Pollution and Potential Ecological Risk Assessment of Pb, Cd, Cr and Ni in Surface Soils Along some Roads of City of Hamedan
Background & Objective: The road traffic has become one of the main sources of metal pollution and could affect roadside soils. Therefore, this study was conducted to assess the pollution and toxicity potential of Pb, Cd, Cr and Ni in surface soils along some roads of city of Hamedan in 2019. Materials & Methods: In this descriptive cross-sectional study, a total of 63 surface soil samples were...
متن کاملGIS-Based Rockfall Hazard Assessment in Support of Decision Making
When designing infrastructure, settlements or facilities in mountainous areas, rockfall hazard assessment is considered essential, as it is a major hazard worldwide. Rockfall hazard estimation can help greatly in the design of countermeasures, such as barriers and net fences, in order to protect the built environment, as well as for landuse planning. Rockfall modelling is considered an effectiv...
متن کاملA methodology for physically based rockfall hazard assessment
Rockfall hazard assessment is not simple to achieve in practice and sound, physically based assessment methodologies are still missing. The mobility of rockfalls implies a more difficult hazard definition with respect to other slope instabilities with minimal runout. Rockfall hazard assessment involves complex definitions for “occurrence probability” and “intensity”. This paper is an attempt to...
متن کاملWork in Motion: Interpretation of Defects along the Roads
This paper reports findings based on an ethnographic study of an occupational group, the road inspectors, at the Swedish National Road AdministrationProduction. We examine current work practice where the inspectors conduct a truly mobile work, since they are constantly on the move. It is not a fact of movement between different work places, seeing that the continuous movement could be understoo...
متن کاملRisk Assessment of Extreme Events along a River Flow
The present work considers the Struma River water flow on Bulgarian territory as a starting point for evaluation of maximum and minimum water flow using an original integral method. The risk assessment is determined by specific indices like the index Mmax,i for the deviation of the maximum water flow from the calculated norm of the maximum flow Qmax,0 and the index Mmin,i for the deviation of t...
