Abstract

With the recurrence of meteorological events of extreme precipitation in the Paraíba do Sul river basin in its São Paulo fraction, in the opposite direction due to anthropic effects, the vegetation cover with high mitigating potential for impacts on the river and its tributaries has declined. To analyze the current status of this resource we will use data from ANA, CRPM and INPE to make comparisons, graphs and find trends that relate land use, precipitation and river discharges in the meso-basins that supply the Paraíba do Sul River Basin, using data from the last 40 to 80 years. We will also install low-cost precipitation and discharge stations, developed at UNIVAP in select points of the Paraíba do Sul micro-basins, sending data instantly via the internet, testing the versatility of this equipment for monitoring precipitation, quantity and quality of the water in the micro basin in real time (internet of things). The tools have the potential to monitor an area of the Basin much more complete in real time with low costs.
