MORPHOMETRY TO THE SOLID WASTE DISPOSAL AREA OF THE MUNICIPALITY OF NORMANDIA, RORAIMA, BRAZIL
The development of new urban centers necessarily requires planning and disposal of solid waste. The absence of morphometric analysis in areas with the potential to negatively impact the environment and its natural resources can make it difficult to properly understand the contaminant flow in the local hydrological dynamics. The area under consideration in this research comprises the open-air dump in the municipality of Normandia, State of Roraima. Morphometric analysis based on physical characterization were used in the present work with the aid of remote sensing images and radar images to obtain thematic maps and infer how the contaminant flow can interact with the environment and possible directions flow. The drainage basin of the Passarinho stream (water body present in the area) is characterized by a preferential flow in the NE-SW direction, with a predominance of moisture conservation slopes in the perimeter of the disposal area, which favors infiltration. Although the area is strategically positioned away from water bodies, it is in a sedimentary cover, which has a high vulnerability to groundwater contamination, in addition to being an area with a high propensity to flooding, which allows for the dilution of surface contaminants, being able to reach the adjacent streams and lakes.
