Abstract: The minimum shear stress is a relevant design parameter in sewage collection networks, as it directly influences the geometric characteristics of the system and the costs associated with its implementation. In this context, this study evaluated the influence of variations in minimum shear stress on the implementation costs of a sanitary sewage system, based on the design of a sewer network in an urban area. Four design scenarios were analyzed for the same network layout, defined by different minimum shear stress values, while maintaining all other hydraulic and constructive assumptions constant. The network design was carried out using the CEsg software, and the resulting physical quantities supported the preparation of cost estimates based on SINAPI unit prices. The results indicated that increases in minimum shear stress are associated with deeper trenches and higher excavation and shoring quantities, leading to an overall increase in implementation costs. The comparative analysis enabled the systematization of results through dimensionless cost factors, as well as the derivation of unit costs and cost equations as functions of minimum shear stress, which can be applied as a decision-support tool in preliminary technical and economic analyses of sewage collection network projects.

To this end, rainfall data obtained from INMET and CEMTEC, flow data from the UHE Jupiá hydrometric station provided by ANA, hydrogeological information from the RIMAS network, Sanesul, and wells authorized by IMASUL, as well as spatial data from MapBiomas relating to forestry areas were used. The analyses involved the temporal evaluation of static well levels, correlating them with precipitation, flow, and spatial distribution indices of eucalyptus cultivation areas. The results indicated that the observed oscillations in groundwater levels may be related to climatic variability. In the Sanesul water supply wells, evidence of influence associated with pumping and exploitation of groundwater was observed. However, the absence of continuous historical monitoring series made it impossible to conclusively confirm this influence. Similarly, it was not possible to prove a direct relationship between forestry areas and aquifer drawdown, due to the lack of monitoring wells located near the planted areas. The limitation and discontinuity of the available data restricted the scope of the analyses, highlighting the need to expand the hydrogeological monitoring network in the region.

According to Federal Law No. 9,985/2000 (SNUC), Art. 9, Ecological Stations are Conservation Units aimed at nature preservation and scientific research, where public visitation is prohibited except for educational purposes (BRASIL, 2000). Under this prerogative, the Serra das Araras Ecological Station contributes to the maintenance of the ecological integrity of the Cerrado (ICMBio, 2016). The present study analyzed the temporal dynamics of vegetation cover in the Serra das Araras Ecological Station, Mato Grosso, between 1986 and 2025, including a comparative evaluation between the Buffer Zone and the interior of the Conservation Unit. The methodology was based on the digital processing of images from the Landsat 5 satellite, referring to the year 1986 (USGS, 1986), and Landsat 8, referring to the year 2025 (USGS, 2025), with the application of the Normalized Difference Vegetation Index (ROUSE et al., 1973). From this procedure, vegetation cover maps of the conservation unit area and its surroundings were generated in a Geographic Information System (GIS) environment using the QGIS software (QGIS DEVELOPMENT TEAM, 2024). The results reveal significant changes in the landscape, mainly in the Buffer Zone, where Dense Vegetation underwent retraction, declining from 36.28% to 14.57% of the total area. Concurrently, an expressive expansion of the Grassland class was observed, which came to represent 54.81% of the landscape in 2025, in addition to a 16.87% increase in Exposed Soil areas. The individualized analysis of the interior of the Conservation Unit demonstrated a distinct behavior, with a less intense retraction of Dense Vegetation and a reduction in areas classified as Exposed Soil, indicating greater ecological stability when compared to the surroundings. The significant decrease in dense forest in the Buffer Zone, combined with the fragmentation of vegetation cover, highlights the intensification of anthropogenic pressures around the unit. However, the results indicate that, despite the recorded losses, the core of the Ecological Station still maintains significant portions of tree cover, suggesting that the unit has relatively fulfilled its environmental protection function in the face of the transformations occurring in its surroundings. The study reinforces the relevance of the integrated use of remote sensing and geoprocessing techniques as accessible and efficient tools for environmental monitoring in time series, supporting conservation actions and decision-making.

In view of Law No. 11,445, dated January 5, 2007, which seeks to universalize access and effective service provision, this research intends to analyze the spatialization and socioeconomic characteristics of the locations served by sanitation infrastructure in the country. The research is based on data from the 2022 Demographic Census and uses indicators related to population composition, average income, and access to the general water supply network, sewage system, and lack of bathrooms and toilets. The methodology employs Exploratory Spatial Data Analysis (ESDA) techniques, using GeoDa and QGIS, with calculations of the Global and Local Moran Index (LISA), allowing the identification of autocorrelation patterns and territorial clusters. The results show strong regional inequalities. The North and Northeast regions have higher proportions of non-white populations, lower income levels, and worse sanitation indicators, including low percentages of coverage by the general water and sewage network and a higher occurrence of households without bathrooms. In contrast, the Southeast and South regions have higher average incomes and greater coverage of water and sewage services. Conditional maps reveal that income is the main determinant of access to sanitation, but its relationship with racial composition indicates overlapping vulnerabilities. The integrated analysis suggests the persistence of a sociospatial pattern of exclusion, revealing evidence of environmental racism and structural inequalities that affect access to water and sanitation.
