Reducing the amount and intensity of surface runoff, thus reducing erosion is one of the important aspects of natural resource management, watershed management and soil conservation. Land surface conditions and particularly vegetation is Mitigating or aggravating factor in erosion. Studies on the effect of ground cover to reduce erosion rates indicate that is not necessary to ground cover to re...

Soil erosion is an important economical, social and environmental problem requiring intensive watershed management for its control. In recent years, modeling has become a useful approach for assessing the impact of various erosion-reduction approaches. ِDue to limited hydrologic data in mountainous watersheds, watershed modeling is, however, subject to large uncertainties. In this study, SWAT200...

   Analyzing variability of measured runoff and soil loss data under different condition of measurement system, are critical for advancing erosion science, evaluating hydrologic models, and designing erosion experiments. For this purpose, the current study aimed to evaluate how runoff and soil loss are influenced by hillslope direction and length in Sangane arid rangeland, Razavi Khorasan Provi...

Despite of soil disturbance, transfer to the laboratory and preparation inside the plots which themselves lead to lower validity of the results, the experimental study on runoff and erosion at plot scale with many research advantages are inevitable. However, there has been less attention to evaluate the effects of soil preparation on runoff and sediment variables. The present study was therefor...

    Soil surface rock fragment is considered as an important factor on runoff and soil erosion. However, few studies have been focused on quantitative evaluation of the effect of soil surface rock fragments on runoff components as an integral part of soil erosion process especially in natural conditions. The present study has been conducted to evaluate the effect of soil surface rock fragments ...

over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
