Gestão de recursos hídricos em ambientes urbanos costeiros: modelagem e representação do conhecimento em sistemas de informação geográfica.

Abstract

The modeling and representation of knowledge in geographic information systems (GIS) are addressed in this work from the perspective of decision support in the management of water resources in coastal environments. In this sense, a systematic observation of a management team is carried out regarding the conduction of decision-making processes in a coastal urban area chosen as a case study. The modeled decision-making processes consider the interrelationships between water and urban planning in order to minimize the social, economic and environmental impacts that may occur when urban problems directly related to water resources are not considered in a planning context. The decision-making process is consolidated and converted into information plans through spatial analysis and inferences of a geographic information system. The GIS, considered in this research as a support system for spatial decision, is the information management tool, is a support tool in the estimation of incomplete and / or absent data based on the accumulated knowledge of the consulted specialists, in addition, the interactions possible between the management team and the available tools are observed based on the principle that the decisions to be made can be better supported with such a system. The analysis and spatial inference resources of the geographic information system are exploited in order to expand the decision support capacity of these systems and, at the end of the implementation, technical guidelines are obtained for the integrated management of surface and underground waters, in addition to guidelines techniques for the integrated management of surpeficial and groundwater, as well as urban guidelines for the occupation of the chosen area.
