Landslides are a widespread natural phenomenon that play an important role in landscape evolution and responsible for several casualties damages. The Abruzzo Region (Central Italy) is largely affected by different types of landslides from mountainous to coastal areas. In particular, the hilly piedmont area characterized active geomorphological processes, mostly represented slope instabilities r...

This work aims to extract the mineralogical constituents of the Lahroud Hyperion scene situated in the NW of Iran. Like the other push-broom sensors, Hyperion images suffer from spectral distortions, namely the smile effect. The corresponding spectral curvature is defined as an across-track wavelength shift from the nominal central wavelength, and alters the pixel spectra. The common “column me...

conclusions hospital managers need to discover better ways to promote safety and health programs for their staff according to nurses’ area of work and their type of units. they should also encourage greater levels of participation in safety-enhancing initiatives in the hospital’s ethical climate, especially in the areas of nurses’ perceptions of their physician colleagues, and for nurses with a...

The aim of this paper is to project extreme precipitation events in an arid and a semiarid station. In order to project climate change based on general circulation models (GCMs), we have applied LARS-WG[1] downscaling tool. This stochastic weather generator down-scaled the climate of two synoptic stations using HADCM3 model and A2 emission scenario for 2040. We extracted extreme precipitation e...

desertification is the consequence of series of processes in which climate change and human activities are more important factors than others. arid and semi-arid areas have occupied most parts of iran. sistan region is one of arid areas of iran where wind erosion is an important factor of land degradation and soil deterioration. for classification of desertification intensity, several methods h...

Abstract Intensification of extreme rainfall-runo events in arid and semi-arid regions because climate change induce the water erosion that contributes considerably to loss vegetal layers soils reduce storage capacity dams by silting transported sediments from watershed impoundment. This paper aims at proposing means for protecting Mghila dam against identification delimitation vulnerable areas...

Paleoclimate was reconstructed by the clay mineral assemblages of shale units of Pabdeh (PaleoceneOligocene), Gurpi (Upper Cretaceous), Kazhdumi (Albian-Cenomanian) and Gadvan (Aptian-Neocomian) formations in the Bangestan anticline. To compare with clay minerals assemblages in these formations, selected samples also taken from available formations in drilled wells in Ahvaz, Marun, Karanj, and ...

Climate is the most important factor of plants distribution in global and regional scale. Understanding the current distribution of vegetation cover and its interaction with climate regularity is important for predicting its future. In order to determine the effective climate factors in plant life-form in Polour rangelands in the Damavand summit (2400 to 4100 m above sea level), Iran, a study w...
