Conventional soil survey methods for soils within the watersheds in Iran require a significant budget with many soil surveyors and much time. Additionally, no accurate and reliable information exists on the spatial variability of superface soil parameters in order to predict the soil loss by different models (RUSLE, PISAC, EUPOSEM, MORGAN). Also information on planning and management activities...

results of 1818 hcv rna positive samples, hcv genotypes pcr fragments were detected in 1552 (85.5%) samples. hcv genotype 3a was the predominant genotype (39.4%) followed by genotype 2a (24.93%). hcv genotype 3 was the predominant genotype in punjab and sindh regions, while genotype 2 was the most predominant genotype in khyber pakhtunkhwa region and the second predominant genotype after genoty...

Vegetation due to its root system by creating cohesion of soil particles, significantly affects hill slope mechanical properties related to shallow landslides and slope stability. In this regard, the root engineering characteristics of forest species are important. The aim of this study was to investigate the distribution pattern of persian oak and hawthorn in Zagross forests. For this purpose,...
