Evaluación de productos IMERG V03 y TMPA V7 en la detección de crecidas caso de estudio cuenca del río Cañar

Abstract: Los productos de precipitación por satélite de la Misión de Medición de Precipitación Tropical (TRMM) y su sucesor la Medición de Precipitación Global (GPM), proveen de datos de precipitación para aplicaciones hidrológicas en cuencas hidrográficas sin datos o información escasa. El propósito de este estudio es evaluar la aplicación de los productos satelitales IMERG V03 y TMPA V7 para modelación hidrológica y la potencial detección de caudales de crecidas en la cuenca del río Cañar. Los productos satelitales I… Show more

“…Recent products that derive rainfall intensity information from meteorological satellite observations complement the in-situ data and are beginning to be used for several purposes, including, for example, the validation and intercomparison of satellite rainfall estimates [18], the analysis of flash floods [19,20], hydrological modeling [21,22,23,24,25], downscaling of rainfall extremes [26], and the estimation of IDF curves [27,28,29,30]. Among these products is the Integrated MultisatellitE Retrievals from GPM-IMERG (or in short IMERG) produced by NASA, a quasi-global dataset (60°N -60°S), calibrated using monthly rain gauge precipitation values, which provides rainfall intensities at 0.5 h intervals, with a spatial resolution of 0.1° (approximately 11 km at the equator).…”

“…In this sense, the optimal prediction of flows is required to allow the necessary measures to be taken not only for the protection, evacuation and warning systems of potential vulnerable areas in the short and medium term, but also for water resources management and territorial planning (Ayala et al, 2018). Another relevant aspect is the evaluation of the hydraulic infrastructure, since when maximum flows occur, these directly affect the useful life of the hydraulic infrastructure, generating uncertainty, especially in emergency situations (Guachamín et al, 2019;Matovelle et al, 2022).…”
