Introduction: Landfill siting is a difficult, complex, and protracted process, which requires evaluating different criteria. A suitable site should be located to dispose the municipal solid wastes hygienically (sanitary landfill), which is one of the fundamental subjects related to the environmental stability of the human settlements. The aim was to select a suitable waste disposal area using f...

With the ever-increasing human population, there is a need to develop new urban settlements for habitation. For these settlements, it imperative optimally site different land-use zones, including solid waste disposal sites. The aim of this article determine suitable sites locating landfill in developed city Zimbabwe around Mt. Hampden, named New City. City will have various residential, commerc...

We describe two current projects with our toolkit for siting multiple observers on terrain. (Both observers and targets are at some specified height above ground level. Observers can see targets, when not hidden by the terrain, out to a specified radius of interest.) Siting the observers so that they are intervisible, i.e., so that the visibility graph is a connected set, is the first project. ...

The siting of an increasing range of facilities has become a major policy problem for all nations alike. Developers often face significant resistance from community interests in seeking to site socially desirable facilities. Siting is inherently political. While in some cases, developers are unable to get community agreement for projects, in others, they have had more success. This overview pap...

In this study the concept of biofilm accumulation in the sand column was promoted to assess the changes in hydraulic conductivity and concentration of organic contaminants of the synthetic leachate. Four different combinations of column study were carried out using synthetic leachate as a substrate solution. Mixed and stratified mode of experiments with two different sizes (0.3 mm and 0.6 mm) o...
