This process impacts various areas, and its measurement is a critical tool for adopting management strategies and conservation practices. Mathematical models can estimate soil losses under different environmental conditions. When integrated with GIS environments, these models significantly reduce execution and study costs, while generating valuable information, creating maps, and characterizing the environment. This study aimed to perform a systematic literature review on mathematical models for soil and water loss and to highlight some of their applications through the analysis of articles published in journals and indexed in electronic databases. Over the years, various models have been developed, and their use has proven essential for implementing conservation practices and restoring degraded areas. Due to the complexity of the process, it is crucial to consider the parameters available in each situation to select the most appropriate model.</p> Nayme Soares Guedes Camila de Sousa Queiroz Almeida Caio Herman Teixeira de Oliveira Marlon Fernandes Ramos Huézer Viganô Sperandio Daniel Brasil Ferreira Pinto Rafael Alvarenga Almeida Copyright (c) 2025 International Journal of Geoscience, Engineering and Technology https://creativecommons.org/licenses/by-nc-sa/4.0 2024-12-02 2024-12-02 11 1 1 10 Study on Mass Movement Risk Area in The Manoel Pimenta Neighborhood in the City of Teófilo Otoni/MG http://geovales.com/index.php/Journal/article/view/171 <p>Brazil is a country with great climatic, geological and socioeconomic diversity. One of the main problems faced in urban centers is the occupation of land, mostly by an economically vulnerable population, in areas at risk of movement of massive soil or in areas of flooding, putting them at risk of material, health and life. This work aims to identify, classify and recommend technical solutions in an area at risk of slope sliding in the Manoel Pimenta neighborhood, in the city of Teófilo Otoni. A history of mass movement and the imminence of new mass movement were noted in the study area, where there are 3 residences, all classified as R4 (High Risk), requiring intervention from public bodies and owners to mitigate risks.</p> Helio Soares de Aguilar Junior Antônio Jorge de Lima Gomes Hiago Félix Santos Thais Mayara Rodrigues Gomes Thiago Ferreira de Araújo Copyright (c) 2025 International Journal of Geoscience, Engineering and Technology https://creativecommons.org/licenses/by-nc-sa/4.0 2024-12-02 2024-12-02 11 1 11 18 A study on dynamic non-destructive testing of ground anchorages - dynamic stiffness method http://geovales.com/index.php/Journal/article/view/191 <p style="text-align: justify;">This present paper analyzes an anchored retaining wall using a non-destructive dynamic test, which is based on the variation of the dynamic stiffness of the ground anchors, applied to a real case study. The main objective is to evaluate the applicability and particularities of the method to identify the structural integrity of the anchorages, including their free, total and anchored lengths, as well as their current working loads. The results indicated that the dynamic stiffness of the anchorages varied around 5.0E8 N/m, while the working loads found were values between 74.6 kN and 107.9 kN. The analyses performed indicated that the dynamic stiffness of the anchorages did not present large variations along the anchored wall, proving that the determined lengths accurately reflect the real situation of the anchorages. In addition, a very isonomic distribution of forces was obtained, evidenced by the stiffness values obtained. The method stood out for its practicality in execution and analysis of results, consolidating itself as an effective and non-destructive tool for structural evaluation. Despite the general ease of the method, the study reinforces the need for technical experience in the interpretation of specific steps of the procedure, especially in cases with more complex structural behavior. The test proved to be a reliable solution for the continuous monitoring and diagnosis of containment systems, meeting the requirements of normative inspections and contributing to preventive maintenance. Thus, the work reinforces the potential of the method to ensure the safety, structural performance and longevity of anchored walls.</p> Emanuel Gomes Cândido Coelho Lucas Deleon Ferreira Jean-Jacques Rincent Antônio Jorge de Lima Gomes Armando Belato Pereira Marcos Túlio Fernandes Ticiane Schivittez Elacoste Thiago Bomjardim Porto Copyright (c) 2025 International Journal of Geoscience, Engineering and Technology https://creativecommons.org/licenses/by-nc-sa/4.0 2025-01-29 2025-01-29 11 1 19 30 Creeping Trends and Risk Assessment in Teófilo Otoni: A Case Study on Presidente Prudente Street http://geovales.com/index.php/Journal/article/view/188 <p>This study investigated the creeping phenomena on Presidente Prudente Street, Jardim São Paulo neighborhood, in Teófilo Otoni – MG, using an approach that combined literature review, field analysis, and the application of guidelines from the Ministry of Cities for risk mapping. During the field survey, various indicators of creeping were observed, such as trees with abnormal inclinations, soil cracks, and abandoned buildings with signs of structural deformation. Based on these observations, the area was preliminarily classified as Medium Risk (R2), although this assessment is an initial interpretation. The instability of the terrain and the presence of mass movements indicate potential risks to the safety of constructions in the studied area. This research identified physical signs of these geological phenomena, demonstrating the vulnerability of this location and warning against unplanned urbanization. The study contributes to understanding the geological processes affecting Teófilo Otoni, providing a basis for future studies and interventions aimed at safety and sustainable urban planning in the region.