<p>The application of remote sensing for monitoring, detecting and analysing the spatial and extents and temporal changes of waste dumping sites and landfills could become a cost-effective and powerful solution. Multi-spectral satellite images, especially in the thermal infrared, can be exploited to characterize the state of activity of a landfill.  Indeed, waste disposal sites, during the period of activity, can show differences in surface temperature (LST, Land Surface Temperature), state of vegetation (estimated through NDVI, Normalized Difference Vegetation Index) or soil moisture (estimated through NDWI, Normalized Difference Water Index) compared to neighboring areas. Landfills with organic waste typically show higher temperatures than surrounding areas due to exothermic decomposition activities. In fact, the biogas, in the absence or in case of inefficiency of the conveying plants, rises through the layers of organic matter and earth (landfill body) until it reaches the surface at a temperature of over 40 ° C. Moreover, in some cases, leachate contamination of the aquifers can be identified by analyzing the soil moisture, through the estimate of the NDWI, and the state of suffering of the vegetation surrounding the site, through the estimate of the NDVI. This latter can also be an indicator of soil contamination due to the presence of toxic and potentially dangerous waste when buried or present nearby. To take into account these facts, we combine the LST, NDVI and NDWI indices of the dump site and surrounding areas in order to characterize waste disposal sites. Preliminary results show how this approach can bring out the area and level of activity of known landfill sites. This could prove particularly useful for the definition of intervention priorities in landfill remediation works.</p>

Difficult Issue

Groundwater asset the executives is a difficult issue looked by practically all the nations. Numerical models of these issues frequently end up being not well characterized subject to a few factors and requirements. This examination is centred on the variety of physico-substance boundaries in water tests undergone with 2 unique destinations. The Dissolved Oxygen substance and Total Dissolved Solids substance of a large portion of the examples are past as far as possible. The chloride satisfied close to the dump-site is seen as extremely high contrasted with the non-dirtied site. Refined calculations are required so as to manage such issues. In the consideration has been paid to heuristic strategies like hereditary calculations and so on which can undoubtedly take care of such issues. Further, so as to handle the enormous number of included boundaries in these issues equal form of GAs is more successful than the fundamental gallium. In this magazine, an endeavour is finished to audit the use of equal variant of GA on groundwater contamination issues.

Value Of Education

When I was growing up in the 1950s in one of the poorest neighborhoods in the urban Delta, the closest I came to an anthropologist was the man who dug the dump site near our home looking for old scrap iron to sell. Certainly there was no expectation for me to become an anthropologist from my grandmother, the matriarch of our family. However, she had moved to the city after the death of her husband with expectations of a better life for her four girls. Stressing education as "the way out," she told stories about her slave uncle who recognized the value of education and learned to read from two young girls he drove to school. In turn, he taught this daily lesson to his family around the fire each night. The many evenings sitting on our front porch, and on the front porch of neighbors, watching and listening to grandma's stories and the stories of others, set a foundation for anthropology in my life and led to my becoming a medical anthropologist.

Local Safety

The mining waste of open pit mines is usually piled-up in dump sites, making a man-made hill more than tens of meters high. Because of the loose structure of the dump sites, landslides or debris flow may occur after heavy rainfall, threatening local lives and properties. Therefore, dump stability analysis is crucial for ensuring local safety. In this paper, a collaborative stability analysis based on multiple remote sensing technologies was innovatively conducted at the Xudonggou dump of the Anqian iron mine. A small baseline subset (SBAS) analysis was used to derive the spatial and temporal distributions of displacements in the line-of sight (LOS) over the whole study area. The deformation in LOS is translated to the slope direction based on an assumption that displacements only occur parallel to the slope surface. Infrared Thermography (IRT) technology was used to detect weak aquifer layers located at the toe of possible landslide bodies. Then, numerical simulations based on the limit equilibrium method were conducted to calculate the factor of safety for three profiles located on the dump site. The results, emerging from multiple remote sensing technologies, were very consistent and, eventually, the landslide hazard zone of the Xudonggou dump site was outlined.
