The pressure that humanity applies to the environment is reaching alarming levels. Prevention, mitigation and recovery measures need to be put into practice to conserve the environment for future generations. In cases such as large-scale gully erosion, the problem of soil removal is irreversible, but adequate management could stabilize this impact. In this sense, we studied the Palmital stream watershed in Minas Gerais state, Brazil, and applied a new approach to the study of gully erosion based on two main aspects: the temporal evaluation of gullies using multifractal and lacunarity analysis and a proposition for a new gully design (a complex of gullies). Using remote sensing and geoprocessing, we obtained images of the gullies in the Palmital stream watershed for the years 2002, 2007, 2014 and 2016; the gully designs were binarized and used in two free software programs Multifractal Analysis and Scaling System (MASS), from the International Potato Center (CIP), Peru, and FracLac, a plugin for ImageJ from the National Institutes of Health (NIH), United States of America, to perform multifractal and lacunarity analyses. After that, we segmented the entire watershed image and re-evaluated it using the same software. We found that the gullies were multifractal, translationally invariant, not random, relatively homogeneous and grouped, which means that these gullies behave more as groups linked to an environmental characteristic (fault and shear zones with northwest-southeast direction, for instance) than individual gullies. Therefore, we proposed a new classification called the complex of gullies to rearrange their designs as connected features. Then, we performed multifractal and lacunarity analysis of these new complex images, following the same steps as those performed on the initial images, and found better results compared to the former designs. This new approach could help land managers prevent gully advancement and develop more efficient recovery projects, and we recommend further studies to improve the validation of the proposition.