</p> Luiz Felipe Amaral Silva Antônio Jorge de Lima Gomes Jorge Luiz dos Santos Gomes Copyright (c) 2025 International Journal of Geoscience, Engineering and Technology https://creativecommons.org/licenses/by-nc-sa/4.0 2025-04-30 2025-04-30 11 1 31 37 Study of Electricity Generation in Basic Sanitation Systems in Teófilo Otoni/MG http://geovales.com/index.php/Journal/article/view/195 <p>The aim of this study was to evaluate the implementation of different sources of energy generation in the facilities of the basic sanitation service companies that serve the municipality of Teófilo Otoni, Minas Gerais. It is, therefore, the water supply collection system and the sanitary sewage treatment system. The systems are operated by Companhia de Saneamento de Minas Gerais (COPASA). The energy potential was calculated based on the power and energy equations and was taken into account the quantity of each resource. In the water collection system, the volume of water collected for supply was considered; in the sewage treatment plant, the volume of sewage treated was considered. For each energy potential, the total value was multiplied by the corresponding energy price in the last auctions in which each source participated. In view of the estimated revenue, a financial balance was made concerning energy costs in the water supply and sewage system. Finally, it was found that the financial savings would be positive in the short term if the generation projects were implemented, which could reduce the fees and tariffs applied to sanitation systems.</p> Larissa Gonzaga de Carvalho Silva Tuane de Oliveira Dutra Luan Brioschi Giovanelli Francisco César Dalmo Copyright (c) 2025 International Journal of Geoscience, Engineering and Technology https://creativecommons.org/licenses/by-nc-sa/4.0 2025-04-30 2025-04-30 11 1 38 49 Evaluation of Approximate Methodologies for Dimensioning Reinforced Concrete Columns According to NBR 6118 http://geovales.com/index.php/Journal/article/view/192 <p>A comparative analysis was carried out between two semi-empirical methods for calculating double-supported columns established by ABNT NBR 6118 de 2023, “Concrete Structures Design – Procedure”, with emphasis on columns classified as moderately slender, with a slenderness index between 35 and 90. A comparison was made of steel consumption and the moment requesting calculation for 18 different columns (geometry and loading), considering the calculation methods (I) of the standard column with approximate curvature and, (II) of the standard column with approximate “κ” stiffness. The main differences obtained refer to the methodology for calculating second-order geometric effects for evaluating the structural deformability of bars after being requested by design loads. The analyzes carried out considered the three classifications of pillars provided for in the Brazilian Regulations: corner, end and center. Finally, it was concluded that methodology (II) standard column method with approximate “κ” stiffness proved to be more economical, with an indication of a reduction in the reinforcement rate of reinforced concrete columns varying in the order of 50% (± 34%) depending on the conditioning variables of each element analyzed.</p> Rafael Pereira Malheiros Thiago Fonseca Diniz Antônio Ribeiro de Oliveira Neto Thiago Bomjardim Porto Copyright (c) 2025 International Journal of Geoscience, Engineering and Technology https://creativecommons.org/licenses/by-nc-sa/4.0 2025-04-30 2025-04-30 11 1 50 56 Assessing the Impact of Land Use, Land Cover, and Precipitation on Water Quality in the Funil Stream, Ouro Preto – MG, Brazil http://geovales.com/index.php/Journal/article/view/197 <p>With population growth, the demand for water resources increases, intensifying environmental pressures. Among these, inadequate land management practices can significantly affect the integrity of aquatic ecosystems. This study investigates the effects of precipitation patterns and anthropogenic changes in the landscape on water conditions in a watershed located in Ouro Preto, Minas Gerais, Brazil. Data on water parameters were collected from the Minas Gerais Water Management Institute (IGAM), precipitation records from the National Institute of Meteorology (INMET), and land cover data from the United States Geological Survey (USGS), analyzed using ArcGIS 10.5/ArcMap®. The results indicate variations in water characteristics associated with increased surface runoff and the mobilization of geological materials, including heavy metals. These changes appear to be linked to soil exposure over time, as observed in remote sensing analyses. Additionally, the presence of mining activities in the area may be a contributing factor to water quality degradation.</p> Tasmine Miranda Ramos Rodrigo Esteves Ribeiro Francisco César Dalmo Luan Brioschi Giovanelli Copyright (c) 2025 International Journal of Geoscience, Engineering and Technology https://creativecommons.org/licenses/by-nc-sa/4.0 2025-04-30 2025-04-30 11 1 57 66
