Avaliação do monitoramento hidrometeorológico na bacia hidrográfica do Alto Paranapanema (BH-ALPA) - SP

Abstract

Faced with numerous discussions, both politically and environmentally due to conflicts over the multiple use of water, guidelines for the protection and management of water resources were developed and improved, which culminated in the current Water Law, Law No. 9.433/97. The effective articulation of water governance can occur through adequate integrated management, combined with the application of instruments for managing and monitoring water resources. Hydrometeorological monitoring is an essential strategy to ensure the sustainable management of water resources and prevent natural disasters. Faced with this question, this work aimed to critically analyze quantitative and qualitative aspects, such as the constancy and compliance with current legislation, and the data from the hydrometeorological monitoring networks of the Alto Paranapanema Hydrographic Basin (BH-ALPA). For that, the hydrometeorological database and the legislative references regarding water resources were evaluated in order to raise the quality of this information as well as its effectiveness in the management of the respective basin. The study was carried out through an integrated literature review, whose agenda is characterized by the understanding and analysis of legal issues regarding the monitoring and adaptation to the regulatory instruments of a Hydrographic Basin (BH). To determine the object of the research, the set of data available on HidroWeb was evaluated by checking the pluviometric and fluviometric stations located in BH-ALPA. The duration of the monitoring as well as the quality of the hydrometeorological data deal with critical aspects to guarantee the reliability of the analyzes and studies carried out. It must be ensured that the data is consistent, complete and representative of real conditions and available for long-term analysis to identify trends. The assessment of monitoring conditions at BH-ALPA revealed some inconsistencies and challenges faced. Still, there are gaps in the information that can lead to incomplete and imprecise analyses, making it difficult to make informed decisions. In order to overcome such issues, it is essential to invest in hydrometeorological monitoring infrastructure, including the installation of data collection stations in strategic locations, as stated in the goals of the Basin Plan.
