The Miringuava Reservoir in southern Brazil is undergoing a digital transformation. Sanepar, the state of Paraná’s water utility, has deployed a fleet of drones and high-precision sensors to map the basin’s topography with a level of granularity previously reserved for high-end urban planning. By capturing thousands of images from an altitude of 120 meters and anchoring them with high-precision GNSS antennas, engineers have produced a digital terrain model with a resolution of 20 centimeters—a massive leap from the five-meter contour lines used in previous decades.
This digital twin allows for a "palm-sized" view of the landscape, according to Sanepar engineer Mauricio Bergamini Scheer. The precision is not merely an exercise in high-fidelity cartography; it is a prerequisite for modern hydrological management. As climate patterns become increasingly volatile, the ability to simulate how the reservoir will fill, how it will behave during extreme droughts, and how it will interact with the surrounding ecosystem is critical for the long-term water security of the Curitiba metropolitan region.
The project serves as a case study in how legacy infrastructure is being retrofitted with predictive technology. Beyond flood simulation, the data helped manage the final stages of vegetation removal, ensuring that the reservoir’s footprint was cleared with surgical accuracy. As cities worldwide grapple with the twin pressures of population growth and water scarcity, the shift toward these hyper-local, high-resolution digital models represents a vital evolution in how we manage our most essential resource.
