands of Iran. This research estimated and assessed the severity of wind erosion in Segzi desertification hotspot located in the eastern part of Isfahan township, focusing on criteria used in the IRIRF (Iranian Research Institute of Forest and Rangelands) model. Bayesian belief networks (BBNs) were also used to convert the IRIFR model to ...
