The Pantanal is one of the world’s largest freshwater wetlands. The spatial and temporal variability of flooded areas is a key factor for preserving and managing the flora and fauna of this biodiversity hotspot, and thus, its dynamic is crucial to maintain ecosystem services. However, existing inventories of flooded areas with high spatial resolution are scarce or do not represent a continuous time series considering the entire Pantanal wetland. In this study, flooded areas were derived from Landsat and Resourcesat satellite imagery time series for the years 2000 to 2020 through big data analytical tools. Our results show that permanently flooded areas accounted for 3.40% of the total Pantanal wetland and 8.85% of the study area was flooded during only one year, indicating a complex and dynamic fluvial system. In addition, approximately 39% of the basin was composed of non-flooded areas. During the analyzed period (2000–2020), the highest flood event occurred in 2011 covering an area of 57,969 km², followed by 2014, with 52,500 km² (respectively 38.55% and 34.91% of the total area of the Pantanal). The year with the smallest flooded area was 2020 (10,668 km²), 83% lower when compared to the period-based average. The Pantanal is a seasonal wetland, thus, rainfall plays a significant role in the flood pulse, accounting for approximately 60% of the total variability of the flooded areas. The flood dynamics is also affected by the morphology of the modern depositional system of the Pantanal, which is composed by large megafans created by several distributive rivers, and by neotectonics that generates differential movements of blocks creating lower areas that will determine how flood pulse moves spatially and temporally. Therefore, the understanding and analysis of this dynamism becomes an indispensable tool for the public government ordering defining policies for the occupation and the economic zoning of the Pantanal.

潘塔纳尔湿地是世界上最大的淡水湿地之一。洪泛区的时空变化是保护和管理该生物多样性热点区动植物的关键因素，因此，其动态对维持生态系统服务至关重要。但是，考虑到整个潘塔纳尔湿地，现有的具有高空间分辨率的洪泛区清单很少或不能代表连续的时间序列。在这项研究中，通过大数据分析工具从Landsat和Resourcesat的卫星图像时间序列中得出了2000年至2020年的水灾地区。我们的结果表明，永久性洪灾区占潘塔纳尔湿地总面积的3.40％，而研究区的8.85％仅在一年内被洪水淹没，这表明河流系统是复杂而动态的。此外，流域约39％的区域为非淹没区域。在所分析的时期（2000-2020年）中，2011年洪灾发生率最高，占地57,969公里²，其次是2014年，为52,500 km ²（分别占潘塔纳尔湿地总面积的38.55％和34.91％）。洪灾面积最小的年份是2020（10,668 km ²），与基于周期的平均值相比降低了83％。潘塔纳尔湿地是季节性湿地，因此降雨在洪水脉动中起着重要作用，约占洪水泛滥区总变化的60％。潘塔纳尔（Pantalal）现代沉积系统的形态也影响了洪水动力学，潘塔纳尔沉积系统的形态由数条分布河流形成的大型巨型风扇以及新构造运动产生，这些运动产生块体的差分运动，从而形成下部区域，这些下部区域将决定洪水脉冲在空间上的运动方式。和时间上。因此，对这种动力的理解和分析成为公共政府下令制定潘塔纳尔占占和经济分区政策的必不可少的工具。
