Sumario:The pulsating dynamics condition the characteristics, permanence and distribution of the river landscape and urban occupation. In this work, the landscape units in the flood plain of a section of the Santa Lucia River, belonging to the Paraná River basin, were mapped with the attributes of the hydrosedimentological pulse for different landscape units. Planimetric surveys were carried out and the landscape units were classified using the Ecological Land Classification system and mapped using supervised classification. Using Pulso software, FITRAS attributes were calculated for each landscape unit. which were then summarized, explained and grouped according to similarities and differences, using multivariate analysis methods. Maps of pulse attributes were made establishing 4 categories according to the correlation and similarity between them. Through the mapping it was determined that the vegetation maintains a certain pattern of organization in each section of the river, the trees, shrubs and herbs occupy different positions in the topographic gradient, remaining most of the year in high water (lakes), sand bars, marshes with short and tall grasses, and in low water, marshes with shrubs, marshes with tall grasses and palms and forests dominated by one species and mixed riparian forests. The similarities and differences in the distribution of these landscape units allowed the development of the flood zoning map.  Matching the landscape of the flood plain with the pulse rate and processing of satellite images provides a useful tool for flood management.
