Unlocking the Potential of Smart Watersheds: Leveraging Iot and Big Data for Sustainable Water Resource Management and Indicator Calculation

The present work aims to show how the Water Quality Indicators (IQA), defined in the Brazilian legislation, can be obtained using Information and Communication Technologies, such as the Internet of Things (IoT) and Big Data, and organizing them in decision support systems. This allows a decision based on up-to-date data and evidence, turning the water management smarter. Methodologically, based on bibliographic and documentary data, it describes and evaluates the use of IoT and Big Data in calculating indicators applied to water resource management. The study also shows, in a practical way, how anetwork of sensors obtains the necessary data for the calculation of the Water Quality Indicator and how they were calculated using Big Data applications. With this, the results demonstrate how Information and Communication Technologies (ICTs) can be used to calculate different indicators in the management of water resources and, with the conceptual elements exposed here, provide greater familiarity with the theme of intelligent watersheds to fill a literature gap.
