El {\'a}rea de estudio es la cuenca superior del Arroyo
Culul{\'u}, localizada en el centro oeste de la Provincia de
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
manual, detecci{\'o}n de cambios ({\'{\i}}ndice de
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.",
