Decision support system applied to water resources management: PCJ Basins case study

Abstract

Objective: Presenting the particularities of the PCJ Basin Decision Support System (SSD PCJ), highlighting its contributions to the management and planning of water resources. Methodology: Case study based on the application of the SSD PCJ to the management actions of the PCJ Basins. Relevance: Technological advancement implied an increase in data on water resources, requiring more time and effort to be manipulated and analyzed. Thus, investments in databases and systems that transform data into useful information are necessary, so that they can be easily accessed by users in their water resources management and planning processes. Thus, the experiences of the application of the SSD PCJ to the management of the PCJ Basins were discussed and can be replicated in other hydrographic regions. Results: The discussions indicate that the SSD PCJ has characteristics that enhance its application to the management and planning of water resources, with public disclosure of both historical and real time data, allowing users to compare different periods and monitoring points, as well as integrated quality and quantity analyses. Contributions: The application of the SSD PCJ has been shown to be effective in monitoring the occurrence of rain and the water bodies situation, enabling in real time the identification of risk situations and the issuance of alerts to minimize adverse impacts, besides assessing compliance with regulatory standards, feeding simulation models, and supporting analyses of water availability and quality.
