Flood hazard assessment is a fundamental step in flood risk mapping. Quantitative requires hydrodynamic modelling of the flooding process order to calculate spatial distribution suitable indicators representative intensity and frequency, hence its potential result harm. are usually defined by combining relevant parameters, mainly depth flow velocity, but also arrival time, duration, sediment or...
The risk of plastic debris, and specifically micro(nano)plastic particles, to ecosystems remains be fully characterized. One particular issue that warrants further characterization is the hazards associated with chemical additives within as they are not chemically bound polymers can persistent biologically active. Most plastics contain therefore potential vectors for introduction these chemical...
Background and Objectives: Chemical hair color are one of the most widely used cosmetics. The presence of heavy metals in these products can affect the health of consumers. Unlike other cosmetics, no study has been conducted on the heavy metal levels in the synthetic chemical hair colors. This study determined the concentration of heavy metals in these products and the risk assessment of non-ca...
Seismic hazard assessment like many other issues in seismology is a complicated problem, which is due to a variety of parameters affecting the occurrence of an earthquake. Uncertainty, which is a result of vagueness and incompleteness of the data, should be considered in a rational way. Using fuzzy method makes it possible to allow for uncertainties to be considered. Fuzzy inference system,...
Desertification is the result of a series of important processes. Among them, climate change and human activity are the most important. Arid and semi-arid regions cover a vast area of Iran (85%). The hazard assessment of desertification and preparation of desertification intensity maps are key tools for management of desert regions. This research assessed the efficiency of the MICD model for ha...
