Application of bathymetry in water bodies in urban areas of the five Brazilian regions

Abstract

The problems occurring in water bodies can be studied and researched using bathymetric data, associated or not, with geospatial technologies. The objective was to identify the application or not of this association, and the types of water bodies, in the five regions of Brazil from 2014 to 2023. The methodology employed was the combination of comparative and historical processes, using past data. The data obtained and analyzed indicated that the dichotomy between bathymetry associated with other aspects of water resources, such as turbidity, is expanding in the five Brazilian regions, especially in the northern region of the country, due to the occurrence of the largest hydrographic basin, both in extension and in water volume, which could contribute to environmental, water, and fluvial geomorphology management. However, in regions where water use is scarce due to the absence of a more expansive water network, such as the northeast region, the application of this association is still scarce. Therefore, greater employability of bathymetric data is necessary for studies and research in water bodies in both the northeast and southeast and south regions of Brazil.
