Abstract

The Brazilian Constitution lists some biomes and ecosystems considered as national patrimony, among which the Pantanal Matogrossense is inserted, legally establishing conditions that ensure the preservation of the environment, including the use of its natural resources (Article 225, § 4). In this context, the research proposes to analyze the dynamics of the floodflow in the Pantanal of Cáceres/MT and aims to contribute a methodology to obtain results that can support the planning, management, and monitoring of natural resources, as well as providing important information for agriculture, geology, hydrology, and ecological models. In this research, images from the MODIS sensor from the year 2015, with a resolution of 250 m, were used for the application of the methodology. The software ArcGis and Matlab were used for the image processing. The normalized difference water index obtained through 500 m resolution MODIS images was used as a priori analysis of the regions with water and without water, after a threshold was defined for all of the images and the processing was done to obtain the matrix with days with water and without water in the studied area. The results obtained provide a classification for the floodflow, the quality parameters derived using study area show that the proposed method performed better with classes < 30 (96%) and 180 - 270 (90%) of 4% and 10% of false positives, respectively.
