Development of a ground platform to measure runoff data in rivers in the brazilian semiarid region

The occurrence of floods dates back to the history of human civilization, and in recent years it has been increasing significantly. To minimize the risks and mitigate the damage caused by extreme events, an efficient warning system must exist. In Brazil, river discharge data are produced by means of fluviometric stations maintained by government agencies. A promising solution is the application of tools that employ image-based approaches, where it is possible to determine the surface velocity of the riverbed from a particle image velocimetry (VIP) analysis. To correct the topography of the riverbed, LIDAR sensors and structure-of-motion photogrammetry (EDM) techniques can be employed in association with the tool applied to determine surface velocity fluxes. After the generation of raw runoff data there will be a calibration and treatment of the obtained data. In this context, the objective of the project is to develop ground platforms capable of performing real-time estimates of river discharge. It is expected that after the development of the data collection platform it will be possible to apply the tool in the areas of sedimentology, hydrology, water quality simulation, urban macrodrainage, power generation, among others.
