Question

As a geological engineer, you are assigned to identify a site using remote sensing for the development of a landfill in Nome, Alaska.

1. Clearly describe the steps, the method and the constraints that you would use to identify potential sites for the landfill. Please be specific about the various elements (e.g., sensor, resolution, etc.) that you would utilize in aid of the investigation and justify those clearly. Define clearly the steps in image processing/enhancement that may be utilized in your site identification. Any tools you may use should also be justified.

2. Briefly discuss how your analysis could be extended to a global context and how it would impact or would be impacted in global, economic, environmental, and societal context. You may provide several specific examples to justify your answer

Explanation / Answer

And1. Best site for landfill selecting creteria are:
1. local zoning and land use criteria should met the limitations of weight and transport.
2. Site should be easily accessble in all weather conditions for dumping soildwaste
3. It should bot hamper the quality of ground surface and groundwater.
4. Gas emission from waste is to be controlled.
5. The access for covering of solid waste and for compacting and easily handeling
6. It should not affect the neighbouring areas or environmental sensitive areas.
These siter should have clear idea of regulatory criteria and public opinion.

For the development of new site for landfill , developer should look into these areas.
1. Establish goals for the landfill proper implementation .
3. Design basis and need to be identified.
4. Identify potential sites within the region.
5. Select and evaluate in detail the most desirable sites
6. Select best site for development of landfill
7. regulatory site approval
Potential sites must be in suitable landfill development areas. In the absence of GIS maps, air photographs can be used to assess current land-use patterns.
Soil mapping is also a useful way to findout potential sites but they give information upto depth of 5 feet.

Geographical information system (GIS ) is the high resolution photo on of landuse and provide more clear area.

Soil boring ,hydrological information system are the few methods that provide the mechanism to judge and predict the landfill areas development .

Constrains :
Landfill are used as open space or recreational areas. But areas with endangered plant or animal habitats, virgin timber land, wildlife corridors, unique physical features, and historical and archeological sites should be avoided in locating a landfill.
Developing a landfill in one of these areas can be detrimental to the environment.
These areas are kept away from airports to avoid flying birds in air route.
