“…Lin, Kao (1998) have suggested that the appropriate slope for constructing a landfill is about 8-12%, because too steep slope would make it difficult to construct and maintain and too flat of a slope would affect the drainage. A slope above 12% creates high runoff rates for precipitation.…”

Abstract. Trinitrotoluene (TNT), a commonly used explosive for military and industrial applications, can cause serious environmental pollution. 28-day laboratory pot experiment was carried out applying bioaugmentation using laboratory selected bacterial strains as inoculum, biostimulation with molasses and cabbage leaf extract, and phytoremediation using rye and blue fenugreek to study the effect of these treatments on TNT removal and changes in soil microbial community responsible for contaminant degradation. Chemical analyses revealed significant decreases in TNT concentrations, including reduction of some of the TNT to its amino derivates during the 28-day tests. The combination of bioaugmentation-biostimulation approach coupled with rye cultivation had the most profound effect on TNT degradation. Although plants enhanced the total microbial community abundance, blue fenugreek cultivation did not significantly affect the TNT degradation rate. The results from molecular analyses suggested the survival and elevation of the introduced bacterial strains throughout the experiment. Keywords: TNT, bioaugmentation, biostimulation, phytoremediation, microbial community.

“…[37,38] stated that neither too steep nor too flat land slopes are appropriate for placing a landfill site, and a slope of less than 12% would suitable. In this study a slope of ≤10% was assigned a score value of 0, while a slope of >20% was assigned a score value of 10.…”

Landfill siting was determined within Mafraq City, Jordan, through the integration of geographic information system (GIS), weighted linear combination (WLC) analysis, and remote sensing techniques. Several parameters were collected from various sources in vector and raster GIS formats, and then, used within the GIS-based WLC analysis to select optimum solid waste disposal sites. Namely, urban areas, agricultural lands, access roads, surface aquifers, groundwater table, fault system, water wells, streams, and land slope were considered in this research. Also, the trend of urban expansion within the study area was monitored using the Landsat data of 1989, 1999, and 2009 to support the selection process of disposal sites. It is found that about 84% of the study area was within "most suitable" to "moderately suitable" classes for landfill sites, while the rest of the study area was within "poorly suitable" and "unsuitable" classes. Based on the analysis of Landsat satellite data the urban area was expanded of more than 240% during the last three decades, mainly toward south, and southwest, except the villages near the existing disposal site, where the trend was toward east and northeast. Finally, three sites were suggested as alternatives to the existing disposal site taking into the consideration the environmental, biophysical, and economical variables applied in the GIS-based WLC analysis.

“…Using MCE models, the resulting alternative sites were estimated. (Lin & Kao, 1998) developed a model which was relevant for vector-based data that was incorporated with GIS. The model developed was capable of processing digital spatial data to aid in landfill site study.…”

Landfill is a mode of municipal solid waste disposal. Thus, it is imperative to select relevant site for landfilling in order to curtail environmental damage and harmful impacts on wellbeing of public. Through the decades, rummage around various places for landfill site has been going on concerning its distance from artery road, resident area and water surface in order to prevent serious health and environmental hazards. In case of Nepal, Sisdole landfill site at Okharpauwa VDC in Nuwakot is struggling to manage garbage produced by the Kathmandu valley. The valley alone mounds to 700 metric tons of garbage on a daily basis that would loosened carrying capacity of the place really soon. With the intention of uncovering suitable site for alternative to present disposal site, the Multi criteria method has been applied in GIS domain. Here, data layers of land use pattern, residential areas, urban areas, roads and water bodies of the Kathmandu, Lalitpur and Bhaktapur district were mainly considered. The buffer zones were created to those 5 layers assigning various decisive factors to determine area around them within a certain distance. Then, weightings were assigned to each criterion as per their relative importance and ratings. Furthermore, weights were integrated in GIS environment to generate suitable site. Lastly, comparative study of data layers suggested that next site for dumping refuse could be the Bhaktapur district.
