| Abstract: | Geomorphological features are essential parts of the environment and they represent an important conditioning factor for the
development and distribution of certain biological assemblages, as well as for a variety of human activities. However, environmental
geomorphology usually receives very limited or no attention at all in the process of environmental impact assessment (EIA).
Nevertheless, the site selection process for hazardous wastes in environmental impact studies for individual projects plays
an essential role. In order to determine the most suitable site in a region for municipal/hazardous wastes, several criteria
are used, including geology, groundwater condition, climate, and land use. The present work describes a methodology taking
advantage of environmental geomorphological features, and reducing these criteria in the site selection procedure in land
disposal of waste; in addition, a case study is presented to demonstrate the applicability of the proposed methodology. The
validity of the adopted site screening method is explained. This methodology comprises the use of a single geomorphological
map to locate suitable landfilling sites for hazardous waste, instead of using separate maps for geological features, climatic
features (temperature, precipitation, and speed and direction of the prevailing wind), slope and erosion. Furthermore, the
present study is compared with a previous study performed in the GAP region, where the use of land resources is crucial for
agricultural and water management purposes. The application of the described selection process and the verified method in
this region shows that the adopted method and detailed criteria are valid. |
