Título:
Methodologies for pollution risk assessment of water resources systems
Resumo:
Water resources systems (both surface water and groundwater resources) are subject to different anthropogenic pollution impacts. Their intrinsic characteristics to better support pollution impacts or on the other hand their intrinsic vulnerability to pollution may or may not allow them to resist pollution accidents of different types. The assessment of water resources systems vulnerability to pollution is therefore not only important per se but also relevant for drawing of pollution risk maps. In this paper a brief approach for the assessment of recently developed methodologies for risk assessment of water resources systems to pollution is presented. Some of the methodologies were applied in the Jiang su Province case-study area (PR China). That application required the GIS mapping of several parameters that were considered to influence vulnerability and risk. The expected influence of those factors is integrated using indexes. The final results enable the mapping of risk of surface and groundwater resources.
