Identification of flood-prone areas in San Cayetano provincial park (Corrientes, Argentina)
The town of San Cayetano and particularly the Provincial Park with the same name, presents recurring cases of flooding in wet periods, mainly after intense rainfall given the almost immediate response of the river flow to inclement weather due to its very small basin.

| description |
The town of San Cayetano and particularly the Provincial Park with the same name, presents recurring cases of flooding in wet periods, mainly after intense rainfall given the almost immediate response of the river flow to inclement weather due to its very small basin. The main objective of the work is to generate a Digital Elevation Model of high spatial resolution and vertical precision of the Park from a drone flight and the use of Geographic Information Technologies. To achieve this objective, measurements of Photogrammetric Support Points (PAF) were first carried out with a South Galaxy G1 geodesic receptor GNSS, which will provide greater reliability to the results generated in the post-processing stage, and San Cayetano Park was flown over with a Mavic 2 pro model drone. from the DJI firm, which has a 1” CMOS sensor and 20 megapixel resolution, which made it possible to obtain aerial photographs with the characteristics necessary for the generation of an DEM. Subsequently, with the use of specific software, these photographs were processed, and a high spatial resolution DEM was generated. From this product, and with the help of Geographic Information Systems, maps were generated that show different possible threat scenarios at certain flood levels based on the advance of water over the study area and in this way contribute to the management and early warning of these events.

La localidad de San Cayetano y particularmente el Parque Provincial San Cayetano, presenta recurrentes casos de inundaciones en períodos húmedos, principalmente luego de intensas precipitaciones, dada la respuesta casi inmediata del caudal del río a las inclemencias del tiempo debido a su cuenca muy reducida. El objetivo principal del trabajo es generar un Modelo Digital de Elevación de alta resolución espacial y precisión vertical del Parque a partir de un vuelo con Drone y la utilización de Tecnologías de la Información Geográfica. Para concretar este objetivo se realizaron en primera instancia mediciones de Puntos de Apoyo Fotogramétricos (PAF) con un receptor GNSS geodésico South Galaxy G1 para otorgar mayor confiabilidad a los resultados generados en la etapa de postproceso y se sobrevoló el Parque San Cayetano con un Drone modelo Mavic 2 pro de la firma DJI, que cuenta con un sensor CMOS de 1” y resolución de 20 megapíxeles, lo que posibilitó la obtención de fotografías aéreas con características necesarias para la generación de un MDE. Posteriormente, con el uso de software específico se procesaron dichas fotografías, y se generó un MDE de alta resolución espacial. A partir de este producto, y con ayuda de Sistemas de Información Geográfica, se generaron cartografías que muestran diferentes posibles escenarios de amenaza en determinadas cotas de inundación a partir del avance del agua sobre el área de estudio y de esta forma contribuir a la gestión y la alerta temprana de estos sucesos.
