Identification and Characterization of Dust Source in Khorasan Razavi Province

Background and Amis: One of the phenomena in arid and semi-arid regions is dust storm. Dust is one of the environmental issues that affect the quality and pollution of the air, human health, soil fertility, visibility, economy, and many social and environmental aspects of the community. The present research has been carried out to identify and characterize the areas of dust source in Khorasan...

Dust source mapping using satellite imagery and machine learning models

Predicting dust sources area and determining the affecting factors is necessary in order to prioritize management and practice deal with desertification due to wind erosion in arid areas. Therefore, this study aimed to evaluate the application of three machine learning models (including generalized linear model, artificial neural network, random forest) to predict the vulnerability of dust cent...

Identification of Dust Source Areas and its Characteristics in Eastern Iran

Introduction: Dust storms are natural hazards that effects on weather conditions, human health and ecosystem. Atmospheric processes are directly affected by the absorption and diffusion of radiation by dust, and dust in the cloud acts as a nucleus of congestion. The main dust regions in the world are arid topographies that have soil that is vulnerable to erosion and poor vegetation, easily erod...

Source Camera Identification Based on Sensor Dust Characteristics

A problem associated with digital single lens (DSLR) cameras is sensor dust. This problem arises due to dust particles attracted to the sensor, when the interchangeable lens is removed, creating a dust pattern in front of the imaging sensor. Sensor dust patterns reveals themselves as artifacts on the captured images and they become more visible at smaller aperture values. Since this pattern is ...

Identification of critical sediment source areas across the Gharesou watershed, Northeastern Iran, using hydrological modeling

In this study, the process-based watershed model, Soil and Water Assessment Tool (SWAT), was used for simulating hydrology and sediment transport in the Gharesou watershed and for identifying critical areas of soil erosion and water pollution. After model calibration and uncertainty analysis using SUFI-2 (Sequential Uncertainty Fitting, ver. 2) method, the outputs of the calibrated model were u...
