                         Santa Fe - Argentina (31º 10´ Sur y 61º 50´ Oeste). Para tal fin 
                         se compararon siete algoritmos de clasificaci{\'o}n, dos no 
                         supervisados: clasificaci{\'o}n polarim{\'e}trica H - alpha y 
                         coherencia interferom{\'e}trica; y cinco supervisados: umbral

                         inundaci{\'o}n, {\'{\i}}ndice de vegetaci{\'o}n inundada y 
                         cociente) y par{\'a}metros polarim{\'e}tricos. Estos algoritmos 
                         se validaron a trav{\'e}s de la matriz de error obteni{\'e}ndose 
                         una fiabilidad global del 83,4% para el seleccionado, resultante 
                         de la aplicaci{\'o}n conjunta de los m{\'e}todos supervisados de 
                         Umbral Manual y Detecci{\'o}n de Cambios. El mismo presenta como 
                         ventajas: simplicidad y rapidez, la explotaci{\'o}n de los 
                         conjuntos de datos de observaci{\'o}n de la tierra (Big Data EO), 
                         la f{\'a}cil selecci{\'o}n de umbrales y la capacidad para 
                         delimitar tanto las superficies abiertas inundadas como las 
                         cubiertas por ciertos cultivos. ABSTRACT: The main objective of 
                         this research is to contribute to the determination of flooded 
                         surfaces in plain areas, through the use of SAR, Sentinel 1B 
                         satellite, C band and VV-VH polarizations. The case study is a 
                         sector of the upper basin of the Arroyo Culul{\'u}, located in 
                         the Province of Santa Fe - Argentina (31º 10´ South and 61º 50´ 
                         West). To this end, seven classification algorithms were compared, 
                         two unsupervised: H-alpha polarimetric classification and 
                         interferometric coherence; and five supervised: manual threshold, 
                         change detection (flood index, flooded vegetation index and 
                         quotient) and polarimetric parameters. These algorithms were 
                         validated through the error matrix, obtaining an overall 
                         reliability of 83.4% for the selected algorithm, resulting from 
                         the joint application of the supervised methods of Manual 
                         Threshold and Change Detection. It presents as main advantages: 
                         simplicity and speed, the exploitation of Earth observation data 
                         sets (Big Data EO); the easy selection of thresholds and the 
                         ability to delimit both rural areas flooded with open water and 
                         those covered by certain crops.",
